Mariner’s Eye 3D Settings

To access additional settings or options from the Mariner’s Eye 3D screen, press MENU. The
options and additional settings are the same as the Mariner’s Eye screen (page 12), with the
exception of Colors:

Colors —choose between Normal (Default), Water Hazard, and All Hazard. The Normal setting
shows the land as seen from the water. The Water Hazard setting indicates shallow water and land
with a color scale. Blue indicates deep water, yellow is shallow water, and red is very shallow. The

Water Hazard setting indicates land in green and brown, and the All Hazard setting uses the same

color scale, but shows land as dark red.

Safe Depth—adjust the depth at which red indicates shallow water. This also changes the global
Safe Depth setting as it applies to the Auto Guidance feature. See page 38 for more information.
