As noted earlier, there are a bunch of changes to the M430 compared to the M400, so it’s worthwhile diving into those first to ensure everyone is on the same page.In one consolidated list, here we go: Added optical HR sensor: Polar believes this 6-LED sensor is their most accurate to date Added vibration capability (alerts): This does however replace audio alerts, which go away Slightly increased battery: Mostly to maintain battery life with added optical HR sensor Added new low-power GPS modes: These enable the unit to get up to 30 hours of GPS-on battery time – High Accuracy Mode: 1-Second Recording Mode: Plots a GPS point every second, HR is every second too – Medium Accuracy Recording Mode: Plots a GPS point every 30 seconds, HR is every second still – Low Power Recording Mode: Plots a GPS point every 60 seconds, HR is every second still Changed the wrist strap design: This was to improve optical HR accuracy by reducing weight and increasing tightness.Before we head there though, let’s chat about how activity tracking works on the app Sure, I already showed the daily step totals within the watch, but let’s look at how they show up on the app. It shows you an overview of your day, complete with activity levels throughout the day.
Inactivity stamps (which my brain automatically translates to tramp stamps…every…single…time), is when you’re lazy and the unit has to give you a verbal warning.Our Word of the Year choice serves as a symbol of each year’s most meaningful events and lookup trends.It is an opportunity for us to reflect on the language and ideas that represented each year.While the M430 is a modest upgrade to the M400, it does bring with it features that enable it to keep up in the marketplace – notably an optical HR sensor.But the list didn’t stop there, they’ve also added in vibration capability as well as new lower power GPS modes to get longer battery life, plus a slew of smaller changes that I’ll dive into more deeply.
