Summary: Bought this for my husband who only has one good eye. He is delighted with it and finds it very good and easy to use. It is sturdy and far better than the previous, cheaper, one I bought him which broke the first time he used it, so worth paying a higher, but still reasonable, price for. A little bulky for trouser pockets but with it's own carrying pouch it is handy to pop into a rucksack for a day out.
Summary: My objective was to find a lightweight optical device for use while walking and this monocular is ideal. The device is well made, ergonomically shaped and fits comfortably in the hand. There is a retractable eyecup which when extended takes the overall length to 130mm. The maximum barrel diameter is 57mm. This monocular weighs 250grams including the soft case [which has a belt tag]. The optical performance is good for a small device.
