Current set up: Carbon 12 on bow with HDI on trolling motor for 2D and AT connected with Ethernet to console with Gen3 SS3D. Planning on moving Carbon to console and buying a Live when they go on sale ( not in tournaments etc so don’t mind being 2 generations behind). I see that you can buy the head unit only and was wondering if the 3D would work with the Carbon or should I go with the AI 3 in 1? Could I also stack the Gen 3 on bow just for mapping?
