Quickly find out the suggested weight you should add when scuba diving in different environments. Based on PADI's Peak Performance Buoyancy basic weighting guideline*. Enter your weight in pounds or kilograms, and additionally set the type of water, tank, and exposure suit to dial in a suggested amount of weight to help keep you neutrally buoyant.

*Note that this app and the developer are not officially a representative of PADI. This app will give the user a good estimate of the weight needed for the environment selected, but there are always adjustments needed to achieve peak performance, based on gender, physique, exposure suit age, accessories, etc.

Ballpark Calculator

Not bad as it will get you somewhere near your required weight. I’ve used this as a weight estimator for my students and it always overweights them sometimes by a significant amount. Once you get used to it you’ll start to come up with a fudge factor that works for you. Once you know what your fudge factor is properly weighting yourself when changing tanks, exposure suits and environment becomes a snap.

The best buoyancy calculator!

This is hands down the best buoyancy calculator app on the market. I should know, I’ve used them all.
I consider myself a seasoned diver, having dove with all the greats. Pete Lecrerc, Sunny Drinkwater, you name em. But for some reason I can never seem to sink as well as them. This app has changed everything. I am basically a well calculated rock, it’s the best.

Jokes aside, this is a solid app, you should download it.

Great App

Great app for on the fly calculations. Developer please check the salt water / dive skin suit calculations as no matter how much weight you put in, it always gives you the same calculate result of 2 pounds.
