Hold your horses folks..
It might not be completely his fault.

Last year, when I was checking my equipment a couple weeks before opening day, I discovered that one of the two remaining mechanical broad-heads I had was bent and that it was time to go replace them.
Went to my local sporting goods store and they didn't carry my normal spitfire mechanical heads so I had to substitute another brand that looked similar.. There were differences.. My originals used a friction retainer to hold the blades closed. The new ones used what looked like a buna 0-ring like you'd find in any hydraulic system.
I was actually turned on by the idea of the o-ring since any hardware store would have replacements when I ran out.
Long story short.. I shot 3 deer, lost 3 deer.. all in a 2 week period. I was so pissed off at myself I almost wanted to quit hunting.. I knew my aim was true but couldn't figure out why I could never find my kills.
It turned out, the 0-ring was so strong that it was preventing the broad-head from opening and I was effectively just poking holes in them.. I found this out when I retrieved an arrow that passed right through (completely covered in blood) and stuck in the ground still standing and pointing directly at my firing position.. 0-ring still intact, broad-head still closed tight. Pissed off is an understatement.. but not at myself anymore.. Manufacturer ended up giving me a full refund and two extra packages of any heads I wanted.. shipped free..

Don't be so quick to blame the newbie.. it could be an equipment problem. Not saying it is, just that it could be.
