there is 3 manufacturers of injectors worth getting IMO, basstackle, fat guys fishing and N2 manufacturing. i own 3 basstackle (10oz single, 6oz dual and 3oz triple) and a 6oz dual fgf injector and they have all been great. i dont own an n2 injector but i hear great things, so i wouldnt hesitate to go that way either. there are a few others that make a good injector, like lurecraft (i dont like the screw on nozzle, i have one and its tedious after a bit, very secure though!) and bait junkies (very limited availability, if at all).
