They only output 200V to 300V - not enough to penetrate a gi.

Have you noticed?, no one has asked what a 'gi' is yet?

I presumed it's the thin conductive overvest mentioned by ericgibbs.

No. it's a thick cotton garment that wraps around the body, like **broken link removed**.

I think 'gi' is japanese for pyjamas?

The one in the picture is more like a Judo gi, exceptionally thick and strong, Brazilian Ju Jitsu is more of a sport (like Judo) than a self defence system.

We wear light or medium weight karate gi's, as in normal Ju Jitsu you don't use the gi to throw, except for a 'lapel and shoulder throw'.

Dismantle It, and put it into the knife's handle....It uses only an "A" battery.
I use them for little electronic fences....
My dog learnt where NOT to pee, in almost 3 nasty shocks....
