VIP Unconditional Lifetime Warranty Details

The Vortex Kaibab HD is a remarkably bright binocular for long distance viewing. 

An excellent choice for stargazing, observing ships at sea or similar. 

Features include premium HD (High Density) extra low dispersion glass and fully multicoated optics for high resolution views with negligible chromatic aberration. 

The large size and high magnification makes this a binocular best used with a tripod or monopod (a good quality tripod adapter is included). Nevertheless it still has rugged rubber armour and ArmorTek lens protection so can be used with confidence in the field, regardless of the weather!
