The product serial number is typically located at the front end of the binocular axis (between the objectives), on the underside of the axis, or sometimes on the objective lens ring depending on the model.
First, remove dust and loose dirt with a brush or air blower. Then use a soft, damp cloth or dedicated lens tissue to wipe the lenses. Avoid using rough materials that could scratch the glass or coating.
The Steiner Heritage Warranty generally covers riflescopes, binoculars, and sights for the life of the product against manufacturing defects. It is transferrable and does not require a warranty card or receipt, though specific terms may vary by region and product line (e.g., electronic components often have different coverage).
On Porro prism models with Sports-Auto-Focus, you adjust each diopter setting once to your eyes. After this initial setting, everything from approximately 20 meters to infinity remains sharp and clear without the need to refocus.
Most professional Steiner series (like the Commander and Navigator) are pressure-waterproof and nitrogen-filled to prevent internal fogging, capable of withstanding submersion up to varying depths depending on the specific model specs.
