I guess the question I have is, even with all the gadgets imagineable, how likely are you to take a wall hanger? I believe the percentages to be extremely low. With these low percentages, I believe we are far from becoming overly "odds-in-our-favor" hunters. The hardest thing is to get that bigboy in front of you, and then make the shot. They may make gadgets to help with the second, but the first will almost always come from hard work and knowledge.
