Polar stop-watch issue

jrar

Hi all, looking for someone to give me some insight to the following problem, or better still, for someone who has experienced the issue to give mtheir tuppenceworth !

I use a Polar watch / heart monitor, but to be honest, it's used 99% o the time just for timing my training runs. I've don 3 marathons (2 x DCM and last week's Berlin marathon) and worn it each time so that I could track my pace.

In Dublin on both occasions, I started my watch crossing the start line and looking at the watch a few minutes later, it had moved off the stopwatch feature and is displaying a "00" heart reading i.e. monitor readout but showing zero as no monitor attached. Usually, I can re-set it at the next mile marker and away we go.

Last Sun. despite re-setting it several times, I only got one kilometre completed whereby it stayed on timer function for the full km - beyond that, it proved useless so I reverted to trying to get into my usual pace/rhythm and and use the offical course clocks to determine my progress.

I'm assuming that the proliferation of other timing and monitoring devices in a crowded running group is playing havoc with it - and that the density of the running group in Berlin meant I was always in close proximity to someone whose device was playing havoc with mine - anyone else ever experience this frustrating problem ?

ps - I can go on a 20 mile training run and the watch works perfectly from first minute to last so I know it's not a core function problem, or lack of batteries etc.

hot to trot

I have a notion that there is a lock you can set so that it is immune from others nearby. I have used mine for 2 marathons and a few half's and have had no problem, excpet when batteries are weak.
By the way, have you sent off the watch/wrist unit for service yet? I think mine is a bit dodgy and now sure whether to get local jeweller to replace the battery or should I send it to sevice agent. Am afriad I wont have ti back for DCM this year
