We have people come in the shop all the time and buy radios and want to save money but there right back in a few months buying the better stuff. I know I done it too lol.
the 3R Pro will let you change from 3 different speeds depending on your reciever. I currently have the 3 Pro and had to show others there is a difference between the 3R and 3R pro. My LHS didnt even know.
