Like all things new, it takes time for results to feed back into the general community. Overall, there have been some very good reports from people using the GPZ 19 coil. Early adopters who have been tough enough to brave the heat of summer here in Australia have been reaping the rewards, as well as fast-tracking their experience levels for when the weather cools off, come Easter time…
For some time now I have been keen to get my hands on one of Minelab’s CTX 06 six-inch coils for my CTX 3030. Recently, I finally bought one and couldn’t wait to get out and try it on some trashy sites that I have had success on in the past.
Any potential treasure hunter investing in a Minelab metal detector has seen the words “Treasure through technology” written on the box. Recently seeing an empty Minelab metal detector on a shelf in my garage, brought a big smile to my face as I thought back to the first time I ever saw those words printed on the box.
Finding old stuff with a metal detector should be easy, right? Just go to old places? If we were to break it down to the bare bones basics, yes, that’s what you need to do. However, finding old places that contain old things is way harder than it looks on paper. Sure, you can drive around town and look for old houses but do you know what “old houses” look like? Would you be able to tell the difference between a remodeled house built in 1880 versus a house that was built in 2015?
Many years ago while researching for the TV show Hoard Hunters (History Channel), we looked at a site near Whaddon Buckinghamshire where a hoard had been found in the 19th-century. This hoard of Roman coins were unearthed while the field was being excavated for land drainage. A pot was hit and coins spilled everywhere, so there was a good chance a few had been missed and that would make a great TV show to watch... if only we could find the spot.
I was again honored to be invited back to Oak Island in Nova Scotia Canada to take part in Season four of the History channel show “The Curse Of Oak Island.” The team called me excited about having more areas to search on the Island, I packed my trusty CTX 3030 and travelled up to Canada hoping to deliver on my promise of doing my famous gold dance.
In the ever growing market of accessory items available for your detector, the one product that has experienced somewhat of a revival is the humble search coil. There is a myriad of coils available on the market for your gold detector these days, which has lead to endless questions on various forums, blogs and social media groups begging the question: “Which coil should I buy?” So my aim for this article is to inform you about coils in general, what makes them different, what various types of coils are good at and why having a wide selection of coils isn’t a bad idea.
When I first purchased the Minelab CTX 3030 it changed my detecting forever. My confidence grew, my finds rate multiplied and the depth I was reaching…well let’s just say Australia was not too far away from the bottom of some of my dig holes. This instant change in fortune was also while I was using the standard 11 inch coil, a superb coil especially for general searching and the more trashy areas, such as recreational parks, beaches and Victorian dump sites.
The CTX 3030 was the first detector Minelab made that used wireless audio and it does a nice job of things, so nice that at times it felt difficult going back to my GPX 5000 when I wanted to look for gold.
Then came the GPZ 7000 with no speaker built into the unit so operators had to either plug headphones in direct via the audio socket above the battery pack or use the supplied WM 12 wireless Audio Module. The WM 12 is a pretty neat system on the GPZ and allows for operators to pair up two WM12s for either dual speaker use or to provide an audio source for a partner walking along with you whilst detecting. I use this feature a lot during training sessions and find it very useful.
I recently received an email inquiry regarding the purchase of native silver specimens. While I have none to sell, I thought this might be a good topic to examine for Treasure Talk. Few metal detector operators have ever hunted for native metallic silver, but it does exist. Most newly mined silver is extracted from silver bearing minerals that will not sound off on a detector, but natural metallic silver will certainly trigger a metal detector if the pieces are large enough. While native silver is not an uncommon mineral in silver deposits, it often occurs as small irregular flakes, wires and masses disseminated through the vein, and the pieces are often so small as to be invisible to a metal detector and nearly invisible to the eye without the help of magnification.
