Burris Oracle 2

[Mas86]

Does anyone with one of these bow sights mind giving me some insight? I am having issues with the range finding portion of this sight. I am usually 2-5 yards off and always shooting low, for example the sight will say I'm at 32 yards then when I check with a separate range finder, I'll be at 35 yards. Is there something I did wrong during the set up? When I originally set it all up, I followed the instructions of sighting in with the laser, sighting in at 20 yards, stepping back to 35 + yards for SR1, then finally stepping back to 46 + yards for SR2. If there's any chance someone knows of a store that deals with these sights I'd be glad to take it to them to see what they can do, I just haven't been able to find one yet.
