## Buoyancy Calc Description
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.

## Buoyancy Calc Reviews in United States

### ***-- "A little off"
The app recommends 28 pounds based off of my standard setup but I dive with 24.  Still though I would say this seems to give a decent estimate.
-- AMCrumpy, 2025-03-23

### ****- "Could be better but good"
Of course I see everything that says it over weighs, this is just a suggestion that I would like. The ability to not include the tank in the calculations for free diving because 7mm suits can be quite buoyant and may they need some weighing down, it may also be helpful for snorkeling
-- no money take the L lolol, 2023-11-07

### **--- "Possibly Good"
This app is super simple to use, very intuitive. 
It does however not match what I use (or others I checked with), weight wise. 
Also, it appears to not correctly convert between pounds and kg.
-- EB Review, 2023-02-11

### *---- "Doesn’t work anymore"
Used this for multi-mode buoyancy calculations as a ball-park estimation, mostly for vacation when diving in different configurations.  Worked well for that application, but App doesn’t work anymore.  Deleting.
-- Buongi, 2023-01-21

### *---- "Totally inaccurate"
I’m a DM with 40 years experience i dive with 22 lbs the app Calc my required weight at 34lbs.
-- DJ 3898, 2022-08-22

### ***-- "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.
-- Humusbchittenme, 2022-07-24

### **--- "Not safe"
The weight recommended to me was almost 4 times the amount that is considered safe for me. Someone relying on this could literally be killed due to being overweighted and drown. 

2 stars because the interface was easy to navigate.
-- ripogenus, 2022-04-10

### **--- "Error for steel tanks?"
When switching from steel 100 to steel 80, the calculator says add 1 lbs. This must be wrong?
-- speechless12345, 2022-03-28

### ***-- "Alright, but only for single tank diving"
Limited cylinder sizes and no option to add more than one
-- Dawgnig, 2022-01-31

### *---- "This calculator is off"
This is off by a lot!! It doesn’t factor height or muscle mass so just based on weight it gives you a much higher allotment of weight to wear while diving!
