A limited edition of Steiner’s well-proven Commander binoculars is being offered to celebrate the company’s twenty-fifth anniversary. Such is the German company’s faith in their product’s rugged construction, that they back it up with a 30 year warranty. Using two-way valve technology to prevent internal condensation, the binoculars are waterproof to a depth of 5 metres – and even float if dropped accidentally overboard. Suggested retail price, a smidge under £400.00.
