SWAROVSKI EL The EL binoculars combine maximum functionality, innovation and design. The unique wrap-around grip enables comfortable operation even with one hand. Low weight and excellent balance make light work of observation over long periods. The sophisticated top-class optical system delivers high-contrast, lifelike image quality. In the EL series, Swarovski Optik uses high-quality technologies such as the SWAROBRIGHT coating for maximum colour fidelity across the whole light spectrum or the SWAROTOP and SWARODUR coatings for bright, high-contrast images. The non-stick effect of the SWAROCLEAN coating on the outer surface of the lens makes cleaning objective and eyepiece lenses considerably easier, above all when removing dried-on mineral residues (e.g. water marks due to condensation), insect repellents and tree resin.
