Im looking for tips on purchasing a pair of two-way radios. There seem to be a ton of different models, and Im completely ignorant of the differences. Im not looking to become an expert, just looking for some tips on what to look for in a radio. I will be using them on river floats to keep in contact with the guys that I am fishing with, and to tell the little woman (back at camp) to hold breakfast because they are still biting. Thanks!
