I'm not sure how you tell which model you have, but it's a Gen 1 or 2. It's in great shape. I've gotten ranges out to 2400 on river bluffs/ barns. Hitting sub-1,000yd targets is easy. You know what they are capable of with the onboard atmospheric sensors and ballistic calculator. Simple to use. Living at 1,000ft elevation and hunting out west, it has been very valuable. $900 PayPal net to me. I'll pay shipping in lower 48.
