Operating at 85KHz, the CSH8L MK2 is a midfrequency Sonar; its narrow beam width coupled with its  enhanced target identification capabilities make it ideal for searching near the vessel or in shallow waters.

Scan three football fields or further around your boat - in every direction.

The transducer of a scanning sonar consists of many elements to transmit the echo in all
directions simultaneously without rotating the transducer. The echo is redrawn on the
display instantaneously according to the latest feedback from the transducer. It’s truly like having an underwater Radar!

Operating at 85 kHz, the CSH8LMK2 is considered a mid-frequency Sonar. Its narrow beamwidth coupled with its enhanced target identification capabilities makes it ideal for searching near the vessel or in shallow waters. Fish and bottom echoes are clearly separated and baitfish are more easily tracked. With automatic tilt scanning as a standard feature, the CSH8LMK2 is suitable for both midwater trawlers and purse seiners.

What is Scanning Sonar?

The transducer of a scanning sonar consists of many elements to transmit the echo in all directions simultaneously without rotating the transducer. The echo is redrawn on the display instantaneously according to the latest feedback from the transducer. Because this sonar scans quickly, it greatly improves the fishing operation, especially when searching for/following fast swimming fish.

Extremely Quick Scanning Speed

The CSH-8L MARK-2 completes a scan within 0.54 seconds/scan while the conventional PPI sonar*1 takes 32 seconds to train full circle under the same range/conditions*2.
About 60 times more information is provided compared to a PPI sonar.
Fast scanning lessens the chance of missing a small change in underwater conditions. This is especially helpful when range and tilt require frequent adjustment while fishing, offering no frustration on redrawing time.
*1 CH-250 PPI sonar, training at 6° steps.
*2 Based on 400 m range in combination display mode.

No Blind Area

Scanning Sonar shows the actual situation 360 degrees around the vessel and gives all the necessary information as needed. No more blind areas to consider, allowing the operator to concentrate on the tilt, range, fishing area, etc.
