looks like i got that wrong... in the vid mergryphon tests the ohm of the wire with the Vari, then puts the completed iatty on her GG...
So until i get ahold of a GG... looking forward to the VV version hopefully this year sometime... i'm off to see what folks say about using it on a Vari...
I use it the iAtty on the provari all the time. Works like a champ. Also works nicely on the BuzzPro. Should be one with a higher Ohm rating to do this. 2.2 or higher. When I make a LR coil, under 2.0 Ohm, I slap it on the GGTS or a Silver Bullet.
In short, it works on almost everything. VV just makes it easier since its not quite an exact science getting a specific Ohm rating on the coil.
