Page 3: General Overview
1. General Overview 1.1 Main Character 7x50 binoculars is a water floating model with illuminated compass. It has two ranging tools. The eyepiece Reticle Scale and the Calculator Dial can be used to easily determine you distance from an object if its size is known, or vice versa. The optics is made excellently in order to give the viewer brightness, exacting image clarity and unparallel true color of the image. -
Page 4: How To Use The Binoculars
3.1.2 How Binoculars works The light from the object or target you are looking at enters the binoculars through the Objective lens system (item 1, fig. 1). Due to the objective lens, the rays are converged to a upside down image. Then the light rays of the image pass through the prism system (known as the Porroprism) (item 2, fig. - Page 5 4.1.2 Rubber fold-down eyecups This is a long eye relief binoculars. It allows the eyeglasses wearer to see a normal image without taking off glasses.

When the Horizontal View Angle is bigger than the horizontal scale range (-40~+40 mils), a vertical line splits (for example: mast, chimney etc.) on the object can be selected to make the necessary estimated measurements in a step by step fashion. The sum of the value from each step is used to obtain the measured value.
- Page 7 4.2.3.B. when the Vertical View Angle is larger than the vertical scale range (80 mils), it can be measured in steps and the angle can be obtained by summing up the value of each step. (The process will be similar to the one that is discussed in the linear measurements in 4.2.2 B above.) 4.2.4 How to use the reticle to measure distance The distance measurement of a target can be calculated by using the mil reticule.
- Page 8 4.2.6. How to measure a object’s size (height and width) using According to the formula for distance measurement, you can calculate the height using: H = L × ω. When measuring the size, you first estimate the distance to the object, then measure the View Angle.
