Heart Rate Data On Virtually All Your Training Toys
I’ve been using a Wahoo trainer and Zwift via Bluetooth for a couple years now but have been frustrated that my Garmin ANT+ HR monitor that came with my Edge 1000 wouldn’t pick up on the Zwift app. If you use Zwift, you know that it’s ANT+ or Bluetooth. You can’t run both at the same time or they fight for control of your trainer.
In late January Garmin introduced their HRM-Dual heart rate monitor which has dual transmission. This makes it easy to have accurate heart rate data on Garmin devices, compatible gym equipment, and third-party training apps. Yep, I did a little happy dance as I read the press release.
Here’s a list of devices and apps I paired and tested with the HRM-Dual.
- Garmin Edge 1000
- Garmin Forerunner 920 XT triathlon watch
- Wahoo Kickr trainer
- Wahoo Headwind
- Wahoo Fitness app
- Zwift app
- Apple iPhone X
I found it simple to pair the HRM-Dual to both my Garmin devices, Wahoo Headwind fan, Apple iPhone X and 3rd party apps. Just pair as you would any other sensor and be sure you are within 3 meters of the device. The HR monitor picked up quickly and then consistently read the same HR no matter what device/app I was using.
Same Comfortable Garmin Strap
If you have used the Garmin soft strap you know it is comfortable, adjustable and washable. You just put it on and forget about it. Garmin recommends you wet the contact areas before putting it on, but it was rare I needed to do this step.
The HRM module snaps on/off the strap in order to safely wash it by hand or on the gentle cycle in cold water. Garmin suggests rinsing the strap off after every ride and machine wash after every 7 uses. In both cases, hang to dry. I use a linen bag when machine washing, so the closure doesn’t snag any clothing.
The HRM-Dual is rated IPX7, 1 ATM water resistant. That means it is suitable for splashes, rain, snow or showering. But it is not suitable for swimming, diving into water, snorkeling, scuba or high-speed watersports. Basically, don’t throw the HRM module in the washing machine. You’ll be sorry!!!
About a month ago, I had to replace my older Garmin strap because it was falling apart. The glue holding the electrode covering wasn’t holding any more. I cheeped out and went on Amazon to buy a third-party version for $13. Well, it wasn’t comfortable at all. The strap was made from rough material the edges weren’t smooth. Also, the closure didn’t have that piece of material covering the hook, so it chafed. Basically, the cheap knockoff strap is just worthless. Live and learn.
According to Garmin’s web site, the CR2032 battery (3 volts) will last up to 3.5 years based on average use of 1 hour/day. When the battery does run out, you can replace it yourself by unscrewing 4 screws on the back plate
Garmin’s new HRM-Dual heart rate monitor has dual transmission making it easy to have accurate heart rate data on Garmin devices, compatible gym equipment, and third-party training apps. Using ANT+ or Bluetooth, you have more possibilities to connect. This is a great step forward in compatibility with all your “training toys”.
