I guess I'm old fashioned and I can see where the tracking gauge could be useful in some situations where you can't reach your buddy on the radio.
That being said, I was always taught to keep a visual view on your riding partners in case something goes wrong like an avalanche. If you do loose site of your buddy, by reaching them on the radio you can verify if he/she is OK.
Of course radios do have limitations in the mountains, so in this case a tracking gauge could be helpful. Like many things, it is a tool and a rider should be aware of it's limitations by not totally relying on it as the only form of monitoring each other. Sometimes there is no substitute for visual and verbal communication.
