Need help with dfx

[countrycody16]

I just bought a whites dfx spectrum e series and I can't seem to get hardly any depth I've got the eclipse 950 coil My grandad has the same detector with an older coil and has the same custom programs and I've founds coins up to 9 inches with it. But I can't seem to get mine to get past 4 inches any suggestions?

First if you bought it new it might just be there are no coins deeper where you hunt. Do a reset of the DFX and test it out on coins on the surface. Using custom programs don't always increase depth as much as you think. Stick to Coins and Jewelry mode till you learn it better. Depending on how its set up you could tweak Gain a bit.

I have had a dfx for years and over those years I have found ways to get depth out of them . Here are a couple of pointers . First turn your detector on and put It on relic . The reason I do this is every time you discriminate something you loose depth and you will not believe how many targets I passed over because they was by iron and it bleeped them out using discriminate ( coin and jewelry mode) next turn your pre amp gain up to a steady level and you a.c sensitivity up to a level your machine does not go nuts probably around 68-70 . This should help alot . It takes alot of time to learn the dfx I am still learning after years of using.

Filter settings are VERY important on the DFX. For me, that was the "ah-ha!" moment for learning the DFX. Basically, you want the lowest filter that will give you smooth quiet operation at your normal sweep speed. Find a deep coin-sized target that is right at the deepest edge of the detection limit, then start trying the filters one-by-one, until you find the one that works the best for your soil. You'll see it obvious when you have the correct filter selected. You'll be like "wow, that is so much better" when you get the right filter selected. For me, it is usually 4 and sometimes 3. If you are getting only 4 inches, you may be waaay off. So once you get a good filter setting, you may have to go find another deeper target to further fine tune your filters on. Find the best filter first, then you can mess with the AC/DC sensitivity and preamp gain. And a Sweep Speed setting of 5 is a good all-purpose safe setting for good performance in most areas. I think the stock program is a little high, maybe a 10 if I remember correctly.

But get the right filter selected first and foremost. The DFX is a fine detector. It sometimes gets a bad rap from people that don't understand how to use its settings. But once you figure out how to use those additional settings, you'll never want to be without them.

To add to this Jeff Foster's book Digging Deeper with the DFX on page 102 (beginning @ paragraph #5) he has beta on how to determine if higher Ground Filter and Sweep Speed settings are a good choice. Great book.

Once you have found a hard hitting non-ferrous signal, leave it in the ground and experiment with different GF & SS settings, while checking the Signagraph for improvements.

Depends on the frequency I would suspect 3klhz is deeper for coins and silver and 15klhz is deeper for gold. Of corse preamp gain ac factor in depth.
