New! Supports Subsonus from Advanced Navigation. This is a system to trace underwater transponders. They are put on drones, anchors, divers, fishing gear etc. There is also a small sonar under the boat. Olex will then show the transponders in 2D and 3D! Update rate are up to 1.3 seconds.

Subsonus lets you see exactly where your fishing gear is. Keep tab on divers. Place anchors correctly in relation to bottom snags. See where your trawl doors are, including their spread.
