My Hoyt Rampage XT has duel cams & so did my last Hoyt the cams went out of time on me once I shoot every day all year long & it took 3 years for it to go out of time
most common causes of this is string stretch, unequal limb adjustment, or cam issue (dirt grime or nicks in the cam)
slowly pull the bow back and have someone watch to make sure both cams roll over at the same time. Often the lower cam is the first to cause problems
If you cams are out of tune you should bottom out both limbs and then turn out the limb bolt in equal amounts
it is worth the money to have your bow tuned every year I have mine done every July/Aug. so I have time to shoot & make sure the Bow is shooting properly before hunting season
