Underwater Display

The OTAQ Underwater Display is a robust, 3000m rated* versatile subsea solution that can display serial data from a wide range of onboard sensors and external OTAQ and third party sensors.

Activated and viewed by ROVs and divers, serial data is viewed via the low power, high visibility LED array, the Underwater Display can be mounted in any orientation with connected sensors set to zero either via command through the RS232 or RS485 communication line or by using a OTAQ OptoCom light communication module.

The Underwater Display is mounted on endplates while the viewing cylinder including the LED array can be rotate in 45° degree increments to allow for the best view positioning. The high durability viewing cylinder is further protected by stainless steel bumper rods.

Available with work enabling onboard options such as a pressure sensor and a pitch & roll sensor, the Underwater Display is an integral part of OTAQ’s range of Gyro Survey Frame and Deployment Frame solutions which include s ubsea batteries, switches, integrated temperature, depth and orientation sensors and high precision metrology stabs.
