Incredible Depth- 
The frequency range of 1.5 kHz to 100 kHz is the REAL horsepower behind the Explorer ll's world famous target depth... here's WHY: 

The lower the frequency, 1.5 kHz for example, the deeper the signal travels. And, the higher the frequency, 100 kHz for example, the more sensitive the signal is to smaller objects closer to the surface.

Simple Physics right??- Read on... 

Treasure Targets in the ground respond differently to different frequencies--making signals stronger or weaker depending on HOW much a frequency "excites" the target.  If you only have a limited frequency range like other brands, you're limiting yourself to what you may find. You could be walking over VALUABLE targets you don't even know are there!

(Can you trust the frequency range of your current detector?) 

The Explorer II combines the best of both worlds- Frequency RANGE and DEPTH! When you're hunting with an Explorer II, you can be sure you have the most powerful treasure hunting detector in the world. You'll have the technological edge other brands only dream of.

POWERFULLY ACCURATE- 
Multiple frequencies operating simultaneously sends and receives much more information to the Explorer II than a standard 1 or 2 frequency VLF detector. This information is then processed by the Explorer II's NEW 2nd Generation software to provide the world's most accurate discrimination .   That means you don't have to waste time digging trash! The Explorer ll's microprocessor eliminates the bad effects on depth "ground conditions" may cause.   

SIMPLE yet incredibly VERSATILE- Beginners will appreciate the Explorer II's "turn on and go" simplicity. Just turn it on, set your threshold, press noise cancel, and you’re ready to hunt in settings optimized for virtually any condition. Advanced users will love the power to customize countless programs to suit YOUR treasure hunting needs.
