Powerful detection performance Multiple detection modes: It has multiple modes such as traditional 2-D sonar view mode and ice fishing flasher mode, and can also adjust parameters such as frequency and scrolling speed to meet the needs of different fishing scenarios, such as accurate operation in freshwater or saltwater (even ice fishing), and clear display of fish and underwater structures. High-precision detection: It uses advanced sonar technology to accurately detect water depth, temperature, fish location and underwater terrain structure. Some products, such as the Lowrance fish finder, have a 3D terrain detection function that can turn on 5 sonar probes for simultaneous detection, and quickly depict the underwater terrain through intelligent digital modeling. It has extremely high sensitivity and accuracy and can capture subtle changes in the bottom of the water. Large detection range and depth: The detection range is wide, such as some products with a detection range of 0.6-183 meters, and the wireless connection distance is also long. For example, the wireless connection distance of Garmin's wireless fish finder can reach 60 meters, and the maximum detection depth can reach 45 meters to 55 meters, allowing anglers to easily grasp a wide range of underwater dynamics.
