Our take on the Wireless Sonar Fish Finder Sensor

This is a floating spherical sonar sensor that casts out on a line and sends depth and fish readings to a phone over 2.4 GHz Bluetooth. It reads depth from about 0.6 m to 36 m (2 to 120 ft) with a 125 kHz sonar and a 90-degree beam, and the battery is rated for about 10 hours. It suits bank and shore anglers who want a cheap way to read depth and mark fish without a boat-mounted unit. Against rivals it is a basic castable sensor: no GPS, no mapping, and a 30 m wireless range that limits how far you can fish from your phone.

Questions and answers

How deep can it read?
The spec lists 0.6 to 36 m, or about 2 to 120 ft. Real readings depend on water clarity and bottom type.
Does it need a phone?
Yes. It sends sonar data over 2.4 GHz Bluetooth to a mobile device, so there is no built-in display.
How far can it be from my phone?
The listed Bluetooth distance is 30 m. Keep your phone closer than that, and expect less with interference or a wet line.
How long does the battery last?
The rated power life is about 10 hours per charge. The top half unscrews to reach the battery compartment and contacts.
Can I use it in winter?
The operating range is -10 to 60 °C. Below freezing, battery life will drop and the reading may be less reliable.
Does it have GPS or mapping?
No. It is a sonar sensor only, with no GPS, charting or waypoint features.
Where is the Wireless Sonar Fish Finder Sensor cheapest?
At Deal.ai, for $98.99, as of our latest check.
