To avoid unnecessary wear on the drone and tether, after each dive in salt water, the drone and tether must be rinsed with fresh water.
The drone can either be submerged in freshwater (indoors & outdoors) or rinsed with a garden hose. Running the thrusters submerged in freshwater after each dive will keep them in shape longer.
The tether should also be rinsed when used in saltwater. Unroll the tether from the reel to keep the Blueye Surface Unit away from the water
If necessary the surface unit can be cleaned with a dry cloth.
