Should I align my broadheads up with my vanes?
A lot of people still do this, but it is an unnecessary step with today’s modern equipment. A Thunderhead will fly just as well by just screwing them onto the insert tightly, no matter where the blades wind up compared to the vanes.
Do the Microgrooves really work?
Yes! NAP’s patented microgroove ferrules channel the air over the ferrule for better flight. More importantly, they slide thru and penetrate bone much better that standard ferrules. This really does help get better penetration.
Thunderheads and spin testing
It’s important to get any broadhead you have to spin true. The easiest way to do this with the Thunderhead is to screw the fully assembled head onto the arrow shaft, and tighten using the supplied wrench. Now untighten the head just a little and wait a few seconds. This will let the o-ring on the back of the ferrule regain its shape and help the head spin true. Now slowly retighten the head and you should be good to go!
Do I need to use the U.B.A.R. ring?
The UBAR ring is only needed when using the Thunderhead with small diameter carbon arrow shafts. The o-ring on the Thunderhead nests inside the UBAR providing support and helps the broadhead spin true. If you are using large carbons or any aluminum shafts, the UBAR ring is not needed.
Resharpened blades VS new ones.
It’s always best to use new blades when possible. No resharpen techniques will get Thunderhead blades as sharp as new ones. The Thunderhead blade is ground, honed, stropped and polished with three different grind angles which produce the sharpest blades in the industry.

"I have used your Thunderheads for years and feel they are the best head on the market. I got caught up in some of the new fangled ideas and had some poor results with other heads. I went back to my Thunderheads and harvested two bucks with them. I only shoot 60 lbs. and I feel the blade angle, tip design, and sharpness are just perfect for my set-up. I have harvested several deer and three bears also with your head. I just don't understand why other companies don't make their heads nearly as sharp as yours. I just wanted to take the time to say Thanks for caring about the sharpness and quality of your heads."

"Comments I would like to congratulate you on a great product. The 170gr Magnum Thunderhead. I am an African bow hunter for the past 24 years and have harvested over 1200 African animals to date. 90% of them were shot using a Thunderhead. The new Magnum is awesome!!! I need a heavy head for all my hunting and you just produced it. Thank you."
