    Default Is STS can cause breakage of Limb??

    Hello Martin Pro's

    I have this question in my head after the break of lower limb to a bow friend's and mine, few weeks after we are mounted a STS (Fuse for him and Limbsaver for me) on our bows.

    Can you give me a light on this problem??

    My bow is a Pantera 2007 and my friend have a C4 2007 Nitrous X (second breack on his bow)

    Thanks

    I'd say YES... I guess that the sudden stop of the string movement can cause more stress to the limbs.I won't use my homemade STS unless i go hunting, which isn't likely to happen soon

    I am not a pro but a long time hacker. I can't see how an STS can harm a limb. But I'll tell you what I have noticed that can. I watched a friend shoot his bow to help him get setup. He drew back hit the draw stop and then twisted the heck out of the limb, because like my bow his shooting string is off center of the limb and pulling beyond the stop twists the limb. So after we set his draw length and draw stop to match it I felt better about how long his bow might last him. But unless someone who is an expert can explain how stopping the string could cause a problem I don't see it.

    there is no way an STS is going to cause limb breakage.

    And two different STS...one Limbsaver String deccelerator (me) and one STS Fuse Stealthshot (friend)...

    I think that is the setting of STS (to close of the string)...or a problem on 2007 limbs...

    If anything, I'd think the STS would cushion the overtravel of the string. If you look at a slowmotion of a bow withoun an STS, it is amazing how far the string traevls beyond brace position. It wrenches the cams in the opposite direction, and the limbs also flex again. The STS reduces that effect.

    I have 4 different bows, all with STSs on them, never had a problem. Like stated above there's is a good chance your friend is pulling beyond the wall and that could be tweaking the limbs.

    Would so many manufacturers be incorporating them into their bows right from the factory if there was a problem ? To put your mind at ease just check a new catalog for new bows and see how many come with an STS,check Martins lineup...

    you must have 1/16" gap between string and stopper, if it's resting on the string it does create extra force on the limbs and cams.
