tracker is a great beacon for sure. sets the standard.
the Barryvox is superior, IMO, because of the ability to switch between analog and digital. ALlows you to pick up a signal before the tracker does and I find pinpointing much easier and accurate in analog mode.
Plus....It is SO MUCH SMALLER. Tracker is clunky as hell.
Check out the difference
Anyone looking at getting a beacon...the barryvox is smaller, usually cheaper ($251 at REI right now), has a better on/off switch, better harness, allows for the user to switch between analog and digital at the touch of a button, allows the user to customize the settings, and has better battery life (in my experience) than the tracker.
The only area where some people find it confusing is in multiple burials in digi mode. IMO...again the barryvox is much better. You can switch right over to analog and use it before switching back to digi.
The Tracker is a great beacon, no question, but why not get the best?
