Ended up going with the Motorola 750 series. Tied true easy too find (ebay) easy too use, and pretty hard too beat up. I had too separate the 2 uses I wanted for the radios, but I think it will work.
I will know by the end of next weekend, we have a shoot at Fort Gordon. We plan too use the two rigs and see how they work. It is more open and not as concentrated fire as say Knob Creek, but it should give us a good idea if this will be a viable option.
My guess from 24 hours of testing is yes, these will work just fine.......assuming you are wearing the opposite pair or have your own. If you don't we will be back too the old hand signal game.
I am curious how cumbersome these will become after a half a day of loading belts and moving around being we don't "wear" these for a living.
I'll keep you posted.
I have decided this much, and don't take this in a derogatory manner, but I don't think these are for the average hog hunter. After putting everything together I called the original idea holder back and gave him the final tally for 1 set and I pretty sure he hung the phone up on me......lol
None the less I'm pretty sure they will work for my purpose!
