Excellent units. I've used the Mk II and Reap-IR much more often, and you simply can't go wrong. You will be hard pressed to find a better unit with the same magnification. If you can get away with less 'zoom,' the Mk II and Reap will do you just fine. You will find that judging distance with a thermal can be challenging, and getting closer to your target will improve your night hunting effectiveness. Either way, buy a Triji and don't look back.
