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 Silver µMax fitted with the 8" searchcoil, is Tesoro Part # SCUF-8R-B.
Searchcoils
The 8" concentric searchcoil provided with the Silver µMax is designed for best all-around
performance. Optional searchcoils may add to your detector's performance.
Smaller searchcoils give better “target separation”—that is, more distinct target response for
metal objects buried closely together—which is very useful when hunting trashy sites. Very
small searchcoils can deliver the best response and depth to small targets such as fine gold chains
with some sacrifice in depth on larger objects. Larger searchcoils give a wider sweep, covering
more ground, and provide greater depth especially on larger objects; however, they may not
detect some very small objects such as half dimes and will have difficulty in very trashy areas.
Wide scan searchcoils ignore ground mineralization better than concentric searchcoils and may
offer improved performance in extreme ground conditions.
Selecting the right optional searchcoil depends on factors such as what you are searching for and
search site conditions. No one searchcoil is better than all the rest. Several optional
interchangeable searchcoils are available for the Silver. They are all easy to mount and require
no special tools. See the following list of these searchcoils with the Tesoro part # and
description.
