The Official Tennant BioModulator®
Microcurrent that reads you,
then answers.
A handheld, FDA-accepted Class II transcutaneous electrostimulator. It touches your skin, reads the tissue underneath it, and changes what it delivers while the session runs. Dr. Jerry Tennant specified its programs and wrote the protocols it carries.

What it does
Your cells
run on voltage.
Dr. Tennant teaches that every cell works like a small rechargeable battery, and that a cell cannot do anything it does not have the charge to do. Move, signal, hold its shape, or build a replacement for itself.
That last one is the expensive one. Maintenance is cheap. Making a new cell is not. It is the difference between keeping the lights on and building the next room, and it is why voltage is the thing Dr. Tennant asks you to pay attention to first.

How much charge does repair actually take?
Dr. Tennant works in millivolts, because the difference between a cell that is coping and a cell that can rebuild is a number, not a feeling.
Tissue that has lost voltage keeps going, but it stops rebuilding. There is enough charge to hold the line and not enough to do the expensive work. Dr. Tennant teaches that this is the state a long-standing problem sits in, and that it is why the problem stays put rather than resolving on its own.
Healthy cells sit at roughly minus twenty to minus twenty-five millivolts. That is the working range. Enough to run, enough to signal, enough to maintain what is already there. It is a normal reading, and on its own it is not a rebuilding reading.
Making new cells takes closer to minus fifty millivolts. Roughly double what maintenance costs. That gap is the whole argument. A body can feel like it is holding steady and still be nowhere near the charge it needs to build something new, which is why Dr. Tennant starts with voltage rather than with symptoms.
The BioModulator® is not adding heat, vibration or pressure. It delivers microcurrent, meaning current at the very low levels the body already runs on, into the tissue it is touching.
And it runs this loop the whole time it is on the skin
- Reads From the moment you place it, the device monitors the electrical interaction at the point of contact.
- Responds Output changes according to what it is reading, rather than running one fixed signal start to finish.
- Adapts Two areas on the same person are not electrically identical, and neither is the same area an hour later.
Plenty of devices deliver current. This one was specified by Dr. Jerry Tennant for a defined method, and it arrives with the protocols and the education that method depends on. The instrument and the method are not sold separately here, because they do not work separately.
Low voltage is not
a local problem.
Which is why this is not a local device. Owners work a specific area when something needs attention, and run whole-body sessions to keep the whole system charged. Where to place it, for how long and in what order are all taught in owner education rather than guessed at.
A specific area
Placed on the area or the pathway the protocol calls for, in direct contact with the skin.
The whole body
Full body recharge is built into how Dr. Tennant now teaches the device to be used, not an add-on.
With the BioTransducer®
Dr. Tennant teaches polarity before voltage, because charge added to a circuit pointed the wrong way does not hold. That is the recommended starting order rather than a restriction, and the two can also be run concurrently.
Where owners apply it
- Chronic pain support
- Inflammation support
- Nervous system support
- Energy and fatigue support
- Recovery support
- Stress and sleep support
- Scar support

The Tennant BioModulator® is not intended to diagnose, treat, cure or prevent any disease. Individual experiences vary. Millivolt figures describe what Dr. Tennant teaches about cellular voltage and are not a measurement of any individual result.
How you use it
Place it on the skin.
Turn it on.
There is nothing to assemble, nothing to pair and nothing to charge. The Tennant BioModulator® is handheld, it runs on four AAA batteries, and a session lasts as long as your protocol says it lasts.
No mat to lie on. No cabinet to sit beside. No phone app between you and the device.
-
Choose the area
Work on bare skin, not over clothing. Pick the area or the pathway your protocol calls for. Skin contact is not a fussy requirement, it is the whole mechanism: contact is how the device reads the tissue underneath it.
-
Apply the device
Hold it against the area, or run it to a pad. The connection wire and electrode pads are in the case, so you can set a longer session and put your hands down. Select the program you were taught to use, and start at the lowest energy setting.
-
Let it respond
You do not steer it. It adjusts while it runs. The device reads the tissue, changes what it delivers, then reads what came back and changes again. When you are done, switch it off. Nothing to plug in, nothing to recharge, nothing to sync.
This is the one that touches you
The BioModulator® is a contact device. The BioTransducer® is not, it works near the body and through clothing. That is the cleanest way to tell them apart. Dr. Tennant teaches polarity before voltage, which makes the BioTransducer® the recommended starting point, though the two can also be run concurrently.
Start low. Every time.
