Buoyancy Calculation Before Getting Wet

[addohm]

Hi, are there any calculators out there that at least get you close to what you need for bouyancy in salt and fresh water? Or do I still have to do it the old fashioned way and manually weigh all the parts with a fish scale and bucket of water?

Ah, sorry. I gotta remember the "Tips & Techniques" is under the Camera forum.

However, I do know you can get the increase for salt water as 2.4% of the total dry weight. I use a luggage scale and a hot tub for measuring freshwater buoyancies.

This is an excellent, detailed spreadsheet that lets you easily estimate a starting weight based on various configurations of exposure suit and tank type. Developed by a sharp Scubaboard member.

I've found that you can spend a lot of time trying to calculate housing buoyancy with math or in buckets or bathtubs, but the best way is always to jump in the water. Find a pool at your local dive shop or elsewhere you can use to test a new configuration. It's also the only way you can really test and adjust the trim of your rig, which is also very important mainly for dome ports (especially acrylic ones). I use adhesive wheel balancing weights to help with that.
