Environmental hazards like blowing sand, salt spray at the coast, or an accidental impact can cause irreparable damage to the lens and its delicate coatings. Damage of this kind is not a defect in materials or workmanship, so it is not covered by warranty, and often the only option is to replace the front objective lens at great cost.\u003c\/p\u003e\n\u003cp\u003eThe TP-58FT filter sits in front of the objective lens, so sand, salt and accidental contact reach the filter first. Because all Kowa spotting scopes feature a filter ring, adding this layer of protection is simple and, per Kowa, drastically reduces the risk of objective lens damage, prolonging the life and optical performance of your investment.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamage Prevention:\u003c\/strong\u003e Creates a physical barrier against sand, salt, scratches and knocks that can permanently harm the front objective lens.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepellent Coatings:\u003c\/strong\u003e The oil and water repellent coatings make fingerprints, sea spray and raindrops easier to clean away.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeamless Integration:\u003c\/strong\u003e Designed to fit the filter ring of the Kowa TSN-55 and TSN-550 PROMINAR spotting scopes.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cdiv class=\"DAV-accordion\"\u003e\n\u003ch3 class=\"DAV-accordion-Q\"\u003eWhat is the primary purpose of the Kowa TP-58FT filter?\u003c\/h3\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-accordion-A\"\u003e\n\u003cp\u003eThe Kowa TP-58FT is a \u003cstrong\u003eprotection filter\u003c\/strong\u003e.