Turning it up is not the same as getting more out of it. Dr. Tennant teaches starting at the lowest energy setting and letting consistency carry the result. An output the nervous system reads as normal traffic gets through. One it reads as an assault gets guarded against.
- Direct skin contact
- Four AAA batteries, included
- No mat, cabinet or handgrips
- At home, in a clinic, traveling
What comes with it
Open the case.
It is all in there.
The electrode, both connection wires, the pads, the batteries and the case itself. Nothing to order before your first session, and nothing you have to buy to make the device work properly.
- Y-Point Probe The snail electrode, for controlled placement on a targeted area
- 2-pin wire Runs two self-adhesive electrodes, hands-free
- 4-pin wire Runs four at once, for a broader area
- Electrode pads Reusable self-adhesive squares, for either wire
- Batteries Four AAA, included. Nothing to plug in or recharge
- Carry case Holds all of it, at home or traveling
Complete as it ships.
Fitted for particular work.
Your case covers the great majority of what owners do. A handful of areas have a shape the standard electrode was never meant for, and for those there is a contact made to match. Prices are shown online, and no device discussion is required to buy one.
What are you working on?
Use what is already in your case
The Y-Point Probe handles targeted placement and the pads handle broader coverage on either wire. For joints, muscle groups, pathways and whole-body sessions, that is the full toolkit and nothing else is needed.
Comb Electrode
Hair gets between a flat electrode and the skin. The comb's teeth reach through it, so contact stays even across the scalp instead of breaking every time you move.
Cosmetic Electrode
The face is small, curved and sensitive, and it is worked in short precise passes rather than parked on. The smooth handheld shape is built for exactly that.
Paravertebral, Double Bell
Either side of the spine, both at once, without holding two things steady. This is the one practitioners reach for most, because it makes a long session along the back comfortable for the person on the table and manageable for the person running it.
BioModulator Pet Brush
Fur is the same problem as hair, and an animal will not hold still for a probe. The brush reaches the skin and feels like being brushed, which is the difference between a session that happens and one that does not.
All optional contacts
- Comb Electrode Comb-style contact for scalp use and broader surface areas $250.00
- Cosmetic Electrode Smooth handheld electrode for gentle, precise facial application $160.00
- Paravertebral, Double Bell Dual contact for comfortable placement across broader areas $180.00
- BioModulator Pet Brush Brush-style contact for guided external application with animals $200.00
- Replacements and spares Extra pads and wires, whenever the ones in your case wear out Shop
The contact follows the area, not the intensity. A small joint, a broad muscle group and a scar are different shapes at different depths, which is the reason the range exists at all. Placement, timing and technique are taught in owner education, and none of them are improved by buying a bigger accessory.
The current generation
One device.
Fourteen programs.
There is one current Tennant BioModulator®, the Pro Elite. It reads the tissue it is touching and changes its output while you work, and it carries the full set of programs Dr. Tennant teaches. No tiers to compare and no quiz to take.
Fourteen programs.
One of them does most of the work.
These are targeted applications, not a sequence to work through and not a menu to browse. Your protocol names the program it wants, you select it, and the device loads it. Most of the time your protocol names the same one.
New to this generation
Tennant
A universal mode that did not exist on any earlier device. It is where the menu opens, and it is what most of Dr. Tennant’s protocols call for. If you owned an earlier BioModulator®, this is the one name on the list you will not recognise, and it is the one you will use most.
The other thirteen
Targeted applications, called on when a protocol asks for one.
- TEN-8 Familiar name Muscles, tissue and bone
- Infinity Familiar name Organ support
- V-NER Familiar name Re-engages the parasympathetic nervous system
- BBR Familiar name Bowling Ball Reset, for head and neck structural alignment
- Charge Energises the body’s circuits
- DOSE 3 Smart mode. Measures first, then runs
- Symmetry Pinpoints and balances where support is needed
- Acute Trauma Sudden, localised discomfort
- Chronic Pain Ongoing discomfort
- Joint Pain Long-standing joint discomfort
- Trigger Points Focused points in the head, neck and face
- Massage Circulation and relaxation
- Relaxation Winding down, stress and sleep support
TEN-8, Infinity, V-NER and BBR kept their names because the protocols that call for them kept theirs. What sits underneath was rebuilt for the current scanning technology, so where an earlier version ran inside fixed limits, the current one adjusts continuously while it works. Same name on the screen, a considerably more capable program behind it.

What actually changed.
Written for owners of an earlier Tennant device who want to know whether the current generation is different enough to matter.
- Earlier generations
- Ran a set output for the length of the session.
