Wireless & Wired The fish finder supports wireless operation of maximum 100m and water depth detection of maximum 45m for wireless mode. The depth detection range can be up to 100m when you switch to cable mode. A 25ft extension cable is included, and the wired transducer comes with a plastic float against fish bite. The hand-held fish finder is rechargeable.
Water depth & fish location: you can easily know the water depth when the sonar transducer is completely in the water. If you have the sonar transducer attached to the hull of your boat or kayak, you know the water depth distribution of a specific area when the boat or kayak moves. It will be easier to find a good position for fishing. Meanwhile, you can also know the approximate fish location and fish size.
WATERPROOF:The handheld fish finder is waterproof in the rain. No need to worry, the splashes will no longer damage the screen. Although the hand-held fish finder fell into the river or lake, the fish finder floated on the surface of the water. You only need to put the portable fish finder in the fresh air after fishing to avoid water vapor in the display due to the temperature difference.
SONAR CONVERTER WITH ATTRACTIVE LAMP The sonar transducer operates at 125KHz at a 90 degree beam angle. The wireless fish finder alerts when the sonar ball detects fish or schools of fish. In addition, you will receive an alarm when you detect shoals. You can put the transparent replacement cap on the sonar ball that glows in the dark, so you can easily see where the sonar ball is located when night fishing.
IDEAL FOR FISHING LUCKY Ice Fish Finder is widely used in ice fishing, kayak fishing, boat fishing and shore fishing. The fish finder and its sonar converter can work continuously for 5 to 6 hours after full charge. Once the battery saving mode is activated, it can even work for more than 10 hours.

With a portable fish finder, you can determine the water depth, fish location and objects on the ground (rocks, kelp) in real time. The sonar sensitivity of the portable fish finder can be adjusted, so you get accurate detection information even in cloudy water quality.
This fish finder is an improved model of the popular portable fish finder LUCKY 1108. Compared to the normal model of the portable fish finder LUCKY the ice fishing version has a handle for installing the sonar, which makes it easier for you to use the fish finder on ice. At the same time, the performance of the sonar has increased by 30% and it can penetrate ice to detect fish.
The portable fish finder uses 4 AAA batteries as electricity. In energy saving mode, the fish finder can work continuously for more than 6 hours. We believe that the portable ice fishing model finder is a good partner in your fishing life, whether you are a beginner in fishing or an experienced hobbyist. We offer a one-year warranty.
High performance sonar The detection depth range of the sonar is 3 to 328 feet. The detection angle is 45 degrees. These parameters are the same as the normal LUCKY portable fish finder. However, the scan frequency of the sonar of the ice fishing model has increased by 30%. So fish can also be detected under the ice on ice.
Der tragbare Fischfinder LUCKY des Eisfischermodells kann nicht nur perfekt auf Eis erkennen, sondern auch zum Bootsfischen (Pontonboot, Kanu, Schwimmrohr, Kajakfischen) und Nachtfischen verwendet werden. When you attach the sonar to the bottom of the boat, the fish finder can detect not only vertically, but also horizontally.
