Certified Pre-Owned Refurbished

These Certified Pre-Owned items -- including telescopes and accessories -- have been thoroughly inspected by the Explore Scientific Quality Control Team to ensure the item meets our high standard. The item is then repacked, often in a new box, and prepared for shipment.

Generally these items come from one of three sources: returned, often in like new condition; traded in on another item; or new but has blemishes and marks.

Certified Pre-Owned items carry the standard Limited One-Year Warranty on mechanical and optical systems; however, because these items are pre-owned, they DO NOT carry a cosmetic warranty.


The OMNI-4 is a precision reflex sight with a unique inverted design. This unconventional approach to an open sight limits the exposure of the lens to dirt and maintains the device’s functionality even when it is raining. The compact sight has unlimited eye relief, fully multi-coated optics and a high-efficiency bright red LED that guarantees exceptional battery life. It is both shockproof and splashproof for added durability.
