But they do rob you arrow of some velocity and really worthless.
Really? I don't currently own a bow that has one(string suppressor) on it, but am thinking of adding one. Doesn't the twin suppressors near the cam/wheel on Mathews bows do the exact same thing, stop or slow the string down? They have had them now for a few years and I have never heard anyone say anything negative. Never owned a Mathews bow so I don't have any experience with any type of suppressor.
It depends where you place them. More towards the middle, I find it can slow an arrow down up to 10fps. More towards the cam, and little to no difference. I have had 2 people argue me and I break out the chrony and now all the sudden their suppressors are not as attractive anymore. I am sure I will get rotten tomatos thrown at me on this one. But I enjoy them.
I know Dave on here did some tests too and found something simular. Placement was key. He used an adjustable STS. The STS works a tad better as its tunable.
But it makes sense why it slows it down. You have a string coming to an abrupt stop. Where is that energy going? Its being wasted. A string will travel 3" or more past where it is at rest if you look at any high speed video. That extra 3" is exerting force on that arrow. Maybe not the whole 3", but the string keeps exerting force on the arrow until it leaves the string. A suppressor can short stop that. I also believe thats why the heavier arrow wastes less energy from a bow.
I think that is why the bowtech suppessors don't have as much an effect. They let string go little past. But stops the high frequency buzz.
This is just my tests. Since the two suppessors are near the cams on teh mathews, I can't see them causing issues.
