I've got a pair of Collet Communicators.. they're 2 channel, 1 private, and one universal, (universal channel is the freq. the snomobile grooming machines use as well, to warn you they're just around the bend.. not applicable here I dont think heh)
I used them mostly for the step kid, when teaching him to ride offroad on quads/dirtbikes.. havent really used them since the lil woman took off with him, so if you're interested, I just might be willing to part with them..
anyhow, they're voice activated.. I've had the best luck blowing into the mic a bit to get it activated, then talk... once they're set up right, they work GREAT.. the range seems to vary with battery strength.. usually up to no less then a mile when fully charged.. the battery packs connect directly to a 110VAC charger, that's supplied with the communictors..
I've either bought, or demo'ed every type of communicator out there, and the Collets seem to be the best all around
lemme know if I missed anything
