Full spectrum sound that "fools" the wariest critters around!

FREQ Wins Four of Nine Categories in West Texas Big Bobcat Contest!

Just weeks after launching, FREQ, the Ultrasonic Game Call, was used by four of the nine category winners in this past Saturday’s (January 13, 2024) West Texas Big Bobcat Contest. It is estimated that between 40 and 50 of the 521 teams entered were using a FREQ Call, which is less than 10%. Yet, 44% of the category winners used FREQ’s full spectrum sound to claim their victories.

FREQ inventor Gary Roberson said, ‘We are thrilled with the fact that so many teams put their trust in FREQ, especially when we literally just started selling the calls a few weeks ago. Our sales have been brisk, and we expect that a lot more teams will be using FREQ Calls in the next event.’

Phil Lyne, Cotulla, TX

On a ranch where attracting coyotes had been challenging for a couple of years due to night hunting pressure, we achieved remarkable success with the FREQ. We called up 11 coyotes and killed 10, all within a 100-yard range. Despite their cautious nature, the FREQ proved to be a game-changer, as without it, we likely wouldn’t have killed more than two coyotes.

Ultrasonic Game Call
$1,999.00

Introducing FREQ™, the world’s first ultrasonic, full-spectrum electronic game call. It features two unique True Cast speakers, one of which produces lower frequency sound at the end of the spectrum that humans can hear while the other produces sound well into the ultrasonic end of the sound spectrum. Sound that humans cannot hear but that animals rely on to communicate. Sound recorded on state-of-the-art recording equipment designed specifically to capture both low and high (ultrasonic) frequency sound. Crafted by the renowned game calling expert, Gary Roberson, this revolutionary product is the result of years of meticulous research and development. Most importantly, it absolutely works!

FREQ Sound Range Chart

Experience the Power of Ultrasonic Calling

FREQ is the first ultrasonic game call. FREQ produces ultrasonic sound that reaches up to 50 kHz compared to ordinary e-callers, which produce sound that reaches just 12-18 kHz.

The Power of Ultrasonic Technology
Ultrasonic Revolution
Revolutionary Ultrasonic Technology makes FREQ™ the most effective and realistic electronic game call ever made.
For years, game calling expert, Gary Roberson (Co-Owner of FREQ), has observed animals silently communicating. Eventually, curiosity got the best of him and he decided to do some research. That’s when he discovered ultrasonic sound and the fact that virtually all animals hear much higher frequencies than humans. Humans can hear up to 20kHz, (an ability that diminishes with age). Compare this to a coyote, for example, that can hear up to 44 kHz. Or a bobcat that can hear up to 64 kHz! And rabbits emit sounds that are 50+ kHz.
Overcoming E-Caller Limitations
The E-Caller Limitation
You’ve also, no doubt, noticed that predators and game animals are often very cautious when coming to a call and often hang up at a safe distance. This is not just their wary nature, it’s also because of the limitations of your e-caller.
But, Roberson discovered that you cannot simply transform existing recorded call sounds into full spectrum, ultrasonic call sounds. Instead, it meant using state-of-the-art recording equipment and recording all of the needed sounds. And then, building a speaker and electronic circuitry capable of playing ultrasonic sound. It meant totally reinventing electronic game calls. Which is exactly what Gary did! But it did not happen overnight. Finally, after several years of product development and field testing, FREQ™ Ultrasonic Game Calls was born!
Unparalleled Results with FREQ™
Game-Changing Results
Stunning results: 50% to 100% more stand success, far more aggressive responses, fewer hang ups and warning barks.
Even Gary was shocked by the remarkable animal reaction he got to his new FREQ™ Ultrasonic Caller. His stand success more than doubled! The aggressiveness of the responses was immediately noticeable and off the charts! Animals came running in without hanging up. He almost never heard warning barks anymore. The range of the call was almost unbelievable, even with a crosswind. Birds like hawks, crows, and ravens that rarely came to ordinary e-call sounds frequently responded. And, most notably, he was able to harvest predators on property that had been heavily hunted and many of them were wily old, toothless critters that had been previously unkillable. But, when you think about it, this really shouldn’t come as a big surprise. For the first time ever, thanks to FREQ™, you can truly emulate the real sounds of both predator and prey. Before FREQ™, you were using only a partial range of their sound and nothing in the high frequency end of their range. To the animals you were really speaking a foreign language, or at least a broken language. Not anymore!
Technical Mastery of FREQ™
Technical Mastery
FREQ™ is capable of playing sounds up to 50kHz. This compared to other e-callers that all peak out at 12 to 18 kHz.
Recorded with ultrasonic recording equipment and played through exclusive TrueCast™ speakers, FREQ™ Ultrasonic Game Calls feature a wide array of real animal sounds. These are captured with special ultrasonic recording equipment and then played back through FREQ™’s two premium TrueCast™ speakers (one audible, one ultrasonic). This exclusive combination gives you full spectrum sound and the ability to call game with never-before-achieved realism.
