Frank in Oz,

Yes indeed I purchased this coil from Phil. I have not yet used it to find eluval placer in western Nevada-- the acid test as far as I'm concerned--- however, I'm pleased to say as a chestmount I have been able to use it in local urban areas as a coin machine. I found a penny in my front yard and last Sat on a club hunt at Fairmont Park in Riverside where I used it to find 20 nickles, 7 dimes and 2 quarters. The coins were on the surface in the grass.

I will say upfront I do not recommend using the Infinium and Australian coil as a "full time" coin machine to hunt any land areas such as a park or schoolground, but to mention this setup runs quiet and smooth and I was able to pick out and pinpoint coins around possible electrial contamination.

I have not tried the Ausi coil out as far as sensitivity to smaller gold. However, thre week before last I gave it a good run---a big circle--- around several club claims in the Randsburg/El Paso Range area in the Mojave desert of Cal.

I did this just to "feel it out." I now "think" after my limited experience the Ausi coil can be banged around without falsing. It can be swung faster than the standard 10x14. That it seems to have good depth.

However, the "acid" test will be in several areas that I know of in both central and western Nevada.

Up front I do not sell detectors, I am not an employee of any manufacturer and I buy all of the machines I use.

I am myopic. I have a degree in geological engineering and tried to specialize in the "big-five" replacement deposits (copper, lead, zinc, silver, gold) of eastern Nevada and the epithermal gold-silver-mercury areas mostly associated with acidic volcanics in western Nevada.

As a public school teacher (1967-1992) up to about 20 years ago I did weekend, summer vacation, small-scale consulting work for various mining companies. Mostly underground in old mines.

In 1981, "deep underground" in an silver old mine in the Basin Range Province of California, last worked in the 1870's. I pushed a small penknife in to a stull. the wood looked good by eyeball, but the small penknife blade went into it like "butter." At this time I decided at my age and physical condition that I know longer had any business in mining and then started to specialize in soil engineering

Beginning in my childhood I was around both hardrock and placer operations. I have been involved in drywashing back in the late 1930's at Osceola, Nevada. Later in the late 1940's at west Comstock (Jumbo) near Carson City. Then in the 1950's-60's around Lovelock and Winnemucca. From the 1960's up to the early 1980's I drywashed in the Mojave desert areas of So. Cal, some of Az and also back in Nevada.

However, as detectors improved I got more involved in nuggetshooting. It the early 1980's it was possible to find placer over a weekend in many areas such as Dome Rock, Az; and also around Randsburg, CA. Since 1981, as a hobby and certainly not as a pro, I have found a "small amount" of residual-eluvial gold using 24-different makes and models of VLF-type to PI-type detectors.

You nention an"Update" for the Infinium? Interesting.
