Took my new range finder out today and tried it in the areas I tend to hunt. For $399 I couldn't be happier. The glass does have a slight bluish cast but compared to comparable rangefinders I have had it is brighter and clearer. I had no problem ranging anything out to 800 yards. I was surprised that it did not return well off flat granite faces past 850 yards. Dark patches of trees/brush read out to 1050 yards if I held steady. Earlier in the week I was able to get readings beyond 1200 on white box cars. For my personal limit of 600 yard shots on game this should be perfect. It's a nice compact unit with nice tacky rubber grip. Shooting through limbs in the foreground the unit won't read beyond them very well. I assume this means it has a fairly wide beam. I don't think that will be an issue but maybe someone hunting from a treestand would. I shot this off my back deck at canopy level of the neighbors trees. Earlier in the week in snow it failed to read much past 300 yards, nothing unusual there. I wish I had a shot of it reading off an animal but California is absolutely devoid of deer. A tip I stumbled across. The plastic disposable cap that small propane bottles come with work as a perfect spacer to digiscope through with an iphone.
