SPECIFICATIONS:

"Well the first thing to say about the Ultrasports is just how snugly they fit in the hand - they're pretty compact for 8x42's, they feel light (and they are at 646g) and thoroughly well balanced, and they have a neat, unfussy open bridge design, meaning that you barely notice that you've got them with you....they're waterproof and fog-free, and very solidly put together....the image is sharp, bright and boasts a very natural colour tone.....what's most outstanding for binoculars costing less than £150 is the lack of edge softness - you get full value for almost all of the 129m@1000m field....focusing was precise and easy...All things considered its hard not to be really impressed"
