Vexilar SP100 SonarPhone w/Transducer Pod

The Vexilar SP100 SonarPhone with Transducer Pod is the world's most portable Wi-Fi fishfinder, designed for anglers who demand mobility without sacrificing sonar capability. This ultra-compact system pairs a self-contained, rechargeable transducer pod with smartphone connectivity, enabling real-time sonar imaging from virtually any fishing platform—boat, shore, kayak, or wading position. The SP100 transmit range extends to 100 yards, providing reliable coverage across most inland waters and shallow saltwater environments.

The transducer pod's hydrodynamic shape tracks straight in the water at speeds up to 5 miles per hour—critical for maintaining stable sonar returns during trolling or drifting presentations. Battery endurance reaches 4 hours per charge, sufficient for a full morning or afternoon session without requiring mid-day recharge. The 1-pound weight and compact 9 × 3 × 10 inch dimensions allow the system to fit into a tackle bag alongside standard fishing gear, eliminating the bulk penalty of traditional hardwired fishfinders. Wi-Fi connectivity bridges the pod and smartphone without cumbersome cables, enabling sonar monitoring from multiple devices simultaneously.

This system serves serious anglers targeting structure and suspended fish in lakes, reservoirs, and coastal shallows where portability determines success. Bass fishermen, walleye hunters, and saltwater sight-casters benefit from the ability to deploy and reposition without deck space constraints. The SP100 bridges the gap between smartphone convenience and dedicated sonar performance, addressing the field need for real-time bottom mapping and fish detection on platforms where conventional fishfinders cannot be mounted. Vexilar's reputation for sonar accuracy in freshwater applications translates directly to this compact platform.
