YouTube has provided a platform for people to post videos on virtually anything and they get the views once they are posted. There are some excellent videos out there but then there are others that are "dead-on" when it comes to say a specific type of hunting in specific conditions but when applied to an area 1,000 or even 100 miles away, the results can be disappointing at best.
I have met a number of "setting of the day" hunters who continually download settings from the forums or YouTube and go out the next day to try them only to switch to something else the following day. Without a solid understanding of what the change does and why it is being made, frustration is often the end result.
As far as ground conditions in the US versus Europe and the UK, I can attest to the fact that they are vastly different due to the history of use, the mineral composition and other factors. Take the infamous ground surrounding Culpepper, VA . . . . drive 50 miles in any direction and the ground is totally different and far easier to hunt in. The same holds true in the Atlanta, GA area . . . red clay that renders many detectors useless at more than an inch or two . . . . if you are familiar with that area, two words sum up the ground -
Brushy Mountain
The beauty of the Deus is that you can make adjustments on the fly and see immediate results. In some areas I use Tracking while others I run Manual and in fact drive it negative to press the depth. Does it get "chatty"? Yes, but there is a reason why I do what I do and if it becomes unusable, I can simply make a change with the understanding of what the change is and what the expected result will be.
I have had several people call and ask about GB, Ground Notch and running positive or negative in Manual . . . . after walking them through the difference and having them go out and see the difference, they see how to adjust the GB for their area and for the type of targets they are looking for . . . . unfortunately there is no "magic setting" that works for everyone and for all types of targets.
Gary is extremely knowledgeable about a wide range of detectors and in his areas, has mastered the Deus . . . . but having hunted there, I can say that the conditions are different than what we face here which calls for different settings.
