desired to be exported.

Question 23

What is the best method for post diving the fusion ROV after a mission?

Answer 23

The best option is to fully submerge FUSION in fresh water and run thrusters at a low gain level to move the water and clear out areas where debris can get trapped.

Question 24

After a mission what is highly recommended to help remove salt, mud, silt or other buildup?

Answer 24

A fresh water rinse/soak

Question 25

If it is not practical to fully submerge the Fusion ROV what is another method to post dive the Fusion ROV?
