Anyone use these before? I want to get them for Coyote hunting and maybe Whitetail too. The mechanical might help for shooting 20-50 yards.

I dont know about them but I know a guy that USE to shoot Montecs and has lost a couple of deer and he swears that he hit them good. But i dont know, they look like good broadheads to me. I think any BH will work if you hit them in the right spot.

Anything thing held in buy an O-Ring you have to make sure the blade is not popped out b/4 you shoot.

they have an o-ring on them

I shot a doe with one and got rid of the other ones!! I double lunged her saw her drop and I found 1 drop of blood. They leave a very small hole entrance and exit! Hit them correct they will die if its blood your looking for this is DEFINATLY not your head!!

They actually just redesigned the Tekan II. Made a larger standard cutting diameter (now 1.5"), and addressed a couple concerns they had about the origianl Tekan II. I can't wait to try the new ones! Check out these two links...
