I've read from several people and forums that using the "bobbing" method on my CZ6 is superior to the other way of grounding. Now how do you know it is?? Why? How can you compare them?

I use the bobbing method because I found it easy to set up the detector that way. I have not spent the time to compare results between the two methods. The manual that I loaded from the fisher web site for the CZ5 says the bobbing method may cause fewer falses in bad ground so ... bobbing is what I do.

I would think that to compare you would want to work over some mineralized ground, put some targets in the ground deep enough so that you start to get an iffy signal and then try the two ground balance methods and see if you see the target better with one setting versus the other. You could also set the ground with the pin point method and then try bobbing in autotune to see if the ground balance is different and then see how it responds to targets.

I just know that i get get less falsing, i can run the CZ3-d at a higher sensitivity without it becoming unstable and i have found hundreds of silver coins and or cool artifacts with this method. lets say i used the push button method i would have found a lot of the same stuff but how about that 10in deep 1851 silver 3 cent piece that bounced between iron and foil or the 1853 half dime 12in deep that gave me a solid relic tone on the 3d . [I DON'T THINK SO] I think for general use the push button method is fine but if you want to run it to the best of it's capability's you have to use the bobbing method HH. Tim

I think using the bobbing method, you can fine tune the GB better. Also, you can use the pin point method first to get an idea where the GB is set, and then bob to fine tune it.

I have not done any comparisons using the 2, but I was at a beach yesterday where there were tons of hot rocks and the 6a was hitting on them ever so slightly. I got a hot rock, ground balanced to the rock using the bobbing method, and the machine ran smooth. Did not sound off or false on the hot rocks after that since I ground balanced it out.

Is there any video or can someone can tell me how to "bob" my detector? I tried but I don't know if I am doing it right. I own a 3D and want it to run the best. Its in the shop, so when I get it back I can use it more effectively. Thanks.
