Well after an interesting day of detecting I thought I would revisit this thread as to why some detectors are so expensive.
Now speaking of minelabs anyway, since as far as I know they are the only ones that have a very unique feature, and as I'm finding out even on my old explorer, that feature is nothing short of incredible, and the feature I'm talking about is: iron mask. Which I think on e-tracs and newer its called quick mask.
Now I think to fully appreciate this feature, one would have to have been doing this hobby for a very long time, as since anybody that has been doing this a long time, knows a lot about how things under our coils affect what we dig.
We old schools are very familiar with the masking effect and how it works intimately, and for anybody new or old school, the masking effect is what occurs when you are detecting and say you get a iffy signal, that sounds or looks good, but mostly looks like junk, more so if you are running a good amount of discrimination, example you are looking for high conductive targets, say silver coins, well say there is a merc dime at 7 inches, but above it at say 4 inches is a rusty nail or bottle cap, if on most detectors you are discing out said nails odds are your detector will not even register the coin since the signal from the nail is stronger, therefore masking out the coin, and you end up missing the coin.
Now with the explorer and etracs having this feature of iron mask, this allows the detector to basically see through that nail at 4 inches and pick up the dime below, as I said the old schools would appreciate this more so since we know how much we hate the masking effect of iron near good targets. How exactly iron mask feature works, I don't really know, but I've figured enough that it reads the ferrous content of iron.
The ability to see through the bad to the good, in my opinion definitely makes these detectors worth what they cost, I don't know what my explorer cost when it was new, but I'm gonna assume it was way more than the 500 bucks I paid for it considering all the stuff that came with it, I would gladly pay the 1500 bucks for the etrac if I had the money, for this feature alone makes it worth it, for old stomping grounds are almost like virgin sites again just because of this feature..
OK then, night hunt time.
