I learned this lesson in 2006. My 10 point I made a double lung hit (comfirmed in field dressing) he run about 300 yards. We found him about an hr. after I shot him and he was still alive. It took him about 1:15 to die.

Tell him to sharpen his broadheads and he won't have that problem. Dull BH's will cause those kind of things.
If you send a razor sharp BH thru both lungs, no deer is going to live 4 hours. Or travel a mile.
