Hi All!
I have not posted in a while but wanted to be more active again. Since I got a CTX over two years ago, I have longed for a coil that was bigger than the tiny 6in and smaller than the stock. I was excited when I heard that Minelab had licensed Coiltek to make an elliptical coil for the CTX. This coil seemed to fit the bill but I wanted to thoroughly evaluate the CT before getting too comfortable with it on the machine. Most seem to assume the coiltek will be primarily useful in trashy areas of areas with a lot of iron. Since I already have a trash coil in the 6in, I was hoping that the coiltek could do more...
I had the week off this last week so I decided I would hunt with the new CT all week to develop some impressions. I also did some unscientific air testing for those who are interested. As you can see from the air test videos that the coiltek is not bad on depth. In my unscientific testing it demonstrated 80-90% of the depth of the stock coil.
When I went out hunting, I used my typical A+3 setting. I found the coil was stable and immune to bumps. The TIDs were in line with what I typically get on other CTX coils. As you would expect, pinpointing was accurate and very easy. The coil is less susceptible to iron falsing but it is not immune. You would be advised to go slower with this coil than with the stock coil. Separation is excellent! It is at least as good as the 6in maybe better! The depth readings where very good with one caveat. The surprise was that as targets are deeper than 6in the readings tend to underestimate the depth! For example a target at 7in might really be a 8in. The depths on deeper targets were occasionally underestimated but never seem to be overestimated. The 17in coil overestimates depths and this drove me crazy for awhile since I dont always dig shallow targets. On three hunts, I found about 25 wheat pennies and some neat tokens but no silver with the new coil. On the fourth hunt, I was busily rescuing wheats, and got another 12.43 hit at 6in. I assumed another wheat...
Here are some pics of the coil and some comparisons with other CTX coils (6in first and then stock)
