Mercury Remote Head Applications Technical ROV'S Software   Although the Mercury is the smallest High Resolution sonar in the world, there are some small ROV's which require the sonar transducer and electronics to be separated to ease installation and not affect the ROV's performance. The Mercury Remote Head was designed to enable the Mercury to be used on vehicles such as the Videoray, where the electronics can be inserted into an extended Videoray body, or the Outland ROV. The benefit - The Sonar head can be well positioned to get a clear view of the surroundings, whilst the electronics can be safely inserted within the vehicles pod, or within its frame.
