My wife is starting to get involved in my photography. She is learning and I have used her as an assistant and second photographer. I am considering of purchasing 2-way radios so if she has any problems or I need her somewhere, I can communicate with her without me trying to find her. The 2-way radio I was considering is the Trisquare TSX100 or TSX300. Does anybody have any experience with these radios? The radios will be used on weddings and outdoor events where there is lots of ground to cover.
