Marine Binoculars -
A Look at Some of the Best

So Which Is The Best?

Not such an easy question to answer! Ignoring price for a moment, the finest binoculars made may not be the right fit for everyone. In addition to the easily determined specifications, there is the more difficult subjective question of "Are these the right binoculars for me?"

So, we will chart what I believe to be the top 2 contenders for the best marine binoculars produced today. We will look only at the specifications and leave the subjective reasoning to the individual user.

Marine Binoculars Comparison Chart
Specification Recommended Fujinon Steiner

This feature has become quite common place especially in those binoculars that have an integrated compass.
Yes Yes
Armoring Yes to this.
A heavy rubber compound that is molded to the outer body of the binoculars. Since things on boats tend to get bounced and tossed around much more than they do on dry land, this coating will prove invaluable.

Size & Weight Personal Preference.
Heavier binoculars may give you a more stable viewing advantage, lighter binoculars will allow long usage without feeling like you have brick tied around your neck.
