Iron Bias Question

[Iron Buzz]

When might I want to make changes to Iron Bias setting? What sort of conditions & hunting warrant it?

I may have just found the answer to my question in this thread: http://www.treasurenet.com/forums/equinox/582884-one-thing-i-m-not-liking-about-800-a.html

I hunted every day since Feb with my 600. I'm in quiet fields, Nail infested cellars, trashy parks, etc, and I've settled on zero iron bias. I can't really speak to the whys and what-fors but I can say I hardly ever dig twist tops or cans. I get almost no falsings. I don't crank the sens though...about 19 in trash, up to 21 in the open fields. I never had a minelab before February, coming from the T2. So maybe, people with minelabs for years can crank the sens...I can't...and I'm still digging dimes at 8in and two coppers each at a foot. My record was 11in with my T2.

I have mine set to zero. In my air tests I was passing up gold rings next to iron if it was set higher. The higher setting increases the chances that a target will be labeled as iron. In an area where you don't want to miss non ferrous targets, set it lower.

Same here - it is a filter that supposedly helps with iron falsing. I don't much care about that since I can interrogate the target in all metal mode and listen for the accompanying iron tone. IB will keep you from picking up masked non-ferrous amongst thick iron if you invoke it. Other than moderate levels of discrimination, I avoid any other notches and filters and let my brain figure it out. IB = 0 for me.

Run mine at 1 but might lower it to 0. I wouldn't run it higher than 1 for fear of missing masked targets. Cuttin the sens down to 18 to 20 helps in the iron most from what ive found.

I too run mine at 0 or 1. Some tests I ran convinced me that any higher and you will miss any non ferrous target that is close to iron.

Would you go with that in Park 1 as well? kind of makes sense to do so.

I run iron bias in 0 in every mode.

 

[Calabash Digger]

Park 2 is where im at.

Many good and valid points here. On our trashy beaches, I run 0 iron bias in all metal and let the tones indicate what might be under my coil. When hunting relics, same....relics made of ferrous material are important to the museum I support.

Just the view from my foxhole...
