It makes sense to compare the Excursion EX with the Legend 8×42 Waterproof, since the latter is only about $25 more expensive. The features which should be looked at, are optics, weatherproofing, Field of view and weight.
Optics: Both the 8×42 Excursion EX and the Legend 8×42 Waterproof Binocular have their roof prisms made from BaK-4 optical glass, coated with PC-3 phase coating, but only the Legend 8×42 Waterproof Binocular has SHR (Super High Reflection Coating) as well. As for the lenses, both are fully multi-coated.
Weatherproofing: Both are waterproof and fogproof, but only the Legend 8×42 Waterproof Binocular has Rainguard added to the outer lenses as well, which is a big benefit in wet conditions.
Field of view (FOV): The 8×42 Excursion EX boasts a huge 7.9 degrees (414.75 ft@1000 yards), the best in this price class, far outstripping the Legend 8×42 Waterproof Binocular, which can manage only 6.3 degrees (330.75 ft@1000 yards).
Weight: At 625 gm./22.05 oz. the 8×42 Excursion EX again far outstrips the Legend 8×42 Waterproof Binocular, which is rather heavy at 853 gm./30.09 oz.
The way Bushnell has marketed the 8×42 Excursion EX it is clear that it was manufactured for hunters and/or people who like to watch wild animals in the woods. Obviously that does not mean that it is not suitable for other purposes as well. Choosing between the 8×42 Excursion EX and the Legend 8×42 Waterproof Binocular is a matter of deciding whether the benefits of better optics and weatherproofing justify the slightly higher price. On the other hand, there’s nothing wrong with the optics of the 8×42 Excursion EX and this binocular excels in excellent FOV and weight. Both are good binoculars, each offering good reasons why they should be bought!
At 8×42-binoculars-150 the Excursion EX is compared to other binoculars in the same price range (Vortex and Hawke Frontier).
