Review on NewDoar 25x30 Zoomable Monocular Vintage Pirate Telescope: Waterproof Aluminum Alloy and Adjustable Optics for Travel, Navigation, Sailing, Voyage, View Watching, and Games by Tay Fair

That's what I expected. Something light and comfortable for walking, etc. With such a powerful lens, you have to get used to focusing and staying still. If you want to see a lot, take binoculars. But good for occasional use. For example, you probably won't enjoy regular bird watching. Too much movement and little aim.
