FWIW - if you haven't already, give them a call (Norac) and ask for some guys that use them that way in your area. Ask them if they had any that returned them, they will tell you, and give'em a call. Norac has a pretty good product - pretty streight shooters also. Some guys want a plug and play and don't take the time to understand a unit and adjusting it - they won't be happy. Those that follow mfg directions will find it usefull and adds a return to the investment.
