1st test run of the 6 inch HF DD coil :thumbup:

[khouse]

Two words. BUY IT.
I hunted two pebbled tot lots with the coil. Of course it picked up the coins. But what was surprising was the little bitty tiny targets it could hit at depth. I'm sure this thing will get me a nugget if I ever get to where nuggets are! Also I wanted to see just how close I could get to the equipment supports. This is where I find some good stuff. I lowered the sens to #1 and with a slow sweep I could get the coil to within 1.5 inches from the supports. I found no targets at this lot but did perform a test. I put a copper under the pebbles at about 1.5 inches from the post. The coil picked it up off the front end. I'm happy. Also I could accurately pinpoint by Xing the target and finding the target dead center. Or I could use the pull back method and the target was always under the nose of the coil about 3/4 inch. It pinpoints either way very good.

Minelab's small (yet powerful) 6" DD High Frequency Coil

It is a pretty good coil, isn't it?! I had a dealer once tell me it was fantastic compared to the 5x10 Elliptical (which he was not exactly impressed with). But the Elliptical has a much better side coverage which exceeds the actual surface area of the coil itself.... yet the 6" is more sensitive. Especially to small targets. The ONLY problem with the 6" is that it needs to be directly over the target to detect it. And I mean dead-center. This might be a hindrance on the gold field if you're after 'larger-than tiny' targets because the little 6" is actually going to ignore targets that are not directly under the exact center of the coil. You could scan a modest sized nugget with it and it's likely that nothing will happen unless you hit it with the coil's "sweet spot". Go near the same nugget with the Elliptical and it will sound off even before the coil edge overlaps the target. Use the same elliptical on a small nugget and forget about it. You probably won't know it's there.

The 6" DD HF can detect a 0.02g micro-nugget in air or on the ground (not so much under the ground). This is almost too tiny to be bothered with but in a creek, those little nuggets often accumulate in cracks etc. and can amount to more than just a few golden grains. The signal response will be louder too if there's a bit of gold in a crevice. Both coils are probably needed by anyone wanting to Prospect with their X-70. I think Coin Shooters would find both useful although they have their own specialized needs based on where they hunt. You seem to have discovered the very clear Dead-Center Targeting ability of the 6" coil with pinpointing. It works well at this too!

Do any other owners use their 6" HF DD and prefer it over their Elliptical?

I never used my 6" HF for gold, but it is a killer coil in iron infested ground like around a cellar hole. My partner and I have been hitting this one small cellar (not inside, just around it) time and time again. On the first trip with the stock coil, up came about 30 buttons. He went back several more times and thought he "cleaned the clock". I went back with the little scorcher and it was like hunting the site for the first time, I was amazed. Over 60 buttons and 3-4 Colonial coppers came from this little spot. We plan on sifting the dirt in the hole this coming season...after hunting around it yet again. The 6" coil does have a small footprint but that is the charm. It sees very little and you have to swing it slow and be patient. Ron
