All good pieces of advice.
Will re-emphasize the importance of keeping fingers and thumbs below the string, under the guard. You'd think it would be obvious, like you said, with the way my crossbow's (wicked ridge warrior) grip is made, but I had an experience where my friend (non hunter, but still a sharp guy) was about to shoot it when someone noticed his thumb was above the guard. he was seconds away from severing part of his thumb. :shock:
Mine has an anti dry fire safety as well and it does work...but yeah, don't test it.
Also good tips on test cocking it. I've cocked mine in and out of the treestand. I carry it up with a rope just like my rifle, and usually prefer to chocolate chip cookie beforehand. You can search for threads on how to decock the thing. I've tried manually and find it very hard, but lots of folks do it that way. I shoot an old bolt as suggested with a stump shooter tip (small game, big blunt plastic/rubber tip) cause it shoots it so far into the ground I've lost arrows before.
Wear a safety harness. Not anything to do with a crossbow but I imagine a fall while using a crossbow hurts about as much as a fall while using a rifle. Do it for your daughter...that's why I started using one (last year...embarrassed face).
And have fun!
