Used Metal Detectors for Sale: What Open Box Means Here

Many shoppers reach this page searching for used metal detectors for sale. What we list here are open box units: metal detectors with damaged or opened packaging, offered at a reduced price. Full manufacturer’s warranty included. The packaging is the reason for the lower price, and each unit comes with the manufacturer’s standard box contents for that model. The page covers metal detectors and pinpointers, so it is worth checking before you pay the new-in-box price for a model you already have in mind.

Open Box vs Used Metal Detectors

A used metal detector has been owned and hunted by someone else, is usually sold privately, and its warranty may have run out or may not transfer to you. An open box detector from us is a metal detector with damaged or opened packaging, offered at a reduced price. It comes with the full manufacturer’s warranty, the standard box contents for that model, and the same help from our staff as any new detector we sell. If you came here looking for a used metal detector to save money, open box gives you the lower price without the guesswork of a private sale. Not sure what a fair price for a new machine looks like? Our metal detector pricing guide gives you the baseline to judge any discount against.

How Open Box Works

  • Why the price is lower: the packaging is damaged or has been opened, so we offer the unit at a reduced price.
  • What each listing shows: the model, the coil or coils, and the full box contents for that package, so you know exactly which configuration you are buying.
  • How to compare: check the same model in its new-in-box listing or model collection to see the saving and confirm the configuration suits your hunting.

Warranty on Open Box Metal Detectors

Full manufacturer’s warranty included. An open box unit carries the same manufacturer warranty as a new unit of that model, and we help with product registration the same way we do for every new detector. Warranty length depends on the brand and model; call or email us if you want to confirm it for a specific unit.

What Comes in the Box

Every open box unit comes with the manufacturer’s full standard box contents for that model, listed on its product page: the detector, its search coil or coils and the accessories the manufacturer packs with it. Our free field kit comes with new detectors; open box units are priced lower instead.
