Product Information
The Toslon TF520 fish finder uses a sonar beam to locate fish and show underwater obstacles, hills and holes. It is intended for carp anglers, including Zig Rig fishing, where it can help set a leader to the feeding depth of fish.
Its 4.3-inch TFT LCD has a 480 x 272-pixel, 65,536-colour display that remains viewable in sunlight and across wide viewing angles.
The unit uses 115kHz sonar with a 60-degree beam angle and has an anti-interference filter, 2.4GHz wireless radio and bottom-hardness differentiation.
The TF520 has a 300m range and reads to depths of 30m. The monitor and transmitter run from 12V supplies, while the sonar unit measures 153 x 110 x 44mm. A portable case measures 262 x 150 x 98mm and the casing has IPX6 waterproofing.
