## Description

SonarPhone by Vexilar transforms your smartphone or tablet into a fully functional touch screen fish finder rivaling costly sonar systems. With a dedicated WiFi transmitter, it works independently of cell phone coverage, allowing usage anywhere worldwide. Choose from portable or boat-mounted transmitter options — the ultra-portable T-POD, the permanent T-BOX, or the portable T-BOX with battery pack. 

The app supports 17 languages and features automatic ranging, depth and temperature indicators, audible alarms, and a multi-color display. Users can demo all features without a transmitter. Each purchase includes a bonus neoprene armband for safe, easy phone access. Specifications vary per transmitter model, offering depth ranges from 120 to 240 feet and high-speed data transmission up to 100 Mbps.
