That’s the Wrong Color Palette
by Brad Wiegmann
How many times have you changed the color palette of your sonar unit to see the sonar image better?
Most readers would probably say, “Never.” Some don’t even know they have the option to change the colors displayed on their unit. But by changing the color palette setting anglers can often enhance sonar returns and see the sonar screen better.
The options of color palettes depend on the brand of sonar unit you have.
Last year Garmin came out with Vivid Color Palettes for ClearVu, SideVu and LiveScope sonar.
Lowrance and Humminbird have several color palettes available in all models. Most sonar units allow the angler to change the color palette for each panel/window.
Marine electronic companies set the default color palettes during research and development of a sonar unit. The engineers test color palettes in all scenarios, however, it’s impossible to preselect what might be best for where and when you are fishing.
Reasons to change the preset color palette include amount of sunlight, bottom composition, cover, structure, sunglasses and eyesight. You can’t change eyesight; everyone sees colors differently which explains why one palette looks good for one angler and not another angler. Sunglasses create similar problems as polarized or colored lenses will affect how a screen is viewed.
When bright sun or glare off the screen make viewing a sonar image difficult, or even impossible, readjusting the position of the unit and changing the color palette to a brighter color will make viewing easier. On cloudy, overcast days or at night use a middle range color palette for best viewing.
On reservoirs or rivers with soft bottom composition, the unit’s sensitivity will have to be increased while it should be decreased if you’re over a hard bottom. The increase or decrease should be adjusted in 2D traditional sonar, side imaging, down imaging or live imaging sonar (LIS); in addition to selecting a brighter color palette like green or yellow.
Adjusting the settings will help differentiate bottom hardness and return strengths of bottom composition, cover and structure.
Color palette selection for LIS is based on a black background allowing for anglers to see the smallest detail. Most anglers using Garmin LiveScope use the moss color palette while Lowrance ActiveTarget and Humminbird MEGA Live prefer the amber color palette for seeing game fish, baitfish, cover and structure.
What color palette is best also depends on a person’s personal preference. In general, the default setting should be changed according to the lake or river an angler is fishing and changed throughout the day if necessary for better viewing.
