It is a must-have for anyone interested in electrostimulation.

The MK-312BT / F-312BT started as a community project to redesign the ET-312B and was retired several years ago. Based on the PCB V1.4 and firmware f005-MK312-BT, the MK-312BT/F-312BT offers incredible performance and reliability.

Built-in rechargeable, high-capacity modern LIFEP04 battery with 2.6Ah and integrated BMS provides unprecedented endurance of 24 hours at full load, with a charging time of only 4-5 hours.

Larger output transformers for smoother stim at higher output levels. Instead of a 7805 voltage regulator, a switching power supply with 98% efficiency was installed, and two large transformers provide ample reserves for electrostimulation.

Desktop case with handle for convenient setup and easier operation, eliminated unsightly screws on the front panel.

High quality components offer longer service life. The MK-312BT/F-312BT is equipped with 3 high-quality ALPS potentiometers and also features unique switch caps with lettering and arrows.

18 built-in routines including waves, intense, random, and 3 audio modes.

Up to 6 user-selectable routines can be added using the original software. The device is designed to easily communicate with the original software using a USB FTDI link cable to load custom routines or remotely control the device.

Full Stereo Audio modes allow audio based stimulation from mono and stereo sources (including SmartStim and Phaser waveforms). Connects to the headphone output of your computer, smartphone or any other stereo playback device using a Stereo Audio Cable.

Microphone input allows ambient sounds, music, or your voice into stimulation by connecting any PC-compatible microphone.

Bright, Crisp, Easy-to-read Backlit LCD displays current mode and output settings for channels A and B in any lighting situation.

Multiple Power Settings: 3 power ranges allow a finer adjustment of output level.

The MK-312BT/F-312BT provides a wide range of sensations, many intensely pleasurable – all with hands-free stimulation.

Unique TriPhase output creates a third stimulus waveform between channels A and B for even more variety and creative electrode placements. See our TriPhase Adapter for more information.

Advanced Menus allow fine-tuning of parameters.
Fully-compatible and refined version of the legendary ET-312B.
