Boomer Stelmach introduces us to Sonar Phone which puts fish-finder technology within reach of everyone – dock and shore anglers, kayakers, waders, potoon boaters – starting at only $130. The castable TPod transducer is the size of a baseball. Sonar Phone is brought to you by Vexilar and their decades of experience in the sonar industry. Because it operates on WiFi, multiple users can read the same transducer. Also, it was revealed at ICAST that Sonar Phone can be used in conjunction with GPS software such as Navionics. User friendly, budget friendly, super portable and super cool!
