You are correct that the displacement is fixed, but the buoyancy will not always be the same. Buoyancy is the weight of the water displaced versus the weight of the displacing object. Adding weight inside the cannister will, of course, decrease it's buoyancy. See, I did learn something from PADI! Nothing useful though.
