Wesmar HD850 Series Sonar -
The HD850 is the combination of new technology and quality engineering, featuring a number of important new elements.
Active Stabilization-
The stabilization gyro is in the soundome, so when the transducer scans, the gyro scans with it. Corrections are made in the exact direction the transducer is looking, keeping the sound beam on target. The Wesmar gyro runs 100% of the time. Other units have the sensor mounted to the bulkhead, delaying response time.
Digital Link-
Long, interconnect cable runs are always subject to noise and low sonar performance. Wesmar's new 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 ha better directivity than Wesmar engineered transducers. One hundred percent of the transducer surface area points in the direction of the fish in a sharp and narrow beam. Dispersed fish and hard to mark fish are detected clutter-free. An Omni sonar, with a diffused beam, allows dispersed fish and fish near the bottom to go undetected.
Split Screen Mode-
Scan forward and then across the bottom. This is ideal for mid-water and bottom trawling. Head for the fish out in front and watch as they pass to either side of the vessel. Sounders only mark under the vessel and not to the sides, missing the target.
Top part forward scan, lower part profile, each have separate adjustments.
Stabilized Down Sounder-
When the seas get rough, the best of sounders lose track of the bottom. The HD850 in the down sounder mode, with active stabilization on, will keep the sound beam where it should be: straight down. Lower the hoist below the bubble layer for a ground picture unmatched by other sounders. Fishing in the ice? Raise the transducer inside the sea chest, and the Wesmar keeps running.
Linear Scan Mode-
Ideal for finding and tracking fish close to the bottom. Linear scan mode presents a forward view of the bottom not available on other sonar's. With this comes better differentiation between the bottom and fish close to the bottom. In linear sonar presentation the sweep starts at the left and moves to the right. Range is measured vertically, bearing along the horizontal. When scanning for ground fish, the bottom will mark horizontally across the screen and not a half circle.
