Product specification Portable fish finder deeper Smart Sonar PRO+ 2 sonar 675 kHz, 100 m range, 65×65×65 mm, Li‑Ion 950 mAh

The Deeper Sonar PRO+ 2 is an improved castable sonar device with three beam frequencies, enhanced imaging clarity, upgraded GPS performance, longer battery life up to 9 hours (depending on use), and scanning depth up to 100 m. It connects to your smartphone or tablet via its own Wi‑Fi signal so you can cast, map and view underwater structure and fish targets from boat, kayak, shore or ice.

Advantages

The three beam frequencies (100 kHz wide, 240 kHz mid and 675 kHz narrow) let you cover large areas, focus on hotspots and obtain detailed target separation. Built‑in GPS enables on‑the‑water bathymetric mapping from boat, kayak or shore. The unit creates its own Wi‑Fi connection (no cellular data required) and offers reliable connectivity up to cast range, scanning to depths of 100 m. Target separation is excellent for identifying individual fish and tracking small lures when vertical jigging. The compact, cordless design works for kayak/SUP, small boats, shore and ice fishing without additional transducers or cables.

Key specifications

• Beam frequencies: 100 kHz (47° wide), 240 kHz (20° mid), 675 kHz (7° narrow)
• Maximum scanning depth: up to 100 m
• Battery life: up to 9 hours (depending on usage)
• Built‑in GPS for on‑water mapping
• Connectivity: device‑generated Wi‑Fi (no cellular data required)
• Target separation: 1 cm (narrow), 2.4 cm (mid and wide)

How to use

Power on the Deeper Sonar PRO+ 2, open the Fish Deeper™ app on your smart device and connect to the sonar’s Wi‑Fi network. Cast the device from shore, dock or boat and reel in slowly to start sonar scanning and mapping. For lake mapping with GPS, cast and retrieve while underway from a boat or kayak, or cast and reel from the shore; maps are saved automatically to your Fish Deeper™ account. For ice fishing, drop the sonar into the hole and view live sonar returns on your device. Adjust beam frequency as needed to switch between wide-area searches and high‑detail scans of a target.

Recommendations

Use the wide 100 kHz beam to locate fish-holding areas quickly, switch to 240 kHz to inspect promising spots, and use 675 kHz for the most detailed imaging. Keep your device charged and maintain a clear line of sight between the sonar and your smart device for optimal Wi‑Fi connectivity.
