I don't think they are hard to tune, or do you mean keep in tune? I have a 05 cam & 1/2 bow and it is no more of a problem than the singles, but you really can't compare it to my old singles, or the twin I have. The new ones are very user friendly except for the fact that all bow manufactures could easiler give a center shot measurment, but don't. I don't know why other than maybe their the ones selling the lasers.

ANY BOW MANUFACTURES HERE. DID YOU HERE ME. EASY WAY TO ONE UP THE COMPETETION I WOULD THINK.
