Recently I wrote on the Minelab Treasure Talk blog about my first experience with the CTX06 six inch coil. I was more then impressed with it’s capabilities when used in a very trashy old swimming site that I have hunted many times with a number of machines.
last week I had the opportunity to return to the same site to detect some more with this small coil. I decided to continue from where I had left off out in the water and almost straight away had a nice signal amongst the null signals from iron and lower tones of pieces of lead. Coin number one for the morning was a penny, dated 1958.
Not one of my oldest finds, but I’m always happy to find predecimal coins. The next coin was only a few meters away and this time was a silver sixpence from 1942. Carrying on I had the some bits of brass and a few large pieces of lead which sound to good to ignore. One target that sounded pretty good, if not a little rough turned out to be two pennies in one hole. Another penny had me digging nearly about 300mm down to recover it. So there is no doubt as to the sensitivity of the small coil.
The tally for the morning was seven pennies, one sixpence and one very worn threepence. I’m certain looking forward to getting back to this site and I have a number of others now that I’m keen to go over with the six inch coil.
One thing I have learned from using this small coil is that while a big coil is great for covering a lot of ground, if you want to get in amongst the trashy sites and pick out the good stuff you need to slow down and take your time!
