Some rangefinders have three lenses because they need to measure distance accurately. You can use the first lens to focus on the object, the second one to calculate the range, and the third to calculate the object’s size. The three lenses work together to give the rangefinder its measuring power. In the 3-lense rangefinder, you can consider the object’s size, distance, and angle. It allows for a much more accurate measurement than those rangefinders with two lenses. Benefits of 3-lenses Rangefinders for archery They provide more accurate measurements. They take into account the size of the object. Archers consider the distance to the target before releasing the arrow. Archers will consider the angle at which they view the target. This 3-lense rangefinder is easier to use and more durable than other rangefinders because they have fewer moving parts. Disadvantages of 3-lenses Rangefinders for archery They are more expensive than other types of rangefinders. They are heavier and bulkier than the rest types of rangefinders. They require more maintenance than different types of rangefinders. Overall, three-lens rangefinders are more accurate than other types of rangefinders. However, they are also more expensive and require more maintenance. A three-lens rangefinder is the best option if you are looking for a top-of-the-line rangefinder that will give you the most accurate measurements.
