Iron Volume/depth

[CPT_GhostLight]

It's all personal preference. Iron volume does not affect depth, but can affect your perception of deep targets. I usually run my Iron Volume at the stock settings (3), but in heavily man-made iron infested sites, I usually have to drop that to 2 or 1 to keep the constant bombardment of iron sounds from causing ear fatigue and to allow non-ferrous targets to pop through better.

I usually bring it to 5 especially with square tones when I don't use headphones, 
with headphones I have to lower it .... 
with pwm tones the volume of the iron is higher you can hear it better
