Just a quick note about Tri tronics warranty service .I sent my pro g2 exp transmitter back cause antenna would not come unscrewed.I called them on 5/17/10 told them about problem they gave me a repair # sent it to them that same day then on 5/27/10 i received my transmitter back from them so i open box up and to my surprise there is a brand new g3 transmitter with charging base included plus no charge. Just letting everyone know what a great company they are to deal with.:10sign:
