Powerful and fast-scanning sonar. Noise-free presentation and an accurate image of fish and seabed conditions. Compact hull-mounted unit that quickly and reliably scans around the vessel within a user-defined sector, with an adjustable tilt angle.
“Yes, the sonar is excellent for both herring and mackerel—but it really shines with mackerel. We’ve had cases before where we couldn’t detect mackerel on sonar at all, but with the CH-600, they appear clearly and precisely.”
— Svein Arne Hansen, Captain of Havbris

The CH-600 / CH-500 is a high-performance scanning sonar that rapidly sweeps around the vessel within a user-defined sector and adjustable tilt angle. At the maximum 24° beam width, it can scan a full 360° in just a few seconds. A powerful motor rotates the transducer element at high speed, delivering a near real-time sonar image.
The transducer includes a high-quality motion sensor that compensates for roll og pitch. This is critical for delivering a stable, noise-free sonar display with accurate echo presentation in all conditions.
This sonar line is offered as two models, CH-600 and CH-500. The CH-600 is a dual-frequency sonar, while CH-500 is a single-frequency sonar. CH-500 is also available in 150 kHz or 180 kHz version. Both models are well suited for smaller vessels.
The CH-600 / CH-500 is an extremely fast scanning sonar—often referred to as a step sonar—that can scan a full 360° in seconds. Beam width can be adjusted to 6°, 12°, 15°, 18°, 21°, or 24°. During search operations, the beam is typically set to the widest setting (24°) for maximum area coverage. Once a target is detected, narrowing the beam down to 6° provides clearer echoes and superior target separation.
The CH-600 operates simultaneously on two frequency bands—choose between 60/153 kHz or 85–215 kHz. Both sonar images are shown on the same screen, with an optional overlay mode that allows the higher-frequency image to be layered on top of the lower-frequency view, perfect for combining detailed and wide-area information in a single display.
