Just five shots at 100 yds will reveal your effective range!



​Shooting within your effective range gives the hunter more accuracy, more success and better experiences. 
Determinator Targets allow you to easily determine your Effective Range. 

How Determinator Targets work:

  1. Set up to shoot at 100 yds
  2. Shoot 5 rounds aiming at the bullseye (additional bullseyes included for guns sighted in high)
  3. Score the ring that all 5 shots are within (this ring identifies your effective range)

Formula-based, progressively spaced “Staggered Ring” design

We’ve done the complicated differential mathematics required to determine the progressive spacing of the concentric, staggered rings on a Determinator Target. This patented system allows you to shoot at 100 yards and identify your effective range. And, shooting five shots minimizes any margin for error. Once you’ve shot the five rounds you simply identify the smallest ring that encompasses all five shots and then read the number on that ring which will be between 100 yards (largest ring), and 600 yards (smallest ring). That is your effective range! 

Available for eight popular big game animals, shown below, covering 25 North American Big Game species.
We also have three feature loaded Sight-In targets, Plinking Small Game Targets with distance staggered rings, our patented Plains Game African Safari Targets and our Effective Range determining Competition Targets.

Right Size Vitals

Choose the Determinator Target that’s right for the animal you are going to hunt.

Shoot from all shooting positions

It’s important to know your effective range for all conceivable shooting positions before you hunt.

Why five shots?

We did our homework in determining how many shots are required to determine your effective ring.

Proven effective at reducing wounded or missed animals

Multiple aim points for guns sighted high

You’ll notice a series of three additional bullseyes located directly below the bullseye at the center of a Determinator target. These “Stacked” aim points are for rifles that are sighted in at 2”, 3” or 4” high at 100 yards allowing you to use these targets no matter how your gun is sighted in. A residual benefit of the multiple aim points is that they help train you to focus on a specific spot as opposed to an area.

Provide “No Bull” evaluation, instill “No Doubt” confidence

Determinator Targets provide a fair and accurate “No Bull” assessment of your true effective range, something that previously has been relatively difficult to accurately determine and, therefore, subject to testosterone-based embellishment. Just because one is able to hit their target once at a long range doesn’t mean that they can consistently make a one-shot humane kill at that range, which is the definition of “effective range” and the goal of Determinator Targets. Half the battle in any skill based effort is confidence. Using Determinator Targets instills "No Doubt" confidence by providing any shooter with demonstrable knowledge as to what their effective range is so that when a shot presents itself there is no doubt as to whether they can make that shot!
