Something to check on is if it is legal to hunt with enhanced hearing devices. I like the idea but last time I checked it wasn't legal in GA. I use electronic headphones at the range and double up when shooting the 50bmg
Not saying you're wrong, but I can't find anything in the regulations prohibiting them. No electronic communication devices are allowed. Meaning radios or cell phone communication. If you can find anything to document this let me know.
I'd like to find something. Just over 10 years ago I lost the hearing in my right ear (not shooting or noise related). I CAN hear well enough for most situations, but anything from the right side has to be close. And figuring out which direction is near impossible with one ear. It wouldn't be any worse with muff's. At least hearing something before it gets right in my lap would help. I've blown shots at deer 3 times already this year. Turkey hunting is near impossible for me now.
I have some of the Walker Razor's that I use at the range and I like them. I usually keep the volume turned off at the range, but it is nice to be able to communicate while others are still shooting. I haven't tried them hunting but need to.
