The Tiny Trainer for Finger-Kick – TT4FK
The TT4FK is essentially a Tiny Trainer 400 with a few important modifications. The new TT4FK is a transmitter that can be used with a Finger-Kick—so now we have an affordable little transmitter that is HANDS FREE. The charging of the unit has been changed to rechargeable battery. Additional, the levels have been changed so that of the nine levels, the first 8 go up smoothly and are identical to the levels 1 through 8 on the PT3000. Level 9 is identical to Level 11 on the PT3000. Also, the display now has a battery indication so the user can see when the TT4FK needs to be charged.
