SIMRAD SN90
Wide bandwidth sonar for trawlers
The new and revolutionary SN90 is the latest development from SIMRAD.
The user will get full control over the setting of the seine without having to care about retracting the hull unit. The SN90 transducer is installed without a retractable hull unit to the side of the keel facing the purse seine.

The SN90 also has an inspeccion beam that can be trained to any position horizontaly and vertically.
The isnpeccion bean will give a detailed echogram where information of biomass, fish size and behaviour can be monitored.
The SN90 is designed to give full control during purse seining and to inspect and analyze a school before setting the net. The transducer is mounted to the side of the keel and protected from the purse wire during setting. The pencil shaped inspeccion beam can be used to analyze a school before setting the net without passing over the school thus avoiding the school to disperse

The SN90 has a 160 degrees fan that is tiltable from 0 down to 90 degrees. This will enable to see the purse seine during the whole setting of the net.
Also, the SN90 has a narrow vertical bean.
Operational frequency band from 70 to 120 kHz making the SN90 ideal for Mackerel and Tuna as well as Herring.
