Protection


Objective lens protection: By adding one of our high quality filters to the front of the scope, you can protect the objective lens from abrasive materials such as salt and sand - particularly if you are often spending time at the coast.

Why Protect your investment? The optical system on any spotting scope is the most costly to repair. By adding a low cost protection accessory to your scope, you can expand the lifespan and reduce the risk of damage especially if you use your optic in harsh environments on a regular basis - meaning no downtime waiting on repairs or servicing.
