chose this rangefinder after comparing it to the others. The layout of the buttons and focus wheel is different from the others I see on the market. I love the large rubber focus wheel, it's very easy to adjust with your index finger and can be operated with one hand. I can use it very quickly and easily on the first use. It's ultra light and small so it fits in my pocket. It has a durable hard shell with a smooth modern polish and looks nice and clean. My friend has one with a rubber surface, it catches a lot of dust and fingerprints. This range finder has different measurement modes with vivid feedback. It measures horizontal distance, vertical distance, angles, inclines, speed, etc. With a one-touch button, you can easily and quickly switch between modes. The result is accurate and the image has a high resolution, the image quality is still great even with a 6x zoom. It's no different with my friend's hundreds bulk range finder, that's a really good deal. What's more, it comes with a cloth bag for carrying, which provides good protection, and there is also a wrist strap so you don't have to worry if it accidentally falls. I am very lucky to have found this product, I am really satisfied with the quality and the good price. Highly recommended.
