I'm going to gererate some contoversy here, but I believe that srtongly in this reply that this must be said....I have been bowhunting a long time, and I try to keep an open mind when it comes to the overwhelming choices of archery equipment available. I also hunt Africa exclusively with a bow, and I have been fortunate enough to take over 50 plainsgame animals with a bow and arrow. Also, I have seen the successes and failures of countless other bowhunters while in Africa.
My experiences have taught me this....Any heavy duty, fixed blade, NON-MECHANICAL, broadhead that flies well is a good choice. STAY AWAY FROM MECHANICALS LIKE THEY ARE THE PLAGUE! I don't care who makes them, or how many celebrities endorse them, mechanicals do not perform well on the majority of African game. The outfitter that I hunt with will not allow the use of mechanical broadheads, and I applaud them for it. I'm suprised that there are many outfitters out there that still do.
Most mechanicals have light, flimsy blades which can bend, break, delfect, and fail to deploy. Additionally, mechanicals expend an enormous amount of energy, if they open correctly, resulting in shallow penetrations. No one here will argue that the anatomy of African game is different. We are talking about heavily boned, thick hided, animals that in my opinion are inherintly tougher by nature than most North American game animals. Your shot has to be nearly perfect, and the arrow must go deep, or you will end up needing to leave your trackers a bigger tip.
Have there been hunters who have taken giant African animals with a Rage or similar style broadhead? I'm sure there have been many... But, unfortunately, there has certainly been at least as many wounded and lost due in part to a mechanical broadhead failure. If anyone reading is a mechanical broadhead fan, it is not my intention to offend you. I use mechanicals here at home for turkeys. For small game, they are usually dependable, and they serve their purpose. But, I would never use them again on a deer....I'm sincerely trying to save anyone bowhunting Africa the stress and worry during a hunt that should be the trip of your life...
Leave the mechanicals at home... If you must bring them, keep them for shooting guinea fowl and other varmints.
