Ballast Weights

Standard dive weights may be used to provide any necessary ballast. The weights may be
secured to the black skids located on the bottom of the housing, using standard cable ties.

It is recommended that the unit be set up to be very slightly negative to allow for easy
underwater maneuvering.
