Install Sonar

Follow the illustration to attach the sonar to your fishing line.

Select the appropriate screw mounting point based on your position above the water to keep the sonar vertical to the riverbed during retrieval.

Avoid impacting the sonar against hard objects during casting. Damage caused by such impacts is not covered by the warranty.

Range

The communication range between the sonar and the smartphone is up to 100 meters.

2. Turn on/off sonar & connect to app

The indicator light turns on in water, flashes rapidly after app connection, and the sonar powers off automatically after 5 minutes out of water.

Frequency & angle

Provides three frequencies with corresponding scanning angles. Higher frequencies deliver finer imaging with a narrower coverage angle.

Adjustable sensitivity

Sensitivity can be adjusted in the app to filter display noise.

Depth & accuracy

Minimum resolution: 10 mm. Depth: 0.3m - 40 m.

Sonar settings interface (APP)

Riverbed & Silt & Aquatic plants & Fish

A. Riverbed

When the sonar signal reaches the riverbed, it appears as yellow (Day Mode) or light green (Night Mode).

A thicker color band indicates a softer bottom, while a thinner band indicates a harder bottom.

B. Silt

If blue (Day Mode) or brown (Night Mode) echoes appear around the riverbed, this indicates the

presence of a silt layer.

C. Aquatic Plants

Echoes that extend upward from the riverbed and form continuous

structures are generally identified as aquatic plants.

D. Fish

Between the riverbed and the water surface, arch-shaped (fish arch) echoes are typically identified as fish.

Rewind & Double-tap

During scanning, swipe the sonar screen to review

previous data. Double-tap the sonar screen to define a spot.

GPS & Depth Map

Built-in GPS enables automatic 2D/3D depth mapping for clear visualization of the riverbed.

Record data & Define spots

Scan data can be recorded and replayed in the app to help identify the best fishing spots.
