I have the duel beam and it would read the bottom but not my jig. on the narrow setting it would work. I just sent it in, I’ve sent it in before and they replaced the head unit. Hopefully this will take care of it. If i were you i would send it in and for i believe under 90 bucks they will fix or replace anything that is wrong with it and give you an additional year warranty on your unit. Marcum is top notch in standing behind their product from my experience with them.
