How to record DAT Trails Log

Humminbird HELIX models


You can record freely as you go about your day! For best sonar log recording, we suggest you keep your speed under 6 knots, although maximum logging speed may vary depending on which device you are using; perform a grid pattern where the distance between tracks is no more than 50 meters /150 feet; and save about every 30 minutes to reduce any risk of loss.

Note:  Please update the HELIX software to version 1.4 before recording sonar logs.
