Yup, I used a Sig rangefinder this past season. It was nice, light, and would range quicker, farther, and more reliably than my Leupold Full Draw 4, but I had to swap batteries once or twice.
I bought the Leupold immediately after it came out, and I think I've changed the battery once. Which is weird because both are rated to the same number of measurements.
Also, all the Sig models are IPX4 rated for waterproofness (didn't think to check when I bought it) which is an absolute no-go here in the SE where it rains every day during archery season. The Leupold is IPX7, which IMO is what any good rangefinder should be seeing as how critical it is to a hunt.
