Description

Upgrade your SoundTrap ST300 housing to the 1000m depth rated version.

This upgrade consists of fitting your SoundTrap pressure neutral housing. This housing enables deep deploys by means of a diaphragm which equalizes pressure across the SoundTrap housing. Note that this housing takes bit more maintenance and care than the regular housing. To avoid damage you must ensure the mineral oil is always topped up and that fasteners are not clamped around the center of the recorder. See the user manual for more details.
