Hi, we have this watch and it has been great... yes, you need the ANT unit to connect wirelessly to your computer, and it comes with the watch. It's just a little thing that plugs into a USB slot in your computer, and then pairs with the watch so that you can download your data to Garmin Connect (which runs online, in a web page). It all works pretty well. Highly recommended and great value for the price.
