Those who seriously want to carry out observations at a high level need correspondingly powerful optics. Our APM MS 100mm binoculars already have 3x as much light-collecting area as 50mm binoculars. This results in a significantly increased resolution, limit size (astronomy) and magnification in the terrestrial area. New fields open up for the nature observer, as distant objects remain recognizable even in difficult light situations. The amateur astronomer will appreciate the increased object brightness, which makes detailed observation much easier. The price-performance ratio is excellent!

The large 4 "ED optics are modern multi-coated, as is the BAK-4 prism system. This enables sharp, high-contrast and bright object imaging, even in unfavorable light conditions. Our model 25x100 offers an AP of 4mm, an optimal value for long-term detailed observations. A tripod is recommended for observation (adapter included).

The APM Magnesium binoculars use high quality ED glass (FK61) as well as BAK-4 prisms for maximum contrast and highest sharpness over the entire field of view. Special coatings on all optical surfaces eliminate residual reflections and ensure lifelike colors. With a pupillary distance of 16mm, the eyepiece construction is very suitable for people who wear glasses. The rubber eyecups can be turned inside out.

The entire system received IPX-7 certification for protection against the ingress of water. Our glass is completely protected against rain and immersion in water, so completely weatherproof. The magnesium housing is very light and yet very robust. A rubber armoring is attached to the housing, which further protects the glass and gives you a secure grip and hold.
