Sweep the searchcoil carefully, especially when using around rocks and building 
foundations. Avoid hitting the searchcoil against hard, solid objects and surfaces. 

 

Keep your searchcoil slightly off of the ground during the sweep, especially when 
using in gravel or hard, rocky dirt. 

 

Always use a properly designed protective scuff cover on the searchcoil. (See 
"Optional Accessories" in the next section.) 

 

Remove and clean out scuff covers periodically to avoid buildup of mineralized dirt 
particles which will affect performance. 

 

The searchcoil is waterproof and can be submerged in either fresh or salt water. After 
the searchcoil is used in salt water, rinse it and the lower stem assembly well with 
fresh water to prevent corrosion of the metal parts. 

 

The searchcoil is waterproof but the electronics are not, so always prevent any 
moisture or water from entering the control housing and never allow the cable 
connectors to become submerged in water. 

 

If working in or near water, or if there is a possibility of rain, use a protective weather 
resistant pouch or plastic bag to cover the control housing. Make sure it can "breathe" 
in order to ensure against condensation buildup inside. 

 

After each use, clean the detector with a soft cloth to remove dust, moisture, or other 
contaminants. 

 

When transporting the detector in a car during hot weather, store it on the floor of the 
passenger compartment if possible. Using a carry bag gives additional protection. In 
any case, never allow the detector to roll around unprotected in the trunk or back of a 
pickup truck. 

 

Protect your detector from dust, moisture, and extreme temperatures during storage. 

 

When shipping, use the original factory carton or similar heavy-duty container and 
provide a minimum one inch of padding around all parts. 

 

Treat your detector as you would any sensitive electronic instrument. Though 
ruggedly constructed and designed to withstand the demands of normal treasure 
hunting, proper care is essential. 

 

 

OPTIONAL ACCESSORIES 

Tesoro metal detectors and genuine Tesoro accessories are sold only through independent 
Tesoro Authorized Dealers, who are almost always metal detectorists themselves. They can 
answer your questions about your Tesoro detector, what accessories may be helpful, and 
about metal detecting in general. See your Tesoro Authorized Dealer for more information 
and prices on optional accessories.  

Scuff Covers 

We highly recommend using a scuff cover to protect your searchcoil at all times. The scuff 
cover for the Golden µMax, fitted with the 9x8 searchcoil, is Tesoro Part # SCUF-9x8.  

Searchcoils 

The 9x8 concentric searchcoil provided with the Golden µMax is designed for best all-around 
performance. Optional searchcoils may add to your detector's performance.
