These are the type of binoculars that are used for boating or for watching any water sports from the shore like power boat racing. Each pair of marine binoculars needs to have certain features in order to make them the ones that you would use near or on the water. The first and most important feature of marine binoculars Australia is that they need to be water proof but there are different levels of water proofing. You want to make sure that the binoculars you choose are nitrogen-purged and completely O-ring sealed. What this means is that the air that is inside the body of your binoculars has been replaced with dry nitrogen gas. This dry nitrogen gas will prevent the internal optics from being foggy. This will usually happen when you have rapid changes in temperature. By having both of these specifications on your marine binoculars they will remain fog and water proof in any weather conditions or season.
By keeping your environment inside your optics moisture free it will also help to protect the inner workings from any type of corrosion. If you are worried that while on the boat that your binoculars may go overboard you need to choose marine binoculars that state they can be fully submerged for long periods of time in a reasonable depth. Your binoculars should also have a floating strap which will help you have time to rescue your binoculars and be able to continue using them.
The magnification is also important because you are going to be looking at objects that are farther away than you would on land so you want a high magnification but not too high. You should look for a magnification of seven times which means that your image will not be too unstable to look at and you will have plenty of power. If the magnification is too high the image can become unstable because any movement of the marine binoculars is also magnified. If you are using them on the boat most of the time the boat is moving and rocking so the images can be unstable because of the constant movement. If you do want a higher magnification of seven times you need to purchase marine binoculars Australia that have built-in image stabilization.
You also want to look at the objective lens size because the larger the object lens the more light that will be let in. This is important if you are looking at things with low light conditions. Most marine binoculars should have an objective lens size of thirty millimeters or fifty millimeters. You should also have a wide field of view as this will let you see more of the scenery at one time.
