Every system has a builder. This one has been calling coyotes for more than forty years, started by soldering his own, spent over six years running the ad agency that helped take a caller brand to #1 in America, and then built the system he actually wanted. Transcript follows.
Meet the Founder
With over 40 years of experience in predator calling and hunting technology, Sheldon Charron is the driving force behind PREYR and CallTuneAI. A seasoned innovator, Sheldon founded Enter360 Media, where he led groundbreaking e-commerce and marketing campaigns for top outdoor brands.
Industry Professional
Sheldon began building his own predator calls in the 90s using alpine cassette decks, Johnny Stewart tapes, car speakers, and gel cell batteries in insulated boxes to withstand extreme Canadian winters. In the early-to-mid 2000s, FOXPRO retained the services of Sheldon's agency, Enter360 Media, during a pivotal period in their growth. Sheldon and his in-house team provided creative strategy, product branding, and national advertising support across multiple product lines and campaigns. As a dedicated predator hunter, Sheldon also contributed field-based feedback and consulted on feature enhancements aimed at giving FOXPRO a competitive edge in the evolving market.

Proven Track Record
While leading Enter360 Media, Sheldon also built deep experience in film and television production, applying cinematic storytelling principles directly to brand building and marketing. His work spans commercials, branded documentaries, outdoor and adventure content, and long-form narrative projects developed in parallel with his agency work. This background includes writing feature-length film and television scripts, as well as producing documentary-style films such as America's Rifleman, featuring long-range shooting legend David Tubb, and The Precision Riflesmith, profiling world-record-setting gunsmith Mike Bryant. These storytelling foundations continue to inform Enter360’s approach to high-impact creative, product marketing, and audience engagement.
Around the same time Sheldon and his team spent seven years helping build SWFA, the riflescope company, running their marketing, catalogs and technology, that resulted in a 40x increase in sales in 18 months, expansion into brick and mortar and the creation of their iconic SuperSniper riflescope brand that is the cornerstone of their business today.

Sheldon has produced and directed mainstream film and TV, firearms industry documentaries and outdoor shows. The phone became a powerful camera. Good enough for b-roll and social content, and eventually was used in movies and television. But there was never an app that fully took advantage of what it could do, with the features hunters needed, while keeping it simple enough to use in the field when the adrenaline hits and there's no retake. So he built his own.
