The Celestron TrailSeeker Binocular series has been designed for high-level precision, accurate and versatile outdoor performance. The use of high-quality glass, advanced coatings and BaK-4 prisms make for incredibly clear, bright and clean images with true-to-life colours. Additionally, the use of ED objective lenses provides superior images that feature virtually no chromatic aberrations, increased resolution and a higher level of contrast. The binoculars are also lightweight and durable thanks to the magnesium alloy chassis and come with a convenience carry case for when they're not in use. These are the ideal choice for avid birders, wildlife watchers and outdoor explorers.
