I was not impressed with the original Tracker or the Tracker HD. The lack of resolution was a deal breaker for me. I just acquired a Tracker 2 HD and I'm quite impressed thus far. For game recovery or a handy thermal spotter that will fit in a jacket pocket, Leupold seems to have gotten it right with this one. The pics don't do it justice, It's much clearer looking though the device. 1.7 power.
