STDC LLC's New Device for Precise Mountain Hunting


Sniper Tools Design Company, LLC -- a Colorado-based, veteran-owned small business and owner-operator of the Mountain Shooting Center in Utah -- just introduced its new Angle Cosine Indicator-HUNTER for sportsmen who traverse the mountains in search of trophy big game.

The ACI-HUNTER is a small, rifle-mounted device to help hunters quickly calculate the "gravity" distance to target, as opposed to the "line of sight" distance provided by laser range finders. This is a little understood area of long distance shooting in the mountains, according to a recent press release.

"Some hunters really don't realize how the science of gravity and math impact the world of external ballistics when shooting up or down mountainsides and across deep valleys," said Professional Hunter Bryan Martin, owner of Asian Mountain Outfitters, a respected international guide for hunters who pursues elusive trophy big game on mountainsides above the tree line. "At extreme angles and distances of hundreds of yards, this typically results in disappointing missed shots and loss of trophy animals."


So Martin approached his longtime friend Ward Brien, a US Army veteran and President and inventor of the Angle Cosine Indicator for a solution.

The compact ACI-HUNTER is precision manufactured in the USA from aerospace grade aluminum alloy weighing less than an ounce. It's waterproof, ruggedized and impervious to hot and cold temperatures. The ACI-HUNTER is completely mechanical, needs no batteries and works in any climatic condition or altitude where the most sought after big game trophies roam, according to the press release.

It mounts to the main tube of your rifle scope or Picatinny scope base rail. This ACI is intuitive - displaying angular measurements on the left side and the corresponding angle cosine on the right side of the unit. The device requires minimal training and only a command of basic math skills to make quick, accurate shots by referencing a handy pre-made range card attached to your rifle stock, according to the release.

You can also incorporate ACI measurements into a ballistic calculator for even more precise ballistic calculations by entering the angle or cosine.

The ACI-HUNTER is the newest design of the company's original, battlefield proven ACI-Military issued to Special Forces and NATO personnel throughout the world.

"The Sniper Tools Design team is excited about expanding into the hunting community," said Brien. "Helping hunters become more proficient marksmen also means more ethically harvested animals and fewer wounded or lost trophies. The ACI-HUNTER will provide sportsmen with the same dependable range correction performance as their military counterparts experience with our MIL-SPEC ACI equipment."

The ACI-HUNTER retails for $137.00.
