How Much Weight Do I Need?
Sounds familiar right? You just arrived at a beautiful dive site to explore, you’re gearing up and then the dive guide asks how much weight do you need? Hmm, what was it again, did I make a note in my logbook? Did I use a wet suit, dry suit, short or full-suit, salt water or freshwater (like the cenotes). It’s very common problem among us divers.
One the one hand, nobody wants to bring too much weight. You don’t want to sink like a rock nor have to compensate by overinflating your BCD. Resulting in more drag, more water resistance, since the surface breaking the water column is now increased and carrying unnecessary weight on the surface and in the water. Which means you use more energy and automatically will cost you more air.
On the other hand too light is also not an option. Carrying too little weight can jeopordize your safety stop (and deco stops). Especially in cenotes this is another argument why you should always have a balanced configuration, because in overhead diving you would risk ending up to the ceiling, keep on fin kicking down to hold your position, as your tank is becoming more empty.
The challenge lies in finding a balanced configuration. There are 3 ways of determining your weight: theoretical, beginner and technical way.
