Bought a thumb release the other day , today shot it for the first time ( haven't adjusted the tension and everything yet) my point of impact is about 8-10 inches lower than with a wrist strap. Is that normal or have I just not got accustomed to it yet?

I just bought one a few weeks ago. I've always just used a wrist strap with finger trigger. The thumb release required a new anchor. So that moved my peep and sight pins. But once I got that all dialed in I'm shooting better than ever before.

Good deal
Thanks for the input

I'm also trying to use back tension to fire the release instead of pushing the thumb barrel.

Tried a thumb release for a season. My anchor point changed significantly. Killed a couple with it that year, but never could get comfortable. For me, a wrist strap is a better hunting release.

I just recently swapped to a thumb release, while I'm not using it for the back release type of shooting, it has helped me to be more consistent.

I switched from wrist to thumb 2 years ago and it didn't effect anything, buddies have tried it and shot same as theirs also

It might have thrown all your anchor points off.

Thumb release made me a much better shooter. I'm on my second one now, one that locks on string, it's a game changer in the tree, you don't have to hold it or worry about where it is

I switched to a thumb release several years ago. it seems like it did change my POI a little but not much. I prefer it over a wrist release any day...

Thanks for everyone's input, it groups realy well maybe even better than thumb release but thought items odd shooting that much lower . I didn't want to swap the sight if it was something I was doing

I shot one briefly...didn't see a noticeable difference in POI.

on an unrelated note, if you've never hunted with one, I'd recommend wrapping it in tape or something before the weather gets cold. I can't shoot a bow with gloves on and I went to draw mine on a particularly cold day and that thing was like grabbing onto a block of ice with bare hands.
