What’s on the Sonar Display

The 500 Series™ Fishfinder can display a variety of useful information about the

Depth - (water depth) can be set to alarm when the water becomes too shallow.

Temperature - Water surface temperature.

Timer - Elapsed time with Temp/Speed Accessory.

Distance - Distance traveled with Temp/Speed

Accessory.

Average Speed - Average speed reading with

Temp/Speed Accessory.

Thermoclines - Layers of water with different temperatures that appear at different depths and different times of the year. A thermocline typically appears as a continuous band of many colors moving across the display at the same depth.

Second Sonar Return - When the sonar signal bounces between the bottom and the surface of the water and back again. Use the appearance of the second return to determine bottom hardness. Hard bottoms will show a strong second return, while soft bottoms will show a very weak one or none at all.

Speed - If a Temp/Speed accessory is attached, the Fishfinder can display the speed of the boat and can keep a Triplog of nautical or statute miles traveled.

NOTE: Entries in this view that list (with Temp/Speed) are available if the accessory is connected
