i personally dislike the Tracker - its too automated and doesn't supply enough information... it beeps and blurps and blinks like crazy, and to me it wasn't that intuitive. (haven't fiddled with anything from BCA for about 4 years they may have made changes)
i have an Ortovox f1 and an Orto M2.... the f1 is analog, not as good for multiple burials and not as trick as some all of the new stuff but alot of old timers like em for their intuitiveness. the M2 is digital/analog and doesn't offer as much info as the beacons frm the last few years (d3) that really pinpoint the multiple situations well.
all of this said, the Tracker is widely used - and often by beginners. Any beacon you get you just need to practice practice practice with and you should be fine. its just not the beacon for me.
