My 3300 works great, has good depth, light and easy to swing for several hours and I really like the layout of the control housing. My only problem is with the numerical target indication. It jumps all over the place even when I use it in my test garden and try to swing it at the same speed and distance above the ground. The numbers jump from 20 or so to 199 and everything in between-and this is over a penny at 2" deep. Is this what yours was doing? When BH fixed yours did it affect the depth? Thanks
