Even though our Signature Series binoculars have consistently triumphed during side-by-side comparisons with $1,000 plus brands, we’ve made them even better this year. We’ve applied a special chemistry of phase-correction coating to the prisms to boost the resolution and color-correctness just that little bit more. As always, Signatures boast the very best precision ground glass and roof prisms, a perfected optical system, and optimum lens multicoatings.
