Installing the transducer using a hull unit
A hull unit may be used to lower the ES18 transducer into the water for use. When
not in use, the transducer is retracted into a protective installation trunk. A hull unit is
commonly used on sonars.

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.
Note
Several 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.
