At every product is thoroughly tested for as long as it takes to get a proper insight into how well it works. Our reviewers are experienced cyclists that we trust to be objective. While we strive to ensure that opinions expressed are backed up by facts, reviews are by their nature an informed opinion, not a definitive verdict. We don't intentionally try to break anything (except locks) but we do try to look for weak points in any design. The overall score is not just an average of the other scores: it reflects both a product's function and value – with value determined by how a product compares with items of similar spec, quality, and price.

Garmin's HRM-Pro Plus heart rate monitor is up to three or four times the price of some on the market, but if you are already enrolled in the Garmin 'family' of devices and you are into multisports then it does bring a lot of extra features over other monitors. It'll work with other devices too, and it is very comfortable to wear, even for long and sweaty workouts.

Check out our guide to the best heart rate monitors for more options at various prices.

Taking the HRM-Pro Plus out of the box, it really doesn't look any different to any other HR strap. You get a pod in the centre, which is now white – it was yellow on the previous HRM-Pro – and an adjustable strap, with a couple of sensor pads on it for monitoring your heart rate. The main difference between this Plus model and its predecessor is that battery replacement is now tool-free.

The strap is adjustable, with a range of 60cm (23.5in) up to 106cm (42in); that isn't massive, but I suppose being aimed at athletes, the majority tend to be quite slender. You can buy an extender if you need one for £8.99, which increases the chest size to 142cm (56in).

The strap is one of the most comfortable I've used. The thin design allows it to contour nicely with your body and it manages to stay in place without exerting a lot of pressure on your skin. I've worn it on some long gravel rides and barely noticed it – not something I can say about all body strap systems.


Things are pretty standard in terms of connectivity, with the HRM-Pro Plus transmitting your data via Bluetooth or ANT+ to whichever device you are using. I connected it without issue to my Garmin Edge 530 and Edge Explore 2, and my Fenix 6 Pro watch.

It also connected quickly with the Bryton Rider S800E computer I've been testing (full review soon), and the Tacx Flow Smart Trainer for use on Zwift.

I had no issues with dropout from either ANT+ or Bluetooth, whether riding inside or out.

So, nothing out of the ordinary there, but if you are using a Garmin device and the Connect app, there are a few bonuses.

It works as an activity tracker, storing details like calories burned, intensity minutes and all-day heart rate, so you can wear/use it even when you haven't got your watch or device in range, like when swimming. Once it makes contact it'll upload all the stored data to your device and onto your daily feed on Connect.

If you run as well as cycle, the HRM-Pro Plus has Garmin's Running Dynamics built in, which'll save you having to purchase something like Garmin's Pod, which costs £59.99 on its own.

Running Dynamics measures things like stride length, cadence, ground contact time, vertical ratio, vertical oscillation and left/right foot balance.

This all works whether you are running outside or indoors on the treadmill.


The HRM-Pro Plus is rated to 5 ATM for swimming so as you can imagine there are no issues when riding in heavy rain. In fact the whole unit seems very well built, and after a lot of high-intensity rides on the indoor trainer over the last few months, salt from sweat has caused no long-term issues.

I have followed Garmin's recommendation of giving the strap a wipe over with a cloth every seven or so uses.

Battery life is reckoned on a year, allowing for one hour per day usage. It uses a CR2032 battery, which you replace by removing the white cover.


OK, £120 is a lot of money for a heart rate monitor strap.

The 4iiii Viiiiva, which Liam tested a few months back, has gone up but is still 'only' £79.99, and that also has the ability to log workout data to pass on to a device at a later time. It can also make ANT+ only devices compatible with Bluetooth, which is a neat touch.

And Wahoo's more basic TICKR strap is just £39.99. Dave reviewed it in 2020 and thought it was excellent.

If you want a Garmin heart rate strap purely for cycling, you are probably better off with the HRM-Dual – a basic device with connectivity to both ANT+ and Bluetooth devices that costs £59.99. But if you do more than just cycling and are really into your data, the HRM-Pro Plus isn't that over the top, price-wise.

I am returning to running at the moment, so I've been using the HRM-Pro Plus for that, and if I'd had it when I was running frequently before I wouldn't have needed to spend that £59.99 on the Running Dynamics Pod, which now just sits in a box on the shelf.

I don't swim, but if I need to know my heart rate in the bath then I am also sorted!


For basic cycling data, the HRM-Pro Plus is more than you need, but if you are a triathlete or just like to play various sports you'll get a lot of use out of it. It fits well and comfortably, and I had no issues with connectivity or performance at all.

Standard strap size isn't that big.

It's pricier than most, even very capable monitors like the 4iiii mentioned in the review, though the Running Dynamics does make up for it somewhat.

How to replace the battery on this heart rate monitor? With the Dual HRM, changing the battery half the times equals breaking the heart rate monitor

I remember when these were 20 quid each.....

The Garmin HRM-Pro Plus is my preferred HR strap for triathlon. Be warned that it falls off when you swim wearing trunks - you need to wear a tri suit. This is stated by Garmin in the instructions, but I can confirm.

I hope its more reliable than the old Garmin 'soft strap' monitors, which were basically consumables, and lasted the life of the battery as once changed, they failed.

The 'hard strap' one I've had since has lasted significantly better.

I'd want to be sure of the longevity before I laid out £120 on this one as the warranty only covers one replacement.

Buy it from a reputable retailer; the length of the statutory warranty is written in law, not by the manufacturer.

I have to say I've had the bog standard Garmin HRM for 10 years or so now, used several times per week, and it's still working perfectly
