Most binoculars are multipurpose instruments. If you are the type of person who does a lot of walking or traveling with their binoculars, then an ideal choice is a compact pair of binoculars.
When beginning a day of binocular observations, it is tempting to leave the binocular case in the car or at the base camp and rely on neck straps or other attachment mechanisms to secure the unit. When hiking or orienteering, binoculars will be very useful, but it is important to note that optics are very fragile, and so plastic lenses over glass ones, and a rugged case are probably going to be more important than high power, or the ability to use them at night. A larger objective lens makes sense during low light conditions, since it can capture more of the available light.
Glass also has a tendency to reflect as much as five percent of the light that arrives at its surface back towards the light source. When choosing hunting binoculars, look for phase corrected lenses. How well your binoculars will serve you in low light conditions is described as twilight performance.
Roof prism binoculars are so much easier to water and fog proof because of internal focusing. Treat your kids to a pair of inexpensive binoculars to explore the natural world around them.