- Current generation
- Reads the tissue at the point of contact and changes its output while the session runs.
- Earlier generations
- You chose a program and guessed the level.
- Current generation
- DOSE 3 measures first and then runs, so the device sets the dose rather than you.
- Earlier generations
- A named program ran inside fixed limits, with little the device could vary once it started.
- Current generation
- The same named program was rebuilt for the scanning engine, so it adjusts continuously instead of running to a preset.
- Earlier generations
- A shorter program list, and no universal mode.
- Current generation
- Fourteen programs, led by Tennant, a universal mode that did not exist before and that most current protocols call for.
- Earlier generations
- The polarity step depended on separate equipment and setup.
- Current generation
- The current BioTransducer® carries its own rechargeable power, so the prepare step is a handheld pass over the body with nothing to plug in.
- Earlier generations
- Protocols were written for the hardware of the day.
- Current generation
- Dr. Tennant has updated the protocols since, and current owner education was developed against current-generation behaviour.
Trade-in allowances exist. Bring the device you own and the team will tell you where you stand before you spend anything.
Check my upgradeHow it is delivered
Louder is not stronger.
Earlier generations, and a good deal of what is sold today, run at a higher output. Dr. Tennant teaches that a higher output masks performance rather than adding to it. Push hard enough and you are beating on the cell, the way a heavy massage works the surface instead of reaching what sits underneath.
The current generation goes the other way. It is built to mimic the body’s own electrical signalling closely enough that the nervous system reads it as ordinary communication rather than as something to guard against. In Dr. Tennant’s framework that is the whole point, because a signal the body flags as noise is a signal the body defends against.
Which is why the capability that matters is not how much the instrument can send. It is how precisely it can listen before it decides what to send at all, and that is the part the current generation moved furthest.
The Tennant BioModulator® is not intended to diagnose, treat, cure or prevent any disease. Program names and descriptions are Tennant Health program designations.
The best device
is the one you
actually use.
No clinic visit, no appointment, no room to set aside for it. What Dr. Tennant teaches was built for the chair you already own and the quiet minutes you can actually find in a day.
That matters more than it sounds. The charge you are rebuilding responds to consistency, and consistency depends on how easily a thing fits into an ordinary day.

Prepare,
then charge.
Dr. Tennant teaches polarity before voltage, because charge added to a circuit pointed the wrong way does not hold. That is the reasoning behind the recommended order.
The BioTransducer® prepares. The BioModulator® charges. Usually in that order and in the same sitting, though the two can also be run concurrently.
Scalar field technology
Tennant BioTransducer®
Corrects polarity
- Held a few inches from the body, through clothing, nothing attached
- Placed where the protocol directs, rather than over the area you are about to charge
- Also used for inflammation, and for the emotional balance protocols on target meridians
- Rechargeable over USB-C, completely independent, and a general wellness device that needs no provider authorization
Adaptive microcurrent you are here
Tennant BioModulator®
Restores voltage
- Direct skin contact, reading the area and adjusting as it works
- Handheld and battery powered, electrodes and pads in the box
- A Class II device, and Tennant Health handles the authorization
- Do they have to be used in that order?
- It is the order Dr. Tennant recommends, and the reasoning is straightforward: correcting the direction of a circuit before adding charge to it is what makes the charge hold. That is a recommendation rather than a restriction. The two can also be run concurrently.
- Did the old BioTransducer® run off the BioModulator®?
- Yes, but only for power. Earlier models had no battery of their own, so they drew current from the BioModulator® and nothing more. It is worth saying plainly, because a lot of owners assumed the microcurrent was travelling through the scalar device and combining into some third kind of session. It was not. The BioModulator® was acting as the battery. The current BioTransducer® carries its own, so the question no longer comes up.
- Do I have to own both?
- No. Each one does something the other cannot, and plenty of people start with a single device. A discussion is the place to work out which one fits what you are actually trying to do.
- What does owning both actually change?
- The charge holds. Polarity is direction, and a circuit pointed the wrong way does not keep what you put into it. Adding voltage to it is filling a bucket with a hole in the bottom: the BioModulator® can put charge in and the body will not hold on to it. The BioTransducer® corrects the direction, so what goes in stays in. That is the difference between owning both and asking one device to do a job it was never meant to do on its own.
Correct polarity. Restore voltage.
Let the body do the rest.
Ownership
Taught by
Dr. Jerry Tennant.
The device is the smaller half. Dr. Jerry Tennant designed the modes and wrote the protocols that make it useful, and he still teaches them himself. Everything below comes with ownership, and it keeps arriving long after the box does.
