Run Run Away

Question:

Hi, I’ve bought Polar S810 recently and I’d like to ask some questions: 1. Has anyone tried (with this one or some other Polar) to record lap times during swimming? There is a warning not to use buttons under water, but that would mean that I should have another stopwatch for recording lap times. Is its’ waterproofness really so bad? 2. Yesterday, I tried to use it in the sea, and there was no pulse at all. As soon as I put the transmiter under the water, the pulse becomes zero. 3. During the running training (with RR intervals set), there was around 3% errors (which means 3-5 beats per minute were not received correctly, and that is really too much). If anyone has any experience with all this, or has any advice, thanks a lot. – Pedja.

I’ve see this statement on just about every watch I’ve used.  I think it’s a pretty standard warning.  I should have listened to the advice, because I fried my timex ironman using it underwater. 2.

I’m no expert here but I’ll give it a shot.  The transmitter works off of electrical signals from your heart.  Salt water has about the same electrical conductivity as you body, so I think that you have effective grounded yourself when you wear it in the ocean.  Does it work in a pool? – Hide quoted text — Show quoted text – 3.

810?  thought it only went as high as 710. I have experienced it going up to 200 and reading zero,etc. to my friends they say its just cause the way my chest is built. it doesnt have good conduction. theres a gel out there called buubump, might work. Dont worry about the water i use it all the time, sea & pool, I just hit the buttons with my wrist out of water to be safe.

Response:

Yeah,  I’d be careful about pushing buttons under water. My buddies and I swam with ours in a pool and a lake all summer with no problems.  However, we were not pushing buttons while it was wet.
