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.’
