Step 1
Understand the difference between nautical binoculars and those used for bird-watching or general use. Nautical binoculars are especially designed to reduce glare and other weather conditions on the water while magnifying the horizon.
-
Step 2
Look at how binoculars are classified. There are two numbers. The first is the magnification. A number of five, for instance, means objects are five times larger than in real life. The second number is the objective. The higher the number, the brighter the object.
-
Step 3
Determine the difference between the two numbers to pick the best nautical binocular for your use. You want the objective to be four times larger than magnification for daytime use. Go for at least seven times the difference for night.
-
Step 4
Remember that you need to hold a nautical binocular steady. Make sure the size and weight fits.
-
Step 5
Examine price ranges. Nautical binoculars cost roughly $300 and up, depending on the manufacturer and features.
-
Step 6
Try out several styles, manufacturers and magnification combinations. The investment makes it worth the time to pick exactly the right instrument.
