Product Information

Michelin xeobib brand new slightly damaged tyre, this tyre was removed from a ex demonstator as it had been caught on a drawbar and slightly damaged the lugs, the tyre is in perfect serviceable condition , the tyre has only done aprox 50hours so is like new, pleaes take a good look at the pictures, 1 only Nitrogen is a chemical element and a colourless, odourless and tasteless gas. It contains very little humidity and is therefore used to "purge" binoculars and spotting scopes of the high humidity air that is part of our environment. Due to the low humidity factor, nitrogen prevents condensation from forming on the internal lenses of optical instruments during phases of rapid temperature change. Furthermore, because nitrogen is purged into the optical instrument at slightly above atmospheric pressure, dust and other miniscule particles are prevented from entering the housing. Long eye relief design The eyepiece housing looks to be made from aluminium or something similar and the twist-up eyecups look to be made from a hard plastic, which has then been covered in a thin soft rubber coating. They are fairly comfortable even when pushed quite firmly against your face. The ocular lens has a diameter of 17mm, whilst the eyecup has an external diameter of 34mm.

The Pentax A-series of binoculars are a more compact, portable and durable version of the S-series. They feature new fully multi coated lenses, phase correction, BaK4 prism, and a new enhanced light transmission coating to provide crystal sharp images and superb contrast. sold in pairs 167020 mitas caseings all in very sound condition ,BUT not a lot of tread, ideal for yard work or grasswork where you don't want to cut up the turf, sold in pairs , 8 available, sold as pairs and priced as pairs For a compact roof prism binocular, these 9x28 Pentax DCF LV binoculars have a fairly common single hinge design with a central focussing wheel and an internal focus lens construction. I really like the fact that the objective lenses are set quite deeply within the ends of the barrels (about 5mm) as this can really help protect your lenses when you are out in the field.Radial tyres do however tend to be more expensive than crossply alternatives, so could be viewed as an investment that will pay off in the long run. PENTAX binoculars take quality optics to the next level by applying a new, optimised film-deposition technology on lens and prism surfaces resulting in increased light transmission which creates bright images with accurate colour rendition BaK4 prisms Store your tractor indoors: Exposure to sunlight UV will damage your tire over time and shorten its lifespan. Pentax waterproof products are fully sealed and purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions. With a JIS Class 6 rating, Pentax waterproof binoculars can even be submerged in up to 3 feet of water. Inner Focus Optics Design

the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. PENTAX applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world. New Enhanced Light Transmission Coatings This is one of the weaknesses you have to accept when choosing a compact binocular. In poor light, you will not perceive as bright an image as a larger binocular with the same or similar magnification. here I have a very good set of 18.4x26 ( rears) + 411400x20 ( fronts )turf wheels and tyres off a same 70, deutz, lamborgini, and some ford tractorsIf you are willing to try a 7 x 26 reverse porro prism binocular here is one that is generally considered the best of the bunch. It is very good and costs about the same as the Pentax but is not waterproof. I have one too. I like it quite a bit and optically it is better than the Pentax 9 x 28 and it has a much wider Field of View but I'd rather use the Pentax. I like it's ergonomics and ease of use better. Thus it stands to reason that if you are generally going to be observing objects at longer ranges, a 10x or perhaps even a 12x magnification might be the right option. Although, having said that, there are still many other factors and consequences brought about by the higher power that you still need to take into consideration before making your final choice: Field of View Think of the objective lenses like the windows in a house. Large sliding glass doors on your patio are able to capture and let in much more light than a tiny attic window. a pair of 4806528 vredestein traxion tyres with about 60-70 percent tread, on 8 stud ford tm or newholland rims, all in good condition, sold as pair, may seperate tyres The long eye relief offered in all PENTAX Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain. Other Features
