  • Page 29: Ice Fishing

    Ice fishing It is usually difficult to find the appropriate fishing position when doing ice fishing, yet this product (NAKI8850B) will make things easy. To achieve the best performance for ice fishing, it is highly recommended that you cut a hole through the ice and place the Fish Finder directly in the water.
  • Page 30 1. Find an appropriate position on the ice surface. Clear away snow to expose the ice surface, making sure the surface is smooth. 2. Spray a small amount of liquid water on the ice and set the sensor on the water allowing the unit to freeze to the ice.

    electronics. Boat fishing Boat fishing There are three ways of using the Fish Finder from a boat: 1. Toss the sensor into the water as said in the previous instructions. 2. “Shoot-Thru” the hull of a boat: coat the hull face below of the sensor with Vaseline and press it against the hull bottom with a twisting motion.
  • Page 32 methods do not work on all hulls and you may have to place the sensor directly in the water for proper operation. Note: T he “shoot thru” capability of the Fish Finder does not apply to all boats. The hull must be made out of solid fiberglass, or a maximum of 3 mm aluminum, and be in direct contact with the water, with no air pockets.
