The Pre-Focus system on these binoculars means that you do not have to fiddle around trying to focus to get a clear image. The focus has been pre-fixed at the factory and everything from approx. 25 metres to infinity will be in focus for people with normal eyesight, even spectacle wearers.
Easy to use no fuss, no focus means you can pick them up and see instantly without having to try and focus while the boat is tossing around and one hand is busy hanging on. They are waterproof so will take all the spray and even a dunk in the ocean if you accidentally let go of them (rule number one is always put the strap around your neck). Perfect for whale-watching as you won't have you spend time trying to focus before the whale disappears!
They are light and the 50MM objective lens diameter means they are good for low light conditions i.e.,early morning and late evenings, even at night.
