The Garmin Forerunner 220 is mostly a running watch but dubs as a pretty nice normal watch too. It’s light (40.7 grams) and it can connect via Bluetooth to your phone.
So Wahoo Fitness released the Tickr series with the Tickr, the Tickr Run, and the Tickr X. All of these chest strap heart rate monitors have dual functionality, in means that they support both ANT+ and Bluetooth.
First off, the Ambit 3 is available in Peak and Sport edition, I’ll use the Sport edition for this comparison as I feel it’s the better option for a triathlete. The Peak is the better watch, but if you swim, bike and run (or any of those by itself), the Sport edition is all you need.
