SonarPeak's sonar reaches up to 328 feet below the surface, giving you full coverage across the vast majority of freshwater and saltwater fishing environments. That's plenty of depth for lakes, rivers, bays, and open ocean.

Absolutely. SonarPeak is engineered to perform in both environments. Its detection system auto-adjusts to changing water conditions, so you get accurate readings whether you're on a mountain lake or a coastal bay.

On a full charge, SonarPeak delivers 8–10 hours of continuous operation. Activate the built-in power-saving mode and you'll stretch that even further — no mid-trip recharging, no interruptions to your day on the water.

Not even close. Wireless pairing takes under a minute and the controls are designed for instant use. Most anglers have SonarPeak up and detecting fish within minutes of opening the box — no manual required.

Yes! SonarPeak is purpose-built for multi-environment use, ice fishing included. The cold-resistant housing and reliable sonar performance hold up through freezing temperatures so you can fish confidently all winter long.

The LCD screen shows fish size and depth, water temperature, and bottom contour mapping — all updated in real time. That data helps you choose the right tackle, target the right depth, and land more fish.

SonarPeak is fully waterproof with a sealed, submersion-ready build. It handles accidental drops, heavy rain, and constant splashing without any damage — because reliable gear shouldn't stop working when things get wet.

You can use SonarPeak from anywhere — shore, boat, dock, or ice. Simply cast the sensor into the water and monitor readings from your preferred position. It's designed to fit every style of fishing, not just boat anglers.
