Hull-Mounted Fishing Sonar

HD860 Single & Dual-Beam Sonar

High-resolution searchlight sonar with stabilized transducers available in multiple soundome sizes and frequencies

Unbeatable Bottom Differentiation

WESMAR's HD860 solves the tough challenge of fish detection close to the surface, mid-water, and close to the bottom. The stabilized transducer allows you to stay on the fish and improve your catch even in rough seas.

Active Stabilization

On the HD860, the stabilization gyro is in the soundome, so when the transducer moves, the gyro senses that movement and corrections are made in the exact direction the transducer is pointing, keeping the sound beam on target. The WESMAR gyro runs 100% of the time. Other sonars have the gyro mounted on a bulkhead, making the stabilization less accurate.

Digital Link

Long cable runs are always subject to noise and decreased sonar performance. WESMAR's digital link between the sonar electronics (near the transducer) and the computer console in the wheelhouse operate noise-free for maximum sonar performance.

Searchlight Advantage

No sonar has better directivity than WESMAR engineered transducers. The entire transducer surface area points in the direction of the fish in a sharp narrow beam. Dispersed fish and hard-to-mark fish are detected clutter-free.

Stabilized Down Sounder Mode

In rough seas, the HD860 in the down sounder mode will keep the sound beam where it should be: straight down. Fishing in ice? Raise the transducer inside the sea chest out of harms way, and the sonar keeps running. It can be locked down for a reliable stabilized picture with zoom.

Available with 6, 8, or 10 inch stabilized soundome
