I purchased one this year and put it in my new switchback.The pin doesnt adjust but of course u have the option of adjusting the whole site itself. Anywhere up to 30 yards i shoot the same place without adjusting anything. I mostly practice froma ladder stand i set up but had no touble shooting from the ground. I think the site works great. no complaints here. As long as ur shooting less than 30 yards you shouldnt have a problem whether ur shooting from the ground or out ofa tree. it might depend on how fast ur bow shoots though.