- Getting started guides A Getting Started guide, a Quick Start guide and device orientation, so the first session is not guesswork.
- Protocol guides The named applications Dr. Tennant teaches, with the context that belongs beside them.
- Manuals and reference charts Full instruction manuals, and quick-reference charts for when you want an answer in ten seconds rather than ten minutes.
- Modes, troubleshooting, accessories What each program is for, what to do when something is not behaving, and guides for the accessories and for traveling.
- Monthly Power Hour A recurring live session for owners. Bring a question, hear what other owners are working through.
- Events, talks, conferences Continuing education through public talks, training events and the Healing Is Voltage® conferences.
Plus a warranty, repair and service, and a team that answers the phone.
What has changed
We are not running
current blindly anymore.
Earlier generation devices sent microcurrent into the body and left the rest to chance. This one scans the tissue, reads what comes back and adjusts while it works, and Dr. Jerry Tennant rebuilt his modes around what that scanning makes possible.
- Protocols, updated The named applications were rewritten for this generation rather than carried forward from the last one, with the modes and programs upgraded to match the technology underneath them.
- Treatment times, reduced Sharper targeting means a session asks less of your day than it used to. Streamlined, not shortened at the expense of the work being done.
- Guesswork, removed The device reads the area continuously instead of pushing a fixed current at it and hoping. Far more capability, applied far more precisely.
The last one is what matters most. When the current is guided by what the tissue is actually reporting back, the impact it makes on the body is significantly greater than anything a previous generation device could produce.

Questions
Everything people ask
before they buy one.
Grouped, so you can go straight to the part you are actually weighing. If your question is not here, the device team will answer it directly.
The device itself
What it is, how it behaves, and what using it is actually like.
What is the Tennant BioModulator®?
The Tennant BioModulator® is a handheld, FDA-accepted Class II microcurrent device that reads the tissue it is touching and adjusts its output while it runs. It makes direct contact with the skin, monitors the electrical interaction at the point of contact, and changes what it delivers in response. Dr. Jerry Tennant specified the program set and wrote the protocols that run on it, and it is used within the Tennant System alongside the Tennant BioTransducer®.
How does adaptive biofeedback work?
Rather than delivering one fixed signal from start to finish, the device reads the area it is on and changes its output in response. Two areas on the same person are not electrically identical, and neither is the same area an hour later, so the delivery is not identical either. That reading and responding is continuous for as long as the device is in contact with the skin.
How is it different from a TENS unit?
A TENS unit pushes one preset signal at an area and works by masking what the nerves are reporting. The BioModulator® reads what the tissue reports and changes what it delivers in response. That is the difference between overriding a signal and answering one. It is also why Dr. Tennant built his protocols on adaptive microcurrent rather than on fixed stimulation: a fixed output cannot follow an area that is changing underneath it.
Does the BioModulator® touch the body?
Yes. It is a contact device, applied directly to the skin rather than over clothing. Skin contact is what allows it to read the area while it works. That is the main practical difference between it and the BioTransducer®, which is held a few inches away and works through clothing.
What does it feel like to use?
Most people feel a mild tingling or warmth, and some feel nothing at all. An absence of sensation does not mean the device is inactive. Dr. Tennant teaches that a higher output is not a better one, and the current generation is deliberately built to work at levels the nervous system reads as ordinary signalling rather than as something to guard against.
Does it need batteries or charging?
It runs on four AAA batteries, included, so there is nothing to plug in and nothing to recharge. The BioTransducer® is the rechargeable one, over USB-C.
Dr. Jerry Tennant
Who is behind the device, and where the method actually comes from.
Is Dr. Jerry Tennant involved in the device sold here?
Yes. Directly, and currently. Dr. Jerry Tennant specified the program set on the current device, wrote the protocols that run on it, and teaches those protocols himself. When a protocol changes, it changes because he changed it. The guides, the training, the monthly Power Hour and the conference sessions come from him and from the people he trained, rather than from a third party working out what he meant from his published books. Tennant Health is the only company he supports.
Who makes the Tennant BioModulator®?
It is built for Tennant Health on a manufacturing platform Dr. Tennant selected specifically for what the hardware could do. He evaluated the adaptive microcurrent technology that already existed, chose the platform capable of carrying his method, and then designed the modes and wrote the protocols that run on it. Tennant Health is the only company Dr. Tennant supports, and the only source for the current-generation device.
Are the Tennant BioModulators sold on other websites the same device?
