Where can I get a waterproof scale?

[CokeCanNinja]

I want to do hydrostatic weighing to see what my body fat is, and you need to weigh yourself under water.

Bit more to it that just needing a waterproof scale...

They are just weighing her under water. You can do that without needing a big complex chair and all. Here's how you do it (from the book "The Geek's Guide to World Domination"):

1. Weigh yourself, write it down.

2. Place a scale on the bottom of a hot tub or pool.

3. Stand or sit on the scale. If needed, use a weight belt to make yourself sink, and then subtract the weight from your total.

4. Submerge yourself completely. Blow the air out of your lungs. Holding air will make you seem fatter, so blow it all out.

5. Read your underwater weight. Write it down.

6. Plug your numbers into the following equation:

DryWeight / (DryWeight / WetWeight) = BodyDensity

7. Convert body density to percentage of body fat using the following equation:

%Bodyfat = (495 / BodyDensity) - 450.

It's pretty simple, and I don't like those caliper things.

Isn't that the definition of Hydrostatic weighing?

If you want to do it yourself, then you are making it too complicated. Who cares if the scale is waterproof - put it in an sealable plastic bag...think oversized freezer bag with a zip close, and go for it.

I could do that, I'll need a big bag through.

You can get clear trash can liners

That's true.
