GarminHRM-Dual Heart Rate Monitor (Return to Product Page)

This sensor has a real poor battery replacement design using four very very tiny screws to hold the back cover in place unlike all their other sensors that have easy to turn and pop off backs. I get about one year out of the battery and the screws are either impossible to get out (do not drop them) or they strip out when replaced. I have to glue the back on with silicone glue as all the screws or their mounts have been damaged over time.

Other than the pathetic battery design it seems to work well and the strap is washable. If the battery design would have been sensibly designed I would given it five stars.

I have three Garmin HRMs that do not work. Most recently, I bought the HRM-Dual last year, and it has quit working. Now I am dealing with Garmin on a warranty issue, which I would rather not have to do. I have switched to a Wahoo monitor and am quite satisfied at this point.

I've only had the Garmin HRM for three months and it simply works everytime with my Edge 520 when I'm on the road or with Trainer Road when I'm riding indoors.

My old Garmin HRM wore out. I bought the new Garmin Dual Heart Rate Monitor to replace it. I couldnt be happier. One plus this new HRM works with Zwift and your heart rate shows on the screen and also in Zwift Companion app. The old Ant monitor was not recognized by Zwift.

The strap on my old Garmin HRM wore out. Ordered this as a replacement.

Nice that Zwift now recognized my HRM and both Zwift and Zwift Companion now display heart rate information. It wouldnt recognize the Anti information.

I have done several rides and this product works perfectly.

This is a reliable HR monitor with long battery life.

I use this when walking, cycling etc. Pairs nicely via ANT to my android using my Workouts app. The HRM signal is very reliable.

I use this heart monitor strap 3-4 times per week for 2 hour rides each time. This is a very comfortable strap and once adjusted for my chest stays in place. In fact, I never notice that I have this strap on.

I use this heart rate monitor (HRM) in combination with my Garmin bike computer and trainer (Zwift interface). It is comfortable on long rides. Definitely make sure to follow direction and wet the band prior to riding. This HRM was bought to replace my more expensive Garmin HRM PRO, which had a very short life span under my usage conditions (seal failed, electronics were subsequently corroded and quit working).

Gets the job done and lasts a long time for my use!

So in 4 years I'm now buying my 3rd strap. The first one lasted 3 years!, The 2nd one only lasted 13 months, and completely failed, New battery didn't work and the plastic screw holes deteriorated, to where the screws would no longer hold the cover. I might add that is how the 1st strap failed, the screw hole plastic deteriorated and would no longer hold the screws.

The Garmin HRM-Dual Heart Rate Monitor works well. Read the instruction for usage and care. Must be wet for it to work. Connects fast to my Edge 830 and Zwift.

I bought this to use with TrainerRoad. I only have a dumb trainer, so triangulating between my heart rate, my cadence, and my "speed" is an important element of getting an accurate FTP and workout. It connected to my iPad without me even having to set it up or search for it. Glad to have it aboard!

Very accurate

After many years of salt and sweat my first transmitter finally failed. Don't know if it was merely the snap-on unit or the strap itself, but I grabbed a new one anyway when BTD had a recent sale. The newest one seems to stay in place even better than the last one, which is key. The very first units from years back were stiff and slippery and often slid down if not cinched uncomfortably tight.

This is my wife�s first chest strap HR monitor. It fits her well and gives her accurate legible HR data on her Garmin. She tried using her Apple Watch but it was too hard to read while riding, less accurate and couldn�t be displayed on her Garmin.

Ordered this for my partner. It paired quickly with his Edge 520, but then would read HR pretty inconsistently the first few rides even after putting a little water on the strap. After 5+ rides, it works fine now. Kind of bizarre considering that I never had an issue with my older Garmin HR monitor.

We have been a Garmin family for years. I use my Dual HRM with a Garmin Edge for cycling. I purchased the Dual HRM for spin classes and noticed that every so often my heart rate was dropping out. A check of the HRM revealed that all four (4) screws had cracks around the plastic and was being held in place by the snaps and the strap.

The initial monitor has seen its best day. It was getting a little ragged and I could not adjust it to maintain good contact. So a new one was in order. Good price, quick shipping and it arrived very quickly. A good product

and a good company to do business with.

I've had three of these now (one was the older version). The last two duals that I have stopped working after a few days and was returned for one that worked for about a year. Both of them stopped working in the same way, that is the heart rate sent was stuck at 73 bpm. No adjustments of the straps helped. I was glad Garmin replaced the first one for free, but now I doubt they will replace the second one since I've had it for about a year.
