F1 Fan it is uphill with a slight grade, and it happens if I am running/cycling. It seems kinda strange, since I am training on a campus, University of South Al . There are woods to the left of the road, and just mountain bike trails there. To the right is a couple of medical bldgs, but I circle around to them, and no problem. Who knows?

I've had a Polar A5 for the past five or so months. My first HR monitor. No problems and am pleased that I purchased this model.

Trouble

This little bit of info helped me to solve the problem I was having with unexplainably high readings on my Polar S210, which I really like.
At first I thought it was my wireless Flight Deck because when I came to a stop the high readings on the receiver would stop.
As an experiment I went on a ride with my Flight Deck turned off and I was still getting the high readings, then I simply pulled my cycling shirt up and away from the transmitter and the readings on the receiver went to normal...problem solved.

Thanks F1_Fan, it is greatly appreciated. :thumbup:

Although in this case, the static was the culprit and I think Polars use coded transmitters, with other HRMs, it's quite possible that the FlightDeck's wireless wheel sensor's transmitter could cause a problem. Remember that the transmitter of the wheel sensor is independent of the head unit. Even if you turn the computer off, the wheel sensor will still be sending out signals.

Trouble

I'm not sure about that.
The Polar transmitter does not transmit unless the request is send from the receiver, in other words the receiver has to be turned on.
I think the same applies to the Flight Deck. :confused:
According to Polar, the "coded" in the newer transmitters is only for magnetic pulse cross talk with other HRM. Nothing to do with any other electrical interferences.
When I asked a Shimano Cust. Rep what the transmission frequency or method of transmission the Flight Deck used, he told me to call Japan...must be a Shimano trade secret.

The wireless wheel sensor transmitter is not that smart. There's basically a reed-relay that gets tripped when the magnet passes by. This triggers a pulsed signal from the transmitter.

One thing people should keep in mind when transporting their bike is to make sure the wheel is secured and not turning in the wind and that the secured position doesn't have the magnet too close to the sensor otherwise you end up consuming batteries unnecessarily.

Trouble

If you say so...

Just for kicks, I'll call the happy fellas over at Shimano and pose the question.
Maybe this time they'll give me the phone number in Japan.

Glad I could help... it's one of those silly little things they don't draw attention to in the manual.

I have a Polar S720i which I love. I'd recommend it.

I am seriously considering Sigma PC1600 hrm. Anything I should know (good or bad) about this particular model?

I have been developing some software for polar IR devices, no sonic link support yet.

I really welcome feature requests, bug reports and feedback in general.

I don' thave that particular model but I have the Fit Watch. Its a great HR monitor IMO. And very cool looking.

I just ordered one of these today. Cost me $80 with 2nd day air. I'll let you know what I think once I have it in hand.

Mystery solved.

My Polar FS2 starting showing HR's over 220 today. Only on descents.

Warm, dry weather.

I guess my avg. HR is garbage from today's ride?

Anyone have any ideas on how to keep the static charges from messing up my HRM?

I have a Sigma Onyx Fit model HRM that will do what you want it to do and is very well priced. I bought mine on eBay at a good price and when I replaced the batteries which you can do yourself its been great. It had just been sitting in a shop for a while but its easy enough to replace batteries.

If you are going to spend $200+ on a heart monitor, you might as well get a Garmin 305 that has a lot of advanced cycling features along with HR monitor capability

Bought a cheap Sigma off of E Bay last year which turned out to be crap ... died within 6 months. I have a Polar with a fickled transmitter that is very annoying (one of those soft washable transmitter belts that snaps into the transmitter that is suppose to block interference). I like the HR monitor on my Garmin Edge 305. The Polar has all kinds of functions (upper / lower limits ... targets etc) but the constant beeping is distracting and I usually only look at my current HR anyway.
