Any bow can get out of tune. The new Darton has the only true two cam bow out there with there new Pro 3800. As for as any bow today it is a fairly easy fix to time the cams. Just buy from a pro shop that you know you can get service after the sale. If I may add to help, when and if you get one mark the cam where the string comes off and when you see that is different have it retimed-a tune up, and all will be ok. BTW that could be a couple of years, depending on how much you shoot.
