Best Compact Marine Binoculars
Navigator Pro 7×30
Steiner has come up with an amazingly light, small, yet feature-packed set of binoculars. Image stabilization, electronic compass with 7 x 50 magnification, in a pair of bino’s that can fit easily into a pocket.
Steiner has included their autofocus technology along with CAT optics. This means that images are crisp, sharp and always in focus in bright or dim light.
This compact unit also boasts a range finder! This is especially useful when identifying hazards or waypoints. This feature is not absolutely accurate and does need some mental arithmetic. Take the known height of an object you are looking at
E.g. a lighthouse (150 feet high) and appears to be 15 points in the range finder. So you divide the height of the lighthouse by the points (150 / 10) and get 10. This means the lighthouse is 100000 feet from your current position.

- Magnification Level: 7 x 50

Buyer's Guide for Marine Binoculars
Choosing the right magnification level
Most people think that the greater the magnification a pair of binoculars have, the better they are. In actual fact, this is not necessarily the case.
Unless your binoculars are mounted on a tripod, or other stable platforms, every jiggle of your hands will be magnified in proportion to your binoculars magnification.
Choosing a magnification level between 7x and 10 x is a good range. This will ensure that even if your platform is not stable your image will remain crisp and in focus.
Lens size
This is one of the rare cases where bigger is actually better. Larger lenses allow more light in and as such increase the sharpness and clarity of the image. This is especially important in marine environments where you have to contend with fog, rain, dawn, and dusk.
If you choose a compact pair of binoculars, this will limit the lens size and have a significant impact on the image quality you can expect in trying conditions, so make sure the space saving advantage is worth the trade off.
