Its 3.5-inch display offers a resolution of 480 x 320 pixels, providing clear images of what's underwater thanks to its Chirp sonar technology.

The resolution, while decent for its size, may not be as sharp as higher-end models, which could affect visibility in bright sunlight. Additionally, while the unit is rated IPX7 for water resistance, some users may want to ensure proper installation and care due to its sensitive electronic components. The device runs on lithium metal batteries, so battery management is essential to avoid running out of power during long fishing trips.
