How to use sonar - There is a float on sonar cable, so you can put the sonar directly into the water.
- The product includes a bracket for fixing. With this bracket, you can fix the sonar on the bottom of the boat or on a stick. After the sonar is fixed, the angle can be adjusted. So the fish finder can not only detect the depth vertically, but also the horizontal distance.
- If you want to do ice fishing, please install the sonar in the handle as shown in the picture.

Notes - Please do not try the fish finder ice at the places shown in the picture. If the water depth is too shallow or the bottom surface is too smooth, the sonar will not work properly.
- If you use portable fish finder for kayak fishing, please keep moving speed less than 5mph. If the speed is too fast, the detection angle of the sonar is prone to tilt, resulting in inaccurate results.
- If you use the handheld fish finder in ice fishing, make sure there are no gaps or snow between the sonar and the ice layer. (Water is OK)
