The only tool-less hunting sight I have had was a Hoyt. After a long day of goat hunting I got back to the truck and noticed I had a sight mount on my bow with no sight. (I found it on a later day.) I like the convenience of being able to make sight adjustments without fumbling around with allen wrenches, but the compromise is that this particular one didn't lock down as tight. I'm thinking of trying out the Toxonics since I've never had any trouble at all with their target sights, even on an overstressed, high vibration 3-D rig.
