"Direct Sync" means Ascent will read data directly from the device when it is attached via a USB cable or when the wireless Garmin ANT Agent is installed (free download from Garmin). Newer Garmin devices (705, 605, Colorado Series) appear as mass storage drive on the mac when their USB cables are plugged in. These devices produce files (gpx or tcx) that can found on the mass storage drive and easily imported into Ascent without any other conversion utilities.

Other Garmin USB devices may work via direct sync but have not been tested. Please download the application and try with your device to determine compatibility before purchasing.

If you have an exercise data recording device not listed above and you are interested in Ascent, please send email to and specify your device and activity (cycling, running, hiking, etc.).
