Tesoro 12" x 10" Widescan Epsilon Search Coil with 3 ft Short Cable. This white DD coil is made for the Tesoro Cortes, DeLeon, Golden UMAX, Silver UMAX, and Outlaw series Metal Detectors.
Accessory Coils:
To get the most out of your detector, you may need a different coil. To match an accessory coil to your needs, you will need three pieces of information: Coil Family, Coil Type, and Coil Size. See Coil Info below to ensure the proper part number for your new coil.
Epsilon Coil Family:
The Epsilon coils have 5-pin connectors.
Coil Type - Widescan / Double-D:
Widescan coils use two D-shaped antennas that are placed back to back. Because of this configuration, they are often called “Double-D” coils. The widescan coil is less affected by mineralization than the concentric, so it is generally used for gold prospecting or relic hunting in highly mineralized ground. Pinpointing is done with the heel or toe of the coil.
Coil Size:
There are many different sizes of coils available and each one may fine tune your hunting but only if you get the correct size. Larger coils go deeper than smaller coils but only on larger targets. When using a large coil, you may lose sensitivity to small targets. A large coil is also more susceptible to masking. Masking happens in the discriminate mode when a good target and junk target are both under the coil at the same time. If the targets are close enough together, the bad target will be discriminated out, and at the same time, the detector will not be able to pick up the good target. Masking is very common in junky playgrounds and in-and-around old house sites. Smaller coils will concentrate the signal and make the detector more sensitive to the little targets. Unfortunately, smaller coils tend to lose depth when compared to their larger cousins. Being that these coils don‘t have as wide a search pattern, they are also less likely to mask targets in trashy hunting situations.
