Every body of water has a unique density. To adjust, the Sierra X-Scooter comes with a weight pouch in the nose and tail. Using lead shot (recommended), you can dial in your scooter so it sits just slightly positive in the water. You should have 4 pouches of two different colors. The colors are used to differentiate pouches for either the nose or tail. If you frequently dive fresh and salt water you should trim your scooter with 2 of the bags for fresh water, and then with the fresh water pouches in place, add the second set of pouches containing the difference needed for salt water. This way you can dive either, with minimal effort to adjust. To mark the pouches, you can simply write on them with a felt pen.
This weight table is meant to be a starting point for configuring your Sierra. Make sure you test, adjust, and re-test before diving into a new body of water.
