I second the motion of the BIRDHUNTDOG......practice with the same broadheads the you use in the field..That is truly the only way that you can be on and worry free. None of this resetting and oops ..forgetting the resetting. Just hunt!!!!!
NOTE WELL....mechanicals are recommended for use only with bows rated at 50lbs or more due to the heads requiring additional energy to open upon penetration. Can you hold that 50lbs for a few minutes to get that broadside or quartering away shot????? Sounds like youre new to this!!!
