good evening, I came across a post about an equinox 900 operating erratically. I just registered for the site but cannot find the post and was wondering if the person with the 900 ever got the problem fixed. I sold my 800 and upgraded to a 900 and it is constantly chattering picking up targets on every swing and the vdi numbers are all over the place. I tried everything but ended up sending it back less than a week after owning it. the repair shop now has it and i am waiting to see if they find anything wrong with it, i also sent both coils along with it. I never had any problems with my 800. I took the 900 to 5 sites (tot lots) I frequently went to with the 800 just to see what the 900 would do and it was going crazy at each site. frustrated as the ground is not completely frozen yet and wanted to get a couple more chances to use the 900 before it really snows hard. thanks for reading
