Craig, I have used a bunch of Coinstrikes and also had an Excel that I put about two hundred hours on. First, the Excel is a great coin detector with very respectable depth. Does above average job in junk. I just saw one for sale that was used less than two hours with a Sunray probe for 220.00 from a respected member. What a deal as the probe alone is about 180.00. The Coinstrike is a winner in my book, but the most important adjustment is the threshold. It will lock on a coin and if the vdi numbers stay in a three digit range, it is a coin. It is the most sensitive detector I have ever used when walking around a target, checking it from all angles. I find that if you don't do this, you will dig junk. It seems to get a perfect tone and a good number with every sweep, but if you don't check it from a 90 degree angle, it is not always a coin. If the tone and numbers stay relatively consistant from different angles, start digging. Yesterday I dug a way deep 1912 wheat penny(9plus inches) The signal was faint, but consistant and the numbers stayed in the 22 to 25 range. Awesome and as deep as any detector made today. I also dug five junk targets at this depth, but they have characteristics that I knew they were junk. They all had a consistant tone from all angles, but the numbers changed to the mid teens when I checked from 90 degrees. I guess what I am saying is this detector will lock on a coin even at depths. I don't have problems with old bottle caps because they will be all over the board with their numbers even with good tones. You have to trust the detector and pass on these targets if all factors are not consistant. Also, the C$ is great in trash even with the 8 inch coil. A small coil is even better. I dig the least amount of deep rusty iron with the C$ which is a good thing if you are strictly a coin hunter. I turned the iron disc off yesterday and I was amazed at how much iron was in the ground. One thing I don't like about the Coinstrike and CZ's is the weight of the 8 inch coil. It is not too heavy, but the detector is slightly bottom heavy. I bought a Sunray probe and did not like the balance of the detector so I took it off. If anyone is interested, I will sell it for what I paid for it(85.00 shipped). This probe will work on the ID Edge also. Good luck and don't be shy about asking for help as there a bunch of experienced Coinstrike users here. R.L.
