weighting between fresh and salt water

[fisheater]

When I bought a new wetsuit for warm water, the LBS allowed me to use one of their AL80s (as I dive with heavy steel tanks locally) in their pool to get my weighting right. I purged the tank to 500 psi and hovered just off the bottom of their pool with an empty wing.

After everything was dry, I weighed my gear, added the weight of the tank and of me and multiplied by 2.5%. That was additional weight I needed for salt water.

On my trip, my weighting was perfect.

This. Salt water is 2.5% (approx.) denser than fresh. Take 2.5% of your total weight (you and all your gear), and add that to your fresh water lead requirement.
