Omega 8000 question??

[tj3445]

Can some of the more experienced O8K users enlighten me on how best to use the iron signal meter in the top right corner?? Any info will be much appreciated.

tj3445, I am assuming you are asking about the Fe3O4 bargraph which measures ground mineralization. Scroll back thru the forum and check out posts by Bubbadirect on 06-07 and Monte on 04-26 on this subject. Txquest

The Fe[sub]3[/sub]0[sub]4[/sub] meter is mainly there to alert the user when the ground mineralization is extreme so that you can adjust the detector and your hunt style to suit conditions. Ground readings are only accurate when bobbing the coil over target free ground. Bars showing up while detecting are mostly caused by the coil going over metal targets. Except when doing the ground grab procedure I seldom glance at the Fe bar graph since the most I have ever seen in my area is 2 bars and that was one rare occassion over a small area of ground.

Knowing the iron mineralization of the ground is important because high mineralization can cause depth loss and non-ferrous targets to read down in the iron range. Since the discrimination mode(s) on the Omega are silent search, meaning no background threshold hum, without the bar graph meter as an alert most would never know when they are dealing with high mineralization.
