Whether you've been into electrostim for awhile or are just getting started, there is something to be said about having the best and safest equipment. Until now, there was no single device that offered the power, safety, and ease-of use of the ET312B. American designed and crafted. Not a repackaged TENS unit or signal generator. This instrument is the result of over 3,000 hours of focused design effort, with one single end in mind…

E-Stim Excellence!

There are power units that sell for less, but none of them offer 18 pre-programmed modes -- each designed by an experienced e-stim master to provide a variety of sensations all under computer contol without continuous knob twiddling. Each routine can be quickly selected on the bright, backlit display using 2 pushbuttons. Once selected, the tempo and frequency are easily adjusted using a single "MultiAdjust" knob, not two or more on other power units. And the intensity level is easily adjusted using separate knobs for channels "A" and "B" with the current levels clearly displayed at all times.

Powerful yet Precise

The ET312B is powerful yet precise. Feature-rich and intuitively easy to use. There is no other power unit like the ET312 anywhere. Mention the ET312 to anyone into e-stim. They'll know what you're talking about.

I use both the ET312B and ET232 units a few times a week and have had some amazing sessions over the years. If the price or features seem too much, I suggest the ET232 which has many of the features found in the ET312B in a smaller and more affordable package.
