Bird watching telescopes can be roughly divided into two types: binoculars and monoculars. Binoculars are mostly 7~10 times, suitable for hand-held viewing of relatively close birds, and are an essential "weapon" for every bird-watching enthusiast. Most of the monoculars are 20-60 times larger, which is suitable for watching long-distance and relatively slow-moving birds. In addition, the monocular needs to be used with a tripod, usually about 4-6 people can use one.

Personally, I have always bought binoculars. Binoculars can be simply divided into two types: Porro type and roof type. Porro type telescope: simple structure, easy to process, but bulky and heavy. Roof type telescope: small size, relatively light, but difficult to process, the price is higher than the Porro type.

We often see numbers such as 8*42 or 10*42 in binoculars, where 8 or 10 is the magnification of the telescope eyepiece, and 42 is the aperture of the objective lens. What is the multiplier? Simply put, magnification is the number of times the object is brought closer. For example: a target 700 meters away, if viewed with a 7x magnification telescope, it presents a scene equivalent to a distance of 100 meters in front of the naked eye.
Tips: Binoculars usually choose 7-10 times. When the magnification exceeds 12 times, due to the shaking of the hand, the image will be unstable and the observation will be uncomfortable. Therefore, a tripod is required to support it, which will lose the greatest effect of binoculars: flexibility.
If you want to buy binoculars, if it is for general field observation enthusiasts, you can choose the SECOZOOM practical series of the telescope brand, which is cost-effective and of good quality. As for specializing in this line of work, it is essential to develop a set of advanced professional telescopes.
