Wireless Sonar Fish Finder — Portable LCD Echo Sounder, 100m Range, 2–120ft Depth

Key features

This portable fish finder uses a 125 kHz sonar with a 90° beam to help locate fish and measure depth. The unit shows readings on an LCD display and provides audible depth alerts for clear, immediate feedback.

The wireless transducer removes long cables and supports up to 100m (328 ft) wireless operation, while the detector itself reads depths from 2 to 120 ft (0.6–36 m).

Practical use and durability

Small and lightweight, it slips into a pocket and suits boat, platform, long-range and ice fishing alike. It runs on 4×AAA batteries (not included) and works across a wide temperature range for year-round use.

Compact dimensions and low power draw make it easy to carry and set up; the unit operates on RF 433.92 MHz and consumes around 0.1W.
