Being an avid bird watcher my dad recently leant me these brilliant binoculars for a safari a few years back, and though he paid £250 for them it was worth every penny.
They have 8X magnification meaning that as well as wildlife spotting they also come in handy when using them for general viewing such as mountain ranges or sightseeing. For underwater viewing they can reach a depth of up to five meters though I have not had a chance to test this. The gas inside the binoculars consists wholly of nitrogen, preventing fogging up due to temperature changes or high humidity. They have a great balance between the amount of light let in and size with big enough lenses to work in dimmer conditions. Even in these conditions there is no colour fringing or blurring on the edge of the view.
The viewing angle is an impressive 8.0°, the same as that of higher end professional sets. This makes it great for watching wildlife as you can see faster moving animals for much longer without having to adjust your position.
The compact body means that they are much easy to transport unlike a 8x42. It's an ideal set of binoculars for taking on safari, or even to a sports game without getting in the way. They are very comfortable to use and have very good grip in wet conditions.
The tough shell of the binoculars helps protect it from any knocks or scratches you might encounter.
Using the focus knob was easy and efficient, being able to focus from 8.2ft to its highest setting in a turn and a half. It was very well tuned and felt like it was gliding beneath your fingertips. There is a diopter adjustment for adjusting to your own eyesight which I found locked well without slipping out of focus.
