My friend is getting into BC this year and is in need of a beacon. I have my Tracker and was thinking of upgrading to the tracker 2 and selling my Tracker to my friend. Currently the tracker 2 is on sale for $249 so i thought why not. I've looked up reviews of the Tracker 2 and apparently is a good improvement. Is the tracker 2 a worthy upgrade from the older model or should i be searching for something better?
