Yes it works well for ice fishing, although you must drop the transducer below the ice in order for it to read depth accurately. Battery life is fantastic even in below zero temperatures.
Can you mount the transistor on the side of a Boat or Kayak?
Yes! you can easily fix the transducer to the hull of a kayak (the outside). As long as the transduces touches the water it will work perfectly.
Once cast out how much area will it cover?
When you cast out the transducer into the water, it will detect the 45 degree beam angle below the transducer underwater.
How far can the Fish Finder be cast?
The transducer comes with a 25ft cable as standard in the package.
Can you use it the Fish Finder at night?
There is backlight built in the handheld fish finder, so it will display the data clearly at night on screen.
