Multifrequency - 110 to 122kHz!
On fishing vessels there are numerous sources making noise, such as propellers, generators, engines and other hydro acoustic equipment. With multi frequency from Simrad you are able to tune your sonar for maximum performance and avoid interference from own and other vessels. The multi frequency comes very handy in other situations as well; high and low frequencies have different detection ranges on different conditions and species. 360 degree coverage
The SH40 is based on the same advanced technology as other Simrad omni directional sonars. This means that you have an instant full circle coverage and not have to wait for the single beam to rotate 360 degree. The PI system can be interfaced to anySimrad sonar and give you vital information about fishing gear performance on your sonar screen. Dual beam Beam stabilization Full control
The combination of the horizontal andvertical beams display the school of fish from above and from the side at the same time. It is not necessary to go over the target to see the vertical dis- tribution on the echosounder. When the beam stabilizer is activated, both the horizontal and vertical beams will be electronically stabilized for roll and pitch. The full circle beam stays on the target independent of the vessel movement even in rough seas. Mount depth sensors on the ground gear to have full control of sinking rate and depth of your net. The PI system can receive information from up to six sensors at the same time!
