Transducer shaft sleeve |
The retractable hull unit is more expensive than a blister, but on vessels with a hull where it is difficult or impossible
to install a blister, it may still be a cost effective solution.
Vessels without a keel and with a wide, flat bottom is an example where a retractable transducer using a hull unit can be
the only acceptable method for bringing the ES18 transducer below the boundary layer.
NoteSeveral Simrad sonars are provided with hull units of various sizes. Any one of these hull units can be redesigned for use with a ES18 transducer. If this is a realistic option, call your dealer or Kongsberg Maritime for advice.
