Reddit reviews SPECTRA 360 12-08 Electrode Gel (Pack of 2)

It's the strap. The monitor is picking up your cadence until you get nice and sweaty. If this bugs you (it bugs me, for sure), you can buy some of this:

It's dirt cheap and it fixes the problem. You'll see your heart rate start low and then slowly and steadily climb to 140 with no jumps like you're seeing now.

I have an eczema patch nothing worked for, until one night it hurt like hell, the only thing near me was the electrode gel for my tens unit. So I tried it just to stop the movement stretching pain so I could sleep. Totally worked. I just use that now. Maybe worth a try, stuffs cheap. $10 for two big tubes

had this problem - there are potentially two solutions - use some conductive gel (like they use for ultrasounds) on the sensor buttons that insert into the chest strap.

Alternatively, as i had to do recently, buy a new chest strap - the little holes become looser over time so the connection is poor, even with the gel.

Your friendly SA's might have some gel, otherwise available from Amazon - literally enough for 100 ultrasounds or a lifetime at OTF.

I buy them on Amazon. I've tried Spectra electrode gel and Wavelength MP ultrasound gel. They are great and cheap.

I just lick it. Or you can use electrode gel

One thing I've found that greatly helps is using EKG gel on the strap every ride. This will last you for years: http://www.amazon.com/Spectra-360-Electrode-Gel-Laboratories/dp/B0093J2GM4/ref=sr_1_2?ie=UTF8&qid=1374794485&sr=8-2&keywords=electro+gel

Some kind of app that filters out HRM readings over a threshold would be really helpful though.

a little bit of this on the back and you’ll never have an issue

I use electrode gel. Once I started using that, I've rarely had any problems with erratic HR readings. It's cheap and the tubes last a long time.
