I quickly learned the importance of a good bino on my brown bear hunt. We had to spend hours glassing, often without seeing anything, but would sometimes spot a bear during the few seconds it was moving in the open, before disappearing again. Seeing these things at long range, often in low light, requires clear glass, and I was very impressed with how the Swarovski 10x42 EL Range performed. It has incredible light gathering ability and the clarity is second to none. As with most of their optics, it's also very easy to glass with this bimo for long periods of time without getting a headache or suffering eye fatigue.
