I have a "factory" built hip/chest mount MXT purchased last year in AZ. Bought it for the little woman...her neck/back is getting arthritic...Might have something to do with spending the last 50 years trying to keep me in line! It sure is lighter & when properly worn, stays pretty much out of the way.
There's a coupla major differences tho...1) The cable from the coil may need to be longer & 2) You'll need to either get the "factory" mounting pad from White's that secures the 'tector to your belt, or fabricate one. IMHO, one could be fabricated quite easily from saddle leather or heavy nylon seat-belt type material.
If you have interest in converting yours, I'll see about getting some pics/specs. If you want a new, factory one, (I think he still has 1 or 2) I can put you in touch...I think they were a few extra $$$, but maybe you can make a deal!?
Enjoy!
