Detech 15″ Ultimate Spiral DD Searchcoil... Anyone Use It

[Calmark]

I would definitely recommend wearing a harness and bungy when running this coil.  It sounds like you are prepared in your thinking. 

I found 3 nuggets in one red-colored extremely mineralized patch of dirt at good depth with this coil. My dad went over it previously with his GPX5000 and 14x9 Nugget Stalker coil and me with my SDC.  The 15DD Detech got some deeper nuggets at 8 inches we'd missed.

Later, my brother and I pulled some other nuggets out of this spot with his GPZ7000 and my GPX6000, though it was when the ground was bone dry and the least noisy.

In nearby areas that were less hot, I tried the sharp timing for a short while and it also ran quite smoothly like sensitive extra and normal timings.  I do think in super hot soil, this coil can likely beat out a mono coil where the added ground noise can drown out nugget signals.  The trade-off is weight and a mono coil out-performing it in milder soil. 

I have not tried this coil in really wet soil, but I suspect it would handle the added ground noise well, even running in the more powerful timings on the GPX.  Use those powerful timings like normal or sensitive extra in bad soil and make this coil shine.

Are you planning on using it for gold or relics/treasure?

Just one thing to consider if your using it for treasure, most treasure is small coin or up size, so sensitive coils can be a detriment as can be higher gain settings.

I found the best combo was gb off or sharp if it was on in some places where the soil required it. And I would lower my gain so that I did not constantly pick up small surface junk targets.

The opposite is required if you are going to use it for gold, high gain and I'd definitely run the spiral over the traditional bundle wound.

Here in Australia I ran it over extremely mineralised ground for gold but the monoloop coils and timings still out performed except in extreme conditions.

I'm using it for nuggets. Got a patch I've been working g with the stock 11 inch coil...been getting nuts to 2 dmt, down to about 13-14  inches. Want to hit that next level, and cover more ground. It's a big, wide open area.

I am using it for relics and it is very good at discriminating a large amount of iron, much better than the commanders, now yes, it is very heavy.  I had to buy the pro swing harness to swing it

Hey Guys,

  We have been a long time Detech dealer and this is one of the more popular coils Nuggetshooter's use for higher mineralization, discrimination (if your detector has it) and more coverage per swing.  As you can tell, they are also very popular for the coin/relic/beach guys for good discrimination and depth.

Hey Rob! I actually left you a message on the office phone the other day. Was gonna try your cell, but been crazy busy with work. I will get hold of you in few days, pick your brain, and buy a coil. Thanks for the input. Ray

Hey Deathray,

  Yes, I was on vacation for about 4 days, but back at the "Salt Mine" now.  Give me a call when you get a chance and we can talk more.  I have boxes of Coiltek GPX 6000 coils to now ship out.
