“Over 50 years of Sonar Experience”

SonarPhone Awarded Patent #9,408,378

Minneapolis MN, Vexilar, The world leader of WiFi sonar technology has just been issued U.S. Patent #9,408,378 for their innovative SonarPhone T-POD design that houses an extremely portable yet powerful WiFi sonar transmitter that sends a sonar signal to a smart device. Introduced three years ago, SonarPhone has swept the world with over a million SonarPhone apps installed into smart devices around the world.

“We at Vexilar understood ultra-portable WiFi sonar is the future and why we were the first to create this ultra-portable technology based on WiFi,”  stated Tom Zenanko, Hall of Fame Angler and creator of the Sonarphone T-Pod design.  “My experiences with sonar technology from working at Vexilar for 17 years and 30 years as a professional angler gave me a unique insight into designing the SonarPhone T-POD concept.  The round floating “wireless sonar balls” have some serious performance issues if you try to move them in the water. I knew the round design was not practical for giving a stable sonar signal while fishing in a real world scenario. The design needed to have the ability to be pulled behind a kayak or pulled though moving water without rolling.  Think of what happens when you pull a round bobber through the water, it rolls on its side…  This is not an option with sonar as the transducer must be as stable as possible and also stay at a 90-degree angle to the bottom.  The Sonarphone T-POD also called the SP100 is designed to be stable in waves, or current which allows the superior WiFi technology of the SonarPhone to perform even better.”
