Tesoro Metal Detectors: Parts, Manuals & Replacements

Tesoro began making metal detectors in 1980 and closed in 2018, and many Tesoro detectors are still in the field. We do not sell new Tesoro detectors; this collection holds the genuine Tesoro parts we carry for owners who want to keep theirs running: a 12 x 10 inch open coil cover, an 8.5 inch closed coil cover, grommet washers, arm bracket nut and bolt hardware, and the digital Tesoro Lobo instruction manual. If your Tesoro needs replacing, the guide below matches the way you hunt to a current detector we carry, with an active manufacturer warranty.

Tesoro Parts and Manuals We Carry

Tesoro built its name on light, simple detectors, and owners still search for the small parts that keep them working. These are the genuine Tesoro parts in this collection:

A coil cover protects the bottom of the coil from wear on rocks and gravel, so we recommend replacing a worn cover before the coil itself is damaged. Measure your coil before you order: the covers are sized by coil, not by detector model. The grommet washers and the arm bracket nut and bolt are small mounting hardware that is easy to lose in the field. If you are not sure a part fits your Tesoro, call or email us with your model and coil size before you order.

Replacing a Tesoro: Match the Way You Hunt

When a Tesoro needs a part nobody has, the right replacement depends on how you used it, not on the model name. Current detectors from the brands we carry show a digital target ID, and many are waterproof. These are the current detectors we recommend for each kind of hunting, all with an active manufacturer warranty.

Coins, parks and yards

If a Compadre, Silver uMax or Golden uMax was your coin and park detector, we recommend the Nokta Simplex LITE or Simplex ULTRA, both single 15 kHz frequency detectors, IP68 waterproof to 5 m (16 ft), at 2.6 lb (1.2 kg) with the coil. On land only, the Garrett ACE 300 (8 kHz) and ACE 400 (10 kHz, with Iron Audio) give you a 0 to 99 Digital Target ID with five search modes. Browse more in our beginner and intermediate detectors.

Coins and relics

If you hunted coins and relics in iron-heavy ground with a Cibola, Vaquero or Tejon, start with our relic and treasure metal detectors. Among Fisher's single-frequency detectors, the Fisher F75 runs at 13 kHz with a Static All-Metal mode and DST mode to suppress electrical interference.

Gold prospecting

If you prospected with a Lobo SuperTRAQ and want a VLF gold detector, the Fisher Gold Bug Pro runs at 19 kHz with Ground Grab and manual ground balance, and the Gold Bug 2 runs at 71 kHz for the smallest gold. See all our gold detectors, including pulse induction models.

Beaches and water

If the Sand Shark was your beach and water detector, browse our waterproof metal detectors. The Simplex LITE and ULTRA go to 5 m (16 ft); for salt beaches and wet sand, look at the multi-frequency and pulse induction detectors in our beach metal detectors collection. Our Tesoro Tiger Shark vs Sand Shark comparison compares two Tesoro beach detectors.

Tell us your Tesoro model, the coil it has and where you hunt. If a part we carry fits, we will tell you; if it is time to replace the detector, we will recommend the closest current match for the way you hunt, and our contact page has our phone number and email.

Is Tesoro still in business?

No, Tesoro is not still in business: Tesoro closed in 2018, so you cannot buy a new Tesoro, and we do not sell new Tesoro detectors. Tesoro began making detectors in 1980, and many still work. For owners who want to keep theirs running, we carry genuine Tesoro coil covers, grommet washers, arm bracket hardware and the digital Lobo manual in this collection. If your Tesoro needs replacing, our beginner and intermediate detectors are a good place to start, all with an active manufacturer warranty.

Are Tesoro metal detectors still worth using?

Yes, a working Tesoro metal detector is still worth using for coins, parks and relics, and many owners like how light and simple it is. The limit is parts and support: we carry a small range of genuine Tesoro parts, and repairs beyond those parts can be hard to arrange. If you want a detector with an active manufacturer warranty, a digital target ID and, on many models, a waterproof build, see our beginner and intermediate detectors; our best metal detectors for beginners guide compares them.

What's the best modern replacement for my Tesoro?

The best modern replacement for a Tesoro depends on how you used it. For coins and parks, we recommend the Nokta Simplex LITE or Simplex ULTRA, both 15 kHz and IP68 waterproof to 5 m (16 ft), or on land the Garrett ACE 300 or ACE 400. For coins and relics, see our relic and treasure detectors. For gold with a VLF detector, the Fisher Gold Bug Pro runs at 19 kHz. For beaches and water, see our waterproof detectors. Tell us your model and where you hunt, and we will recommend the closest match.
