Garmin has released a new update that should make heart rate tracking on your Forerunner watch more accurate – and you can install it today. The new software, beta version 19.13, is available for the Garmin Forerunner 965, , , , and the newly released .
To get it, you'll need to join Garmin's public beta testing program, which will give you the opportunity to try new features and fixes early in exchange for your feedback and help with spotting any bugs. The new update makes a few changes, but the most interesting (as reported by Polly Allcock of ) is a tweak that allows you to prevent your switching dynamically between collecting heart rate data from its own optical heart rate sensor, and a connected chest strap . The ability to switch between these sources automatically was introduced with a beta software update in April.
"The biggest benefit of the feature is for running activities," . "A heart rate strap is usually the most accurate source of heart rate data for running but occasionally there can be inaccurate heart rate at the beginning of runs, often referred to as start-up noise. This is caused by poor connection between the skin and the electrodes and typically resolves once you start to sweat.
" If your watch detects an unsteady signal from your chest strap heart rate monitor, it will automatically switch to using its own heart rate sensor instead until things stabilize. It makes a lot of sense, but some users prefer to use their chest strap exclusively, so Garmin is.
