Topside Repeater (TSR) Remote Display Unit
The Cygnus Topside Repeater is a remote display unit connected to the DIVE meter with an umbilical cable. It displays the thickness measurements at the surface in real-time during the survey.

Topside Repeater with Video Overlay
The Topside Repeater can also overlay the real-time thickness measurements on to a composite video signal, displaying it on the survey monitor screen. It will also then be recorded (if there is a video of the survey), showing exact locations and the thickness measurement for future reference.

HelmetView™ Display
This is a remote display with a fixing bracket for Kirby Morgan® Helmets that have an accessory mounting point. This is depth rated to 984 ft, and designed for use in situations with extremely poor visibility and ease of viewing by the diver.
