LUCKY Fish Finder

This is a fish finder.
Used once. Operation confirmed. No problems.
Below is from the internet:
Reliable even if dropped, with a rugged outdoor case. Not only is it colorized, but the sensor power has been increased by 30% and the circuit has been made highly sensitive. The search software has been upgraded with high-speed scanning across a wide band. It can search vertically and horizontally with a depth of 100m and high sensitivity adjustment. The fish finder (fish detector) has been further upgraded in performance and is newly released!! It was also featured on a Fuji TV program, and in Tokyo Bay, it caught 98 horse mackerel in just one hour! Also recommended for professional use!! It can measure depths up to 0.6 to 100m, and can detect water temperature (air temperature), bottom shape, and three layers of fish schools (large, medium, and small). This feature has a maximum detection depth of 100m and real-time graphic display, making it one of the smallest and lightest in the world!! It features a waterproof, wide temperature range, and drip-proof structure, making it the latest pocket fish finder with a depth gauge, designed by fishing experts. It displays the location of fish schools and the bottom condition in real-time graphics. It detects fish schools and depth and sounds an alarm. It can be used in any fishing spot, including rivers, ponds, lakes, and the sea, as well as from docks, under bridges, on boats, small ships, canoes, and kayaks. It also works on frozen surfaces because it is a float type!! If you have a fiberglass, vinyl, or aluminum boat, just place it on the bottom of the boat!! With the sensor angle adjustment function, it can search not only vertically but also horizontally. It can measure the depth of fish, adjust sensitivity and depth, and has a zoom function for flexible searching.
With these features, it's the smallest and lightest color model!!
