Vanguard has been around for 25 years. They started with a high-quality line of photography
accessories like their excellent camera bags and low-cost, carbon fiber tripods. Then they
branched out into sports optics with several lines of spotting scopes and binoculars.
Endeavor ED binoculars are
Vanguard’s finest bird and nature-watching binoculars.
Vanguard Endeavor ED
binoculars are made with phase-coated BaK4 prisms. They also feature a
special anti-reflection AR Coating on all air-glass interfaces, which improves light
transmission efficiency and image quality.
Spirit ED Binoculars features ergonomic design and advanced optics. The
Spirit ED binoculars have a light transmission rate of up to 90%, resulting in a
crystal-clear viewing experience at about any time of day.
