VideoRay can be used with Trackpoint positioning systems.
Purchase the electronics bottle (200 Series) and transponder (RM90V) from Applied Acoustics Engineering (AAE) in the UK. Make sure to tell them that this is for an existing ORE installation and being set up for a VideoRay. This is the best set up because the transponder will have clear line of ping with the responder beacon. If the transponder and the electronics bottle is one, there may be some "shading" by the VideoRay.
This type of set up does not need power from the ROV. It uses batteries, and integration should be seamless.