Tennant Health is the only source for the current-generation device, and the only company Dr. Tennant supports. Devices carrying the BioModulator name do appear elsewhere. Before buying anywhere, including here, ask three questions: which generation is this device, who specified the programs on it, and does Dr. Tennant support this seller. Those three answers are what separate one listing from another.
Using it with the BioTransducer®
Two devices, two jobs, and how they are meant to run together.
How is it different from the Tennant BioTransducer®?
They do different jobs. The BioTransducer® corrects polarity, the BioModulator® restores voltage, and Dr. Tennant recommends that order. The BioTransducer® uses scalar field technology, contact-free and through clothing. The BioModulator® applies adaptive microcurrent through direct skin contact. Polarity before voltage is a recommendation rather than a restriction, because charge added to a circuit pointed the wrong way does not hold. The two can also be run concurrently.
Do I need both devices?
You do not need both, but they are designed as a pair and the method is fully expressed when you have both. Plenty of owners start with one. The BioTransducer® is what people reach for to support relaxation, emotional balance, mental clarity and overall energetic balance, and it is the step that corrects polarity. The BioModulator® is the one that recharges, and that recharge holds best once polarity has been corrected. Either device is useful on its own.
What does owning both actually change?
The charge holds. Polarity is direction, and a circuit pointed the wrong way does not keep what you put into it. Adding voltage to it is filling a bucket with a hole in the bottom: the BioModulator® can put charge in and the body will not hold on to it. The BioTransducer® corrects the direction, so what goes in stays in.
Upgrading from an earlier device
For owners deciding whether the current generation is worth the move.
I already own an earlier BioModulator®. Is it worth upgrading?
Yes. The current device runs an updated method on a considerably more capable instrument. Dr. Tennant has updated the protocols since the earlier generations, treatment times have come down, and the full body recharge is now built into the way the device is used. The programs were rebuilt around the current scanning technology, so a familiar name like Tennant, TEN-8 or BBR now adjusts continuously instead of running inside fixed limits. Earlier generations delivered current and left the rest to chance. This one is guided by what the tissue reports back, and the impact it makes on the body is significantly greater as a result.
Will I recognize the programs?
Mostly, and one of them will be new to you. Several names carry over, but the programs behind them were rebuilt for the current scanning technology rather than carried forward untouched. The Tennant mode is a new universal mode that earlier owners have not used before, and most of the current protocols call for it. The program list is also not arranged in protocol order. It is a set of targeted applications that the protocols draw on.
Can I trade in my earlier device?
Yes. Trade-in allowances exist and the Tennant Health device team confirms eligibility before any purchase. Bring the details of the device you own to a complimentary device discussion and they will tell you where you stand before you spend anything.
Buying one, and owning one
Authorization, what arrives, and everything that keeps arriving afterwards.
Do I need a prescription or provider authorization?
Yes for the BioModulator®, no for the BioTransducer®. The BioModulator® is a Class II transcutaneous electrostimulator, so ownership requires authorization from a licensed healthcare provider. Tennant Health coordinates that review with you as part of the purchase, so it is not something you arrange alone. The BioTransducer® is a general wellness device and does not require it.
Is there anyone who should not use it?
Yes, and that is part of what the provider review is for. Suitability is worked through with a licensed healthcare provider before a device is authorized, and the official instructions supplied with the device govern its use. If you have a medical condition or an implanted device of any kind, raise it in your device discussion and with your own provider.
What comes in the box?
The device, the Y-Point Probe, the 2-pin and 4-pin connection wires, self-adhesive electrode pads, four AAA batteries and a carrying case. Nothing else needs to be bought before your first session, and nothing optional is required to make the device work properly.
Do I have to buy accessories?
No. Everything the device needs is already in the box. The comb, cosmetic and paravertebral electrodes and the pet brush are optional, and each one exists for a particular shape or setting rather than to improve results.
What does ownership include?
Every guide, protocol and training resource Dr. Tennant teaches, plus warranty, service, repair and direct support. Getting Started and Quick Start guides, protocol guides, instruction manuals, reference charts, guidance on modes, troubleshooting, accessories and travel, the monthly Power Hour, and events and conferences. All of it comes from Dr. Jerry Tennant and the people he trained, rather than from a third party interpreting his work.
How do I buy one, and what does it cost?
Devices are purchased through Tennant Health rather than checked out online, because the provider authorization review is part of the process. Pricing, package options and financing are reviewed privately in a complimentary device discussion. Accessories are separate and can be bought directly from the shop with prices shown online.
