When mechanical broadheads were first introduced to the bowhunting public, they quickly earned and deserved a reputation for being terrible. Blades falling off and heads refusing to open on impact were just two common complaints. They were also very expensive. However, technology has overcome the first two of these three complaints, and today the best mechanicals are just as reliable as the fixed blade heads. Plus mechanicals offer some important advantages to the bowhunter willing to pay the extra cost. They are easier to carry and keep sharp in a quiver and they cut a bigger hole than fixed blade heads of the same weight are just two.
If you are having trouble getting your fixed blade heads to strike the target in the same spot as your field tips, you may want to give mechanicals a try, and if you shoot a short arrow, as with an overdraw or a crossbow, there is a very good chance that mechanicals will give you noticeably better arrow flight. And as for the third complaint listed above? Well, mechanicals are still very expensive, even at NZAP prices, but hey, two out of three isn't bad.
The Tekan is a new type of mechanical broadhead from G5 Archery. The Tekan is constructed of one-piece stainless-steel, with no screws or other fasteners to come lose, and a tough .625-inch (16mm) cut-on-contact tip. The folding blades are .040" thick and simple to replace. The folding blades are held closed with a simple spring washer until contact with the target causes the blades to ratchet open. The spring washer also keeps the blades from closing while they are passing through flesh, insuring maximum wound channel and blood trail.
G5 Tekan replacement blades are .040 inches thick with a 1 1/2 inches (38mm) cutting diameter.
There are enough blades with O-rings and washers in each packet to do three broadheads.
The Spitfire mechanical broadheads by NAP are without doubt the finest on the market. Where lesser mechanical broadheads rely on "O" rings to hold the blades in the closed position, the Spitfire blades are held in place by a patented snap-lock system, which is made possible by the extreme precision used in making these fine broadheads.
Here is what the folks at NAP say about them:
Spitfire is undoubtedly the most trusted name in mechanical broadheads! Spitfires fly straight with pinpoint accuracy, perform better than any other mechanical thanks to the sharpest Diamize blades, and stand up under the toughest conditions. And the practice blades mean you can save your super-sharp hunting blades for the big day.
Spitfire broadheads are available in 80-grain, 100-grain, and 125-grain sizes. Blades are .030 inch thick stainless steel with a 1/14 inch cutting diameter for the 85-grain head, and a whopping 1 1/2 inch cutting diameter for the 100 and 125-grain heads.

If you want a really cheap (like free) broadhead target, get a cardboard carton about half a meter square and about 150 to 200mm deep and stuff it very tightly with crumpled-up newspaper. Now attach two strong cords to adjacent corners so the box can be suspended in front of your backstop. The idea is that the arrow with the broadhead will penetrate the box without a complete pass through leaving the broadhead sticking out of the back of the box. To remove the arrow, unscrew the broadhead and pull out the arrow. This only works if the box is suspended because the swinging box absorbs most of the energy from the arrow.
If the arrow passes through the box use more paper. If the broadhead doesn't protrude from the back of the box, use less paper. If you miss the target, get a bigger box or stand closer. If you still miss the box, you're on your own.
