DTS Tracker by far...How many times do you and your friends practice searches with your avalanche beacons? Yeah right, when the gett'in is good you start carving not checking batteries and walking around snow fields trying to find some other frigin buried beacon. The Tracker let's you be lazy without risking your life. I did field tests with folks who never heard of an avy beacon let alone ever get out in the wilderness. With less than 3 minutes instruction they could easily locate another beacon when using the Tracker. Then I tried with other "conventional" beacons and good luck! When struck by a panic situation don't you think the easier, more intuitive device is the way to go? I did over- whelmingly and most of my friends did also. The Tracker has other smarts as well. The system prompts you for confirmation every few minutes when you are in search mode (ie. receive instead of the default transmit). If you happen to be hit by a subsequent avalanche and are trapped your beacon automatically converts back to send mode so that other searchers may find you. I don't think the other beacons have such options. Other numerous options I won't mention but the unit is well built and well thought out. Not to mention, the tracker tells you remaining battery percentage on start-up.
