Worked well until it didn't

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.

Reliable data so far
by Paul
Competitive Racer

I bought this to replace another Garmin HR strap that died after 2-3 years of use. I've been using the new one 3-4 days week for two months and have had no trouble with dropped signals or wonky data during rides and runs. The strap pairs easily with my Wahoo head unit (ANT+) and my iPhone (bluetooth). I've even worn the strap overnight to measure sleeping HR data and only noticed two points where the signal dropped briefly in a 7-hour period. Before working out, follow the instructions and wet the strap before putting it on you. You should also follow the instructions about regular washing, especially if you're a heavy and/or salty sweater.

I can't comment on battery longevity and replacement. However, my package did come with Garmin's proprietary screwdriver, which appears critical to opening and closing the battery compartment.

Promise but typical Garmin HRM failure
by Timberwolve17
Cycling Enthusiast

9 of 9 customers found this review helpful.

The major reason you would consider this is because of the Bluetooth + ANT support so you can zwift and use your Garmin computer at the same time. Sounds like a great plan, and when it works it is awesome.

My Garmin softstrap/removable hrm units have all had significant issues with hanging heart rates. You can start your ride, HR 75 bpm, 10 minutes of max effort later its still 75... remove the hrm, wait a minute reconnect suddenly its 185 bpm, stop all effort, take a seat on a bench, wait 30 minutes and your HR is still 185...

Thanks to an article from DC Rainmaker I learned that this is a feature from Garmin, want to impress your friends with obviously wrong HRs? Depending on how you play the Garmin strap game you can. This is not a sweat issue, i run my straps under lukewarm water prior to each ride in addition to spraying my chest with water. I wash my straps with technical fabric soaps, after no more than 2 uses, and rinse after every single use.

DC Rainmaker to the rescue, apparently it is a strap issue because he discusses using a polar strap with the garmin hrm. The connection buttons are technically a few mm spaced differently but it works. Tada! My garmin HRM Dual is back to working. Notably this issue has not occured with my Garmin HRMs that are built into the bands. I would not buy this again, I would love to sell it for half of what I paid and just upgrade to the HRM Pro with BT, ANT, and the old school strap/hrm one piece but that�s another discussion for another day.

Do Not Waste your Time unless you have an old Polar strap to use with this HRM.

Happy but with two caveats

Easiest to use (comfort, consistency) of any brand I've used over the years. Both my wife and I have moved to Garmin Bike Computers so we just adopted the Garmin Duals that came with the computers.

Two things... 1) battery replacement didn't go well with one of the Garmin transmitter units... I got the battery out, the new one in, and it worked but I damaged one of the screws so I was not going to be able to replace the battery again in the future. The new, new HRM being reviewed now comes with a 'special' screwdriver to use in battery replacement so things may be less risky the next time.

2) I've had two units start to corrode around one of the terminals that snaps into the strap. The two terminals look like a different color/material but one certainly starts to 'rust' before the other. That has happened on two of these HRMS for me. I've tried Garmin's recommended cleaning/drying strategy and I can't say that is extending the life vs just not worrying and just replacing every year or two once it dies. The good(?) news is that I may never need to replace a battery again because the thing rusts before the battery needs replacing.

Final note, the description says 'may not need to replace battery for up to 3.5 years'... welllll... I rode 11,000 miles last year with the HRM and the battery needed replacement early this year... so 3.5 years not so much, unless there are internal changes now that make battery life longer.

A patchy start, but works fine now.
by Anonymous

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.

Comfortable and works well
by Anonymous
Cycling Enthusiast

This HRM is much more comfortable than an earlier Garmin HRM strap. In dry weather such as cold winter days, it's important to first spray or drizzle some water on the electrodes to get readings started. Otherwise, you may need to wait a bit for sweat to do the job early in a workout. The HRM has worked very reliably and has provided consistent readings on my Garmin bicycle computer. A tool was included for removing small screws when the battery needs replacement.

Better than Wahoo
by Rick

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.

Wish I�d waited
by Mark MN

So it works but I bought it so that I could get heart rate on my watch and Zwift at the same time on my trainer. Haven't gotten it to work that way. I ended up getting the pro version and it has worked flawlessly. This one works for either but not both at the same time from my experience. Tried it connected to my watch with both ant+ and Bluetooth and didn't play well. All that said, it would do either perfectly well, so four stars it is. I should also mention I would have tried harder to figure it out if the pro hadn't gone on sale. May we'll be a way to make it work that I didn't search hard enough for.

Works great, but a few tips may help
by Anonymous

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.

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.

Good but Could be Better
by JP
Daily Commuter

I've had two of these. They work well with my Garmin Edge and are reasonably responsive to changes in heart rate. The strap needs to be run under water before you put it on, and I rinse/soak the strap (with the monitor unclipped) after every ride (3-5 rides/week).

Why have I had two? They seem to need to be replaced every couple of years. After several months you'll see accuracy drop/disappear, which is usually fixed by replacing the battery. But after a couple of battery changes, the monitor craps out totally and battery replacement doesn't fix it. As an annual cost it's not a big deal, but it's odd that this item has such a short lifespan. By comparison, my speed and cadence sensors have never needed to be replaced.

And the comments about battery replacement are spot on. '70's-era tiny-screw technology. Use the right screwdriver, put on your patience face, and soldier through. Seems like Garmin could come up with a more human-friendly design.

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.
