Following on from the success of the Swallow 65mm and 80mm models, we introduce an even better optical performance experience with the Swallow ED 65mm and 80mm. From the extra-low dispersion (ED) glass objective elements to the dielectric coatings on the prisms, these telescopes perform to a level not seen in instruments at this price point before. A lightweight, yet robust, polycarbonate body material Two new telescopes join the Viking range! Following on from the success of the Swallow 65mm and 80mm models, we introduce an even better optical performance experience with the Swallow ED 65mm and 80mm. From the extra-low dispersion (ED) glass objective elements to the dielectric coatings on the prisms, these telescopes perform to a level not seen in instruments at this price point before. A lightweight, yet robust, polycarbonate body material, means that the 80mm version weighs in at less than the weight of two average 8×42 binoculars! The features don’t end there – dual focus wheels with different gearing enable a much finer control over focus accuracy at high magnifications where depth of field becomes very shallow. Both models are completely waterproof, come with stay on cases for added protection, and are backed by a 10-year guarantee. Take your wildlife viewing to the next level
