It is possible to fishing either in clear water or in turbid by adjusting the sensitivity of the handheld fish finder. You will never miss fish or fish schools because of the fish alarm function built in the handheld fish finder.

◆ Casting Performance Improved: The blue housing for the portable fish finder sonar is not only improved performance in ice fishing, it also helps you to cast the sonar transducer further than it used to be. No matter it is shore fishing or kayak fishing, you will have better understanding of the fish distribution in that area.

Find Accurate Fishing Location: Wireless fish finder will catch the action of the fishes, and show information on the kayak fish finder. You can use it to track the right place, to confirm the location and depth of fishes.

Ice sonar transducer would work automatically as soon as it touches the water.

LCD Depth Display: The wireless fish finder can detect and display water depth, rocks, short & tall weeds and bottom contour. It also displays approximate fishes location. You can freely choose water depth measurement unit either in meter or in feet. Fish alarm setting will alert you when schools of fish appear.
