Orion 51847 Otter ED Waterproof Binocular, Black

hello I'm Ken with Orion telescopes and binoculars and this is the Orion 10 by 42 otter edy birding binocular so first of all it's 10 magnification 10 by 40 to 10 times closer and a 42 millimeter lens to suck in the light that you need when you're birding in lower light conditions in the treeline on a gray rainy day and it also works very well for just general purpose hiking and nature viewing it's lightweight magnesium alloy body keeps it very lightweight the the open hinge design here gives it structural rigidity in the front in the back it's hinged and holds its collimation but it's open in the middle so it keeps it a little bit lighter weight and the feel of the binocular is actually quite nice I like wrapping my fingers around it like this and I have a nice solid connection to the binocular when I'm looking through it it's got a 5.6 degree field of view and just over 15 millimeters
