Focus Scientific
Used Equipment
All used equipment is inspected, tested and adjusted by our expert staff - the same great Focus Quality Assurance we provide with new products.
Optics and mechanics are warrantied by Focus Scientific for one full year. Electronics are excluded from warranty, but are tested to work.
We're always looking for used products for consignment or possible trade-in. Turn your unwanted equipment into money, or new equipment via Focus Bucks - leave on account for future purchases. We're sorry, we cannot provide firm valuation of your used equipment by phone or email; in-store evaluation required. We appreciate your understanding.
While we try to keep this list up-to-date, there may be instances where a product has been sold, and its removal from the website is pending. We apologize for any inconvenience.
