About this deal

We also checked out the built-in compasses for ease of reading, damping, accuracy and use of the night light. We had an agonising wait for a clear night after they arrived, but now we all race up to the loft to look at the moon, M42 and the Pleiades every chance we get. They feature a range finder for calculating distances (note the graduated ring behind the right-hand objective lens), and are non-floating although a swim strap is provided.

These good-value, rubber-coated binoculars have eye adjustment on both lenses and fold-back eyepieces for spectacle wearers. A 7x magnification binocular is considered the ideal marine or low light binocular, this size would be perfect as a gift when you’re unsure of what the binoculars would be used for. A large diameter is important as it helps to pick up an image from a moving deck and for night vision when pupils are fully dilated. Being able to read a compass bearing is also a useful feature, whether for determining position or deciding if there is a risk of collision from a closing vessel. To increase the exit pupil in the example above, we could, of course, increase the objective lens size.The quality of image produced is significantly better than standard focus free binoculars as this model uses BAK4 quality prisms and multicoating to improve light transmission and definition. The Ostara Elinor2 series is designed to give exceptional clarity and brightness and features upgraded optics over the original award winning Elinor range. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. Robust body, comfortable around the eyes due to the softer viewing aperture and very clear results with great details. High quality powerful binoculars with an exceptional combination of optical performance, features and value.

The compass bearings did differ slightly between different makes, but usually only between 2° to 4°, and some of this could be accounted for by boat swing. I bought these to replace a similar pair I broke by standing on them whilst fighting with a wayward sheet.Please select at least two products to compare Compare items Remove All has been added for comparison; please select at least one more product to compare it with. The Visionary Classic range of binoculars provide excellent value for money without compromising image or build quality.

Each tester had their favourite, often influenced by the shape and size of the binoculars: a bit like shoe size. Marine-3 7x50 binoculars are designed and manufactured to meet the toughest performance criteria demanded by enthusiasts and professional users observing from on-board a vessel or onshore looking out to sea.At home, I also like to use my 7x50 in combination with either a giant high powered binocular or my telescope that I have set up on the tripod next to me. The prisms have ‘floating’ mountings: they are fixed with a durable, flexible silicone material to protect the valuable optical components inside. Great value I bought the Binoculars for observing at night, unfortunately we’ve had clouded evenings since we got them, however daytime use has been great, clear vision and very lightweight. Fold down rubber eyecups are designed for comfort and allow spectacle users to view the full field of view.
