Dr Ed Ashby
Regarding our chosen hunting tools, the ultimate details involve the effect
of the arrow and broadhead as a unit upon the target animals. In this area
the most unquestioned and thorough studies have been examined by Dr Ed
Ashby. His works on the effects of broadheads on game animals are
comprehensive, and well documented. They are, while technical, easy reading
and we encourage you to take the time to go through them. They are the
reason that we embarked on the Tuffhead™ project.
Dr. Ed Ashby's Lethality Studies are listed here in pdf and chronological listing
As you come to understand the factors that Ashby considers, and begin to explore
your own equipment in light of the details he proposes, you will
these Archery Formulas as a basis for
comparisons of equipment. They each relate to every form of hunting with
a bow and as you come to understand each of them, you will realize, as we
did, that the Tuffhead™ will meet your every need.
In January 2012, Dr. Ed presented a discussion at the Traditional
Bowhunters Expo in Kalamazoo Michigan on the Ultimate Hunting Arrow,
What You Need to Achieve It, and the facts you need to know to back it
up. With Dr Ed's permission, the program was recorded and Dr Ed provided
his slides to accompany the audio. This series provides a
very interesting and easy to understand follow-up to his many studies on
arrow performance available elsewhere on this site. Set aside an hour or
two and listen to what Dr. Ashby has to say...

Troy Breeding and Tuning the EFOC Arrow
Troy Breeding participated with Dr Ashby at this seminar and discussed tuning your arrow shafts for efoc and uefoc arrows. His portion of the program can be found in clip 20 of the video series and in more detail in our reference room to the left under "Tuning the EFOC and UEFOC shaft".
Again in May of 2013, Dr Ashby gave this presentaion at the 2013 Pope & Young Convention in Dallas. At these sessions Dr Ed discussed both BUILDING AND TUNING THE EFOC ARROW and also THE MANY ATTRACTIVE FEATURES OF THE EFOC ARROW. We have assembled this presentation in a series of videos that you can WATCH FROM THIS LINK.

If you are beginning to work on tuning your arrow shafts or are embarking on heavier arrows, you probably have never heard of the Archer's Paradox, or possibly not gotten a clear understanding of this issue. This link to our single bevel broadhead website goes into some detail on the issue and also links out to other sources.
Basic Anatomy -
With a good knowledge of the equipment side of archery in place, the better you
better hunter you become. We do not claim to
be the end all source for the biology of game animals, but in this
anatomy images folder we endeavor to
provide some basic anatomy information on some aspects of popular archery game
We'll add to this area as we can.

Hunting big game with a stick and string has certainly evolved over the ages and our understanding of the factors affecting success as archery hunters demands we evolve as well. The article below was written by three noted authors and archers who take a scientific approach to educating us about the factors affecting the lethality of the arrow. This team has provided links throughout the article to research studies which help the reader understand the various factors involved in selecting the proper arrow and broadhead combination for elk hunting. Sit back, take a good read and delve into the “science” of archery hunting.
