Heart Rate Monitor

[robertdormer]

Hi all

I was wondering if anyone has experimented with a heart rate monitor while diving?
Im interested in recording my heart rate during a dive. I do not want to buy the expensive dive computer currently on the market to do this, and was wondering if anyone had tried taking a standard pulsar or similar on a dive with them?

Im guessing that by having the watch in your pocket during the dive should be sufficient enough to pickup the chest strap.

Thoughts welcome

Cheers

Robert

Not sure it's a good idea as the watch will get pressurised. If the case isn't strong enough it may fracture. It may be perfectly Ok, but it's something to consider.

I did.

One issue though, be careful the pressure doesnt break the LCD in the actual watch receiver - mine was ok on a 12m dive but ive had a mobile phone screen break before now on a 35m dive when i forgot to take it out of pocket pre dive.

As for pulse, only done it once, was a fairly relaxed dive and was around the 80 mark for me. Highest rate was kitting up which i absolutely hate and get knackered doing.

Will try it again next time.

Not sure what the affect of being frozen will have on it but as winter is here i suspect i'll find out.

The back of my Polar says water resistant to 30m... so it might be OK... I might take it on a shallow dive in a couple of weeks time (under the drysuit) just to see!

I'm guessing that my heart rate max will be doing the highland fling trying to get my fins on in my "slightly too snug" drysuit... interested to know what my HR will be doing underwater though - I will set the zone for 80-90Bpm and see how long I spend "in zone" on the dive - a bit of experimentation and I should be able to pin down a normal HR underwater.

Cheers guys.

Saliorboy let me know how it went, and more importantly does the watch still work after the dive!!

Off to scan ebay now then....

A word of caution if I may .............. I took a 100m rated accurist on a 50m dive. 100m rating is for "Snokel use". No problem on the dive the watch stayed watertight, but ................... the face came out of that watch about 2 hours later, with trememdous force, sounded like a gun shot, If i'd been looking at it As it was it made a nice dent in my mates car.

These water resistance claims are all rubbish, they are all static ratings, as soon as you move it all goes out of the window. How about putting the watch in a waterproof box, take the guts out of a torch or something like. It'll be interesting to find out what happens, doesn't the pulse rate drop under water - mammalian reflex or something.

I might just start walking back on my little experiment.... I like the torch idea - maybe leave it inside to equalise after surfacing... does seem to be a complete faff just to find out my HR!
