Pinpointing with a concentric coil

[hat_man]

Hello everyone,
I am thinking about getting a 5.75" concentric coil for my Cibola and was wondering how you decide where your target is when you can't see through the coil. I know it's probably a silly question, but I am rather new at this. The spoked coil that came with the Cibola is easy because I can see through it and has never let me down. It's always right in the center hole. I have permission to hunt on some old farm property and it is so overgrown that I can't hardly swing the stock coil through the grass. Someone suggested the smaller coil and it makes perfect sense. Is the target off the toe or heel or is it still in the center? Thanks for the help.

hat_man,

The concentric 5.75 coil does pinpoint in the center. After you perhaps detune and center up, stop the coil movement and look at the dead center of the coil. (You may find it easier if you mark the center with a brightly colored dot or piece of tape.) move the coil quickly out of the way while staring at the dot and after a dozen or so times you should be able to pinpoint within 3/4 to 1" or so. My method is to then carefully insert an ice pick into the ground where you think the target is. That way you can look away to get a digging tool,set your detector in a safe place, or whatever.
I find that a closed coil works better than a spoked coil for relic hunting. The spoked coil tends to get caught on stubble and sticks etc. where the closed double D just floats over and through the obstacles. The 5.75 will also go places a larger coil will not. ( Some depth is lost with the smaller coil,especially on larger objects.) Remember depth means nothing if you can't get the larger coil where you want to hunt. If you have any other questions you can PM me if you like. Joe

Joe told how to pinpoint. When you have the target pinpointed in the center of the coil, stare at the center and move the coil away and the spot is right where you are staring. It only takes a couple minutes practice on finding coins under a sheet of newspaper and you have the skill for life. Note that a coin on edge may give a wrong position reading.
