Garmin HRM-Dual Heart Rate Monitor

This is to replace the one that came in the bundle, elastic strap wears out, nothing lasts forever

I got almost a year out of the HRM Dual, and it worked well for most of that time. I would wash the strap every 6-10 rides after removing the hrm node, hang dry, etc. Started to see dropouts a month or two ago, so I replaced the battery figuring it may be that. It wasn't. Researching it, there are seemingly a few things that go wrong with these, but my strap didn't have any cracks in the contact patches, the battery cavity doesn't have any corrosion, from what I can tell, all the internal cabling was in tact between contacts and connection point, and even after a battery change and vigilant washing to avoid any salt buildup, it would only last the first 10-15 minutes of a ride, then drop out completely. I'd adjust the fit and it would show up on the head unit again, but at a criminally low HR (like 65HR while climbing over FTP). I even tried shaving the chest hair, to no avail. I noticed that one of the contacts on the nodule itself seemed to have some rust underneath the plastic covering the unit on the backside (around one of the circular metal bases attached to the contacts that snap into the strap). This was something I couldn't find examples of online, so I was a little leary of buying and trying another strap, thinking it might be something to do with this corrosion/rust which would mean my HRM unit was toast and a new strap wouldn't remedy the problem.

I opted to buy a new HRM entirely and just anticipate needing to do so once a year or hopefully get a couple years out of these things moving forward, as they're not cheap.

I had a Garmin heart rate monitor for several years. At first it worked great, then started giving erratic readings (e.g., over 200 bpm when I knew I was around 140-150) or not transmitting to my Garmin computer at all. I spent many hours reading comment about how to fix it, bought new straps, replaced batteries, etc. Thinking Garmin was the leading company for this stuff, I stuck with it for several years of frustration, but I finally concluded that it's just not a very good product, and got a Yahoo HRM and so far it has worked accurately every time. Garmin really needs to make a better HRM.

Simple set up and connection. Have worn it for about twenty rides with no issues. The ability to disconnect the transmitter and wash the strap in the washing machine is an appreciated feature as well.

Me gusto mucho

Happy with this heart rate monitor, have used it for several years and was just worn out! Great product and great price through Western Bike Works!

After about a year of use, it began dropping out during a ride. Garmin replaced the strap and suggested a few changes:

(1) Even though instructions said the strap could go in the washing machine, the spin cycle might fold it and break the wires. Now I just remove the module and soak the strap in the sink while I shower after a session, adding a few drops of dish detergent once a week.

(2) Buh Bump electrolyte cream on the electrode patches before each session.

(3) Leaving the module off the strap until the next session may increase battery life.

Electrode patches may be bubbling slightly after a year on the replacement strap. So far it has worked perfectly, but I got a new strap just in case. I do 5-6 sessions a week, fairly heavy use.

Bought this to use with my Lezyne computer. Comfortable, works great and Bluetooth connection to my computer fantastic. Only issue is that the strap is incredibly long. While it can be adjusted, it is a bit too loose on my female, 58, 115 pd frame even when shortened as much as possible.

I got this to connect both my Garmin Edge and my phone in order to have back up in case one goes awry on a ride, which does happen. It connects to the Garmin with ANT and the phone with bluetooth. It works except, oddly, my Garmin Edge will lose connection and I can't get it back while out on a ride. The phone stays connected. I think it loses connection when I power up the Garmin Connect app on my phone, so go figure. Otherwise works as advertised and is great to have HR on both devices when one craps out our produces wacky GPS.

Great! Put it together and connected with my Garmin 810 right outta the box. Comes with full battery, and has been working reliably since.

Very easy to set-up and use, paired immediately with my Garmin 820 head unit. Properly tensioned with the strap, stays perfectly in place for longer (3+ hrs.) rides. Sensor also snaps off and back on super-easy when washing or cleaning the strap. Haven't had long enough to speak for battery life, but should be a long time.

Well most head units are Garmin and use ANT, and then Ive got a TACX Neo2 (which Garmin recently bought TACX) which uses Bluetooth with my Apple TV. So if you get this heart rate strap your pretty set as it work seamlessly with both the Garmin headunits ANT and Bluetooth as needed. Plus its comfortable and I like the strap.

I've been using my Garmin watch for years to track heart rate but finally decided to try a dedicated monitor. It's way more accurate when compared to the watch and got used to the feeling after a couple rides. I don't even notice it anymore. After you pair it the first time it just works every time.

No longer do I have to record my heart rate data on separately on a wahoo app and then subsequently download it to Strava or struggle to with computability issues when using Zwift. This is simple and easy- no problems so far with Zwift or Strava. The savings in battery costs alone makes this a better choice than my prior Wahoo tckr. So far I am completely satisfied with this product.

As indicated below, I'm a cycling enthusiast. I use it with both my road and hybrid bikes. I've been using Garmin products now for over a decade, and I plan to continue using them as long as I continue riding. I especially like the Connect software that displays additional data regarding every ride on my cell phone. Some of the Connect information is redundant, but most of it is not and it's useful to track training and improvement.

I enjoy seeing my HR and zones while on rides. Learning more about it all with every ride I complete.

I had older monitors, but they weren't reliable, maybe the technology, maybe their age. This monitor has worked flawlessly and make me feel confident in it's numbers.

I had a Wahoo HRM that I used for a few years but was not accurate or consistent. I would constantly have readings that were way off the chart. The Garmin just flat out works. It's dependable and comfortable to wear. I get consistent, accurate readings and never have to question what's going on. Highly recommend.

My last heart rate monitor (same unit) lasted a year possibly two, but not 3.5. And like all HRM's I've ever used this model does not allow you to replace the battery when it's depleted because it never works, which means you need to toss the whole unit every year or two and start again.

I use this heart monitor when on group rides. Typically 50 mile rides. The strap is easy to put on and very comfortable. Pairing it to Edge 810 was easy. I like the easy slip on clasp. It is comfortable to the point that during the rides I forget that I have it on.
