Great improvement over prior versions

I used the first generation strap successfully for 2 months, after which it would not accurately measure my heartate. I tried ba-bump, constantly wetting during a workout, still no luck. So I used a polar strap (with the Garmin attachment), and that worked great. Upon losing that strap, I had to order this one. So far, after about 20 uses, it's working well.
It has a 3rd, new area that they recommend wetting. If you're like me, and using your wet fingers, it's hard to do, as this area is more clothe like, as opposed to rubber like the the 2 other nodes.
It's supposedly machine washable, but I still hand wash it.
Overall, satisfied with this newer strap. I've used it running, and on bike rides. I have yet to wear it in the water and onto a bike ride (triathlon application. As you know, the monitor is not for heart rate use in water, but can be worn in the water for us triathletes.

Works great! I forget it's on!

I am riding about 4 times a week and training in specific heart rate zones to prepare for a century I have coming up and got this strap to use with the Garmin heart monitor I had previously. It is nice because a) you can snap the actual heart monitor part off the strap which saves the battery and allows you to machine wash the strap on delicate, and b) thee fabric is softer and more conforming than the regular one that I believe is the base model and is hard plastic. It just makes it more comfortable. The adjustment on it is a little fiddly but nothing terrible. I slide it up under my sports bra band and don't even notice it. I also find that it is more sensitive than the base model that I had before. I haven't had to wet myself down to get it to work yet. I'll get another strap like this if I wear it out.

good update

I have had a chest strap Hr monitor for a long time and it has been accurate and with the same battery has lasted for years till I dropped it in the parking lot and a car ran over it. The new silver strap version seems to pick up the HR a little more accurately, but I am getting a rash at the site where the antistatic pad is. This may be something that just applies to me. Overall, a great device that is long lasting.

Garmin HRM 3

The Garmin HRM is so far a great addition to my training tools that I use to gage, evaluate and maintain my fitness for Multi Sport Training. The only down side is the price of over $70.00.

Garmin HRM 3 Premium

Seems to better solve the HR spikes I periodically dealt with in the previous version.

Negative Reviews:


I have bought this heart rate monitor with a Garmin Edge 510 cycling computer and a cadence/speed sensor. I am very happy with the 510 and the c/s sensor.
The HRM is another story. It worked somewhat okay during the first 10 days. I had to ensure the electrodes and third area on the strap were wet, that the strap was positioned and tensioned just right. Now, after two weeks, it has become completely unreliable. It will either not work at all or give very bad readings.
Considering how expensive this sensor is, it's is an outrage that Garmin would release such a faulty product to the market.

Works sometimes

This is the fourth hr strap that I have gotten for my garmin 510. They have all had fairly spotty performance. REI is great in replacing them, but I wished that they just worked. It has been frustrating.
