Portable fish finder deeper Smart Sonar CHIRP+3 Wi‑Fi — castable wireless sonar, max depth 100 m, cone angles 47°/20°/7°, Wi‑Fi, GPS/GLONASS

deeper Smart Sonar CHIRP+3 is a castable portable fish finder designed for shore and from-boat use. The device uses CHIRP frequencies (100 / 240 / 675 kHz) and three cone angles (47° / 20° / 7°) to detect fish and structure from 0.15 m down to 100 m. The housing is made of ABS, is waterproof, and the unit operates in temperatures from −20 °C to 40 °C. Built-in Wi‑Fi provides a wireless connection up to 120 m and integrated multi-GNSS (GPS, GLONASS, Galileo, BeiDou, QZSS) enables mapping and positioning. The rechargeable 1300 mAh Li‑Ion battery supports fast charging (5 V, 1.5 A). The package includes a USB cable, pouch, bolts, night cover and a quick start guide.

Advantages

The deeper Smart Sonar CHIRP+3 combines three CHIRP frequency bands and interchangeable cone angles to deliver detailed returns at different depths and resolutions. Its waterproof ABS construction and wide operating temperature range ensure reliable performance in various weather conditions. Integrated Wi‑Fi and multi‑GNSS support mapping and accurate positioning without additional accessories. The built-in Li‑Ion battery with fast-charge capability offers convenient recharging and extended use between charges.

Suitable for

• Shore fishing where castable wireless sonar is required
• Small boat or kayak fishing for mapping and fish detection

How to use

Charge the unit using the included USB cable until the battery is full, then install the deeper app on a compatible smartphone or tablet. Activate the device and enable Wi‑Fi on your mobile device to connect to the sonar. Cast the sonar into the water and monitor live sonar returns and maps in the app; select the appropriate frequency and cone angle in the app settings to match depth and target detail. Use the GNSS features to save waypoints and map bathymetry while moving along the shore or from a boat.

Recommendations

For reliable wireless connection, maintain a clear line of sight between the sonar and the mobile device where possible and keep the device within the stated Wi‑Fi range. Follow local regulations for battery disposal, as the unit contains a lithium‑ion battery.
