ANT+ is the standard wireless transmission protocol for fitness equipment these days, for collection and transfer of sensor data, be that from a heart rate monitor, PowerTap or cadence sensor.
If you’re planning a set-up for your bike that’ll give you all the info you need for the perfect training session, or perhaps you’re hoping for a box with a nice shiny Garmin in your stocking this year, there’s now a site with a full directory of ANT+ compatible devices.
The directory is perfectly easy to use: just enter the first piece of equipment you’re planning to use, and read a short description of it. From there you can see all the compatible products, and cross check to make sure other monitoring equipment will be suitable too.
For more information, see This Is ANT.
