I have tried both Spectra 360 gel (about for 8.5 oz) and Buh-Bump cream (about .50 for 2.5 oz) to improve the functioning of my heart rate monitor (HRM) chest strap. I prefer Spectra 360. Both products provided a good stable connection and heart rate readings. Spectra is a substantial clear gel that adheres well when you apply it to the chest strap. Buh-Bump is a thin liquid cream that tends to run and drip off the chest strap. Spectra cost me about /oz while Buh-Bump cost about /oz.

I need a reliable HRM reading because I use a treadmill program which sets the treadmill speed based on my heart rate. If my chest strap does not make a good connection, the heart rate reading jumps around, and the treadmill goes a little berserk trying to get my heart rate reading to the target rate.

Both products provided a good HRM chest strap connection, but Spectra 360 was cheaper and easier and more pleaseant to use.

I had been having problems with my heart rate monitor readings dropping out during mid-exercise so I decided to try electrode cream to see if it would help. Using Buh bump solved the problem. I haven’t had the problem with drops outs or crazy spikes in my heart rate monitor since I started using the cream. I only need to use a little bit of it on each electrode so the 2.5 oz size should last for quite awhile. The stuff has a nice clean scent as well.

I can not write English well, so I write the conclusion only.

I have tried a lot of gels and creams for my Polar chest strap, which I use with my Tunturi treadmill in HRC programs.

Till now, I had used several gels and creams, but they were not successfull for the job. The treadmill showed much more beats and so, the machine slowed down and the program did not work.

Now things chavged. I see 500+ calories burnt and 7Km distance, while with the other products, I saw 350calories and 5.5Km, at the same time interval.(1 hour).

Now, I add this for better results.

I use two pieces of cotton cloth cut to fit the electrode side of the strap, which ,(the cloth),I immerse in water first, and put them on the electrode side of the strap, putting some cream on both sides of the cloth.

This makes the surface moisture more time, so the system works very well.

With the addition of the cloth, I would put a 5 to rate the item.
