F1 still the best
Just back from a great 7-day back country ski trip in BC. The tour operator wanted everyone to have digital beacons so handed out Trackers to those of us with F1's. I was not impressed with the digital during the practice search. In comparison, the F1 'locked on' and I was able to easily locate the buried beacon. The reason given for going digital was its advantage in multiple burials but it seems to me that a) you should only expose one skier at a time on iffy slopes and b) beacon practice trumps relying on technology during an emergency. I carried the F1 as backup and will continue to use it for our small group outings.
