I have the Globus Speed Coach Plus and it works great. Although, at this point it’s mostly used for recovery and massage, it has probably the largest array of settings compared to Compex, and I believe it’s the only EMS device of this quality that is programable.
It also has up to 120 mA per channel, more available current output than any of the Compex devices I know of.
The custom “Speed Coach” model has Derek’s Sprint programing on it and the Speed Coach Plus has all the bells and whistles.
Derek has also put together a great training manual for it.

Also, for someone with the knowledge of proper use and a Doctors prescription, for an added $200.00 they will add the Globus Genesy 1100 programing to the Speed Coach Plus model, here is a link to the added programs:

Which, with even the added $200.00 for the extra Genesy 1100 programing, your still $50.00 less than the Compex, with much more capabilities.
Also, using the available “split cables”, allows you to effectively Double the number of electrodes on each of the 4 channels… up to 4 per channel, equaling up to 16 total electrodes used at once. This saves a huge amount of time, and for many, makes EMS possible.
With the 120mA of current available, this unit has lots of current reserves.
