I've read in places that these type devices "increase" arrow speed and "tighten" your groups. Is this true and how does it accomplish this if so?
They will not increase your speed unless you take your string silencers off, which you can do and that will result in an increase in speed. Tighten groups? I didn't notice a change in mine, but that may depend on form, etc. A string Suppressor also decreases hand shock
