On a bright sunny day I can get readings out to 1100 on rocks and trees with my Leica 1200 CRF. On a more overcast 1200 is do-able. But if you did have the money buy the Swaro, I guess it can range a whole lot further.
Overall I do like my Leica 1200 Crf. Its small fits in your shirtpocket, has twice as much battery life than the swaro. If you do any night hunting it has a illuminated led reticle and readout, which is nice in the daylight too. Optics are good, not as bright as the swaro i checked out.
If you do any bowhunting you will like the minimum ranging capabilitys of 10 yards, I dont think the swaro will go that low.
Whatever you do stay away from Leupold rangefinders, made that mistake already.
If you ask around for good prices you can save almost $100 dollars off the price at cabelas of a Leica 1200 crf. Which is listed at $599.99
