On a trawler, the forward looking transducer is mounted on the vessel’s bow, well protected against acoustic noise from hull, machinery and propellers. The high resolution and long range allows you to detect and investigate single fish and schools - even those close to the bottom - from a distance of several hundred meters.
On a purse seiner, the side looking transducer gives you full control over the setting of the seine. There is no need to retract the transducer using a large hull unit. A large horizontal coverage area provides you with the full overview.
