Welcome to our tech, tips, and tuning page. Here we're constantly adding to our library of information. Visit often and make use of these resources any time. We're glad to help.
Check out our video library. We have how-to videos on how to use our products, some of the testing of the new Adcock longbow, some great footage of archer's paradox.

You'll see we have all the Dr. Ed Ashby reports for you. He has done some phenomenal work testing arrows and broadheads. The interesting this is that he has always used both longbows and compound bows in his testing. Here at Alaska Bowhunting Supply our roots are in traditional archery, but our GrizzlyStik carbon arrows and our GrizzlyStik single bevel broadheads are being used by compound shooters all over the world.
Single bevel broadheads penetrate game animals, especially when encountering bone, better than any other design ever offered to the bowhutning community. We have single bevel broadheads from 100 grains to 300 grains to fit any bowhunting situation you'll ever face. Our GrizzlyStik broadheads are built to perform when everything goes wrong. When you're a serious bowhunter the last thing you want to worry about is if your broadhead has what it takes to get the job done when you're ready to release the shot. Our GrizzlyStik broadheads have been severely tested and they've passed with flying colors. If you don't settle for less than the best when hunting, why settle for less than the best in broadheads? Check out the broadhead data below and you'll understand why we're so confident in our GrizzlyStik single Bevel broadheads.
Our GrizzlyStik carbon arrows are the perfect driving force behind our broadheads. No matter what broadhead you use if your arrow doesn't retain energy and deliver it upon impact you're not getting the performance you deserve. Our continuous taper design is ballistically superior to any other design. Our GrizzlyStik arrows are fast! Fast from the bow, fast to recover from archer's paradox, fast to the target, and then BOOM! First they drive forward the mass of the arrow pushing, then at a point during the penetration the weight forward design pulls the arrow through as well. If it weren't for the unique design of the GrizzlyStik with its extreme forward of center (EFOC) we couldn't make such a claim. The penetration potential is amazing.
If you combine our arrows with our broadheads you have an unbeatable system. You'll never have to second guess your equipment. You just concentrate on making the shot!
FINDING THE FOC OF AN ARROW
The AMO-Standard F.O.C. balance formula is: %FOC = (100x(A-L/2))/L
A = Balance point as measured from the throat of the nock to the point of balance.
L = Total arrow length as measured from the throat of the nock to the back of the point.
(Do not include the length of the point in this measurement.)
1. Measure the arrow length from the throat of the nock to the end of the shaft. (Back of the point) e.g. 28.5"
2. Divide the total length number by two (2). (Or multiply it by 0.5.) e.g. 28.5/2 = 14.25 or 28.5 x 0.5 = 14.25
3. Find the arrow's balance point. Measured from the nock throat to the balance point. e.g. 19.0"
4. Subtract half the total length from the balance point number. e.g. 19.0" - 14.25" = 4.75"
5. Multiply that result by 100. e.g. 4.75 x 100 = 475
6. Now divide that number by the total arrow length. e.g. 475 / 28.5 = 16.6% FOC
Example:
A 28.50” (BOP) arrow has a balance point of 19.00”.
Half of the total arrow length is 14.25.
Subtract 14.25 from the 19" and you get 4.75".
Multiply that by 100 = 475.
Now divide 475 by the total length which is 28.5 = 16.6.
Your FOC measurement is 16.6%
