Pinpointing question - newbie sounding

Where does the coil pinpoint on this machine? I'm going to make the switch from tesoro where it pinpoints nice and centre of the coil. I've watched what seems like hours of video and am trying to understand why it appears some struggle with this. The following video is great right up to the end and then there is this massive hole dug for a coin. I don't get that. I actually felt ill when I saw that. And I'm sorry for using this specific vid but I'm really interested to make sure this is an exception and pinpointing is actually quite easy. Thanks.

If you listen to the tone increase in volume and pitch, (about the 4:10 - 4:15 mark in the video you posted) you'll note that the "spot" on the ground is quite narrow, compared to the size of the hole that he ended up with.


The CTX 3030 offers you a choice as to whether you prefer "Normal" Pinpoint or Sizing Pinpoint.
With Normal Pinpoint, the first sweep over the target will generate a wide audio response. With each successive sweep, the width of the audio response will be automatically reduced until there is only a very narrow response at the center of the search coil. Make a mental note of the position, pass the coil over the target at right angles (90 degrees) repeatedly until only a narrow response is heard. "X" marks the spot.

With Sizing Pinpoint, the width of the audio response does not change. Activating the Sizing Pinpoint as you near the target allows you to manually control the width of the target response. Some prefer Sizing Pinpoint as it allows us to get a good idea as to the size and shape of a target.

Another method that many find success with, using DD coils, is to slowly X over the target while moving the coil closer to you. As the target tone fades away, the target will be under the front "lip" of the coil.

He could have done a neater job but it looks like he is in a wide open place where some people will take more liberty with their plugs. Also, if one suspects a very nice target, a larger hole than necessary often will be dug to reduce the chance of damaging the target, it does look like he made a three sided plug which will heal real nice though.

The CTX will pinpoint right on the money in the center of the coil and you can use a screwdriver down to 3-4 inches if you want to. The DD coil is a bit different if you are used to a concentric coil but with a little practice as Digger outlined, you can recover deep targets easily with a 3 or 4 inch plug.
 
I went back and watched the video and he sure did not spend much time pinpointing, he could have done MUCH better.

If you want a good laugh from this video, turn on the closed caption and watch how the CTX tones are interpreted into words....... some of it is REALLY funny.
 
Great tips digger
 
The CTX does a great job pinpointing the target. I feel it is improved over the Etrac. It takes a short learning curve converting from a concentric coil to a double D. You will find it accurate and quick.
