Depth Range Shading
You can set color ranges on your map to show the
water depths where your target fish are currently biting.
You can set deeper ranges to monitor how quickly the
bottom depth changes within a specific depth range. You
can create up to ten depth ranges. For inland fishing,
a maximum of five depth ranges can help reduce map
clutter. The depth ranges apply to all charts and all bodies
of water.
Some Garmin LakeVü
™
and premium supplemental charts
have multiple depth range shading by default.
Red
From 0 to 1.5 m (from 0 to 5 ft.)
Orange
From 1.5 to 3 m (from 5 to 10 ft.)
Yellow
From 3 to 4.5 m (from 10 to 15 ft.)
Green
From 4.5 to 7.6 m (from 15 to 25 ft.)
