Hi Carena,

Is 560 Cal the same number as you get if you input "walk"? It may be a standard activity number. (I'm too lazy to check it myself, sorry.)

Now for a real geek comment: Since during scuba you know the max amount of Oxygen you are consuming (cannot consume more than what you carry in your tank), you can probably get a good estimate of energy displacement that way.

Is HR really proportional to energy displacement? I keep reading that sex is not a good weight loss exercise yet my HR goes really high just thinking about it. I can also start counting meetings with my boss as exercise. ;)

Hi thanks for the feedback. I've heard there are HRMs that are waterproof up to 30 meters. Actually I'm just curious how many calories I burn when scuba diving. The fitness tracker on Spark People, shows I burn 560 calories per 80 minutes (about 2 dives), and that's A LOT!. I mean, doesnt it matter wethear you're going against the current or at a relaxed pace.? The tracker just has "Scuba diving" for the activity that's all.

I want to get a HRM anyway so I know how many calories I really burn during any exercise, so I was thinking if I'm going to get one I should get one suitable for water activities.

Hi Carena,

Welcome to the team!

I have a Polar® HRM that is "waterproof", which I have used for swimming.

Even though I have not tried it, I speculate that it's NOT scuba-proof. Kind of like Casio watches: they are Ok in a pool, but take them scuba diving, and most will not come back dry inside.

Are you trying to get biofeedback in order to lower your HR to get some Zen diving and use less air? Or are you actually trying to get a good workout underwater with a limited amount of air? :)

I agree. It's a great way to gauge how much of a workout we are getting from diving. Let us know how it goes!

Thanks! I'm happy to be here. Yes there is such thing as waterproof heart rate monitors. I'm thinking to get one. Since I'm a Divemaster I think it would help me a lot.

Hi everyone.

I joined several days ago, just havent had the chance to post yet.

I'm Julia. I'm a Divemaster living and working in the South East Asia, currently in Malaysia.

I was wondering if anyone here tried using waterproof heart rate monitors when scuba diving. And if so, how was it?

Any suggestions on which heart rate monitor is best for diving activities?
