The Thunderhead is widely recognized as the finest fixed blade broadhead ever created. The sharpest blades. The best quality. More animals have been taken over the years with Thunderheads than any other broadhead.

  1. 5 out of 5

    Using for over 20 yearsI have been using NAP Thunderhead 100's for as long as I can remember. Being a tinkerer with all things archery I have tried many different broadheads, but always end up back at the Thunderheads. You will need an arrow spinner to ensure that they spin true due to the rubber gasket. It does take some time, but if they spin true I have tested out to 60 yards with same POI as my field points. When I was shooting older slower bows it was not as critical, but with the new speed style bows it is critical.

    On animals my experience is with numerous whitetails and one bear. The Thunderheads leave the best bloodtrail of any broadhead I have used.

    I would recommend these to anyone.

    Keep Coming Back to TheseI have tried all the fancy mechanical heads around, and several other fixed heads too. I honestly don't know why I do that. I have taken more deer with these than all the others put together. These are tough, fly true, and make massive wounds, they put game down quickly. I admit i have to make minor adjustments to my sights with these right before the season starts, but once that is done, every head hits where I aim!
