Thread: Multi Freq in Iron

    Multi Freq in Iron

    I saw a YouTuber say single frequency is better than simultaneous multi in iron. Is this true?

    I never run multi-frequency but when I do it's one frequency at a time. - Donnie B. (Deus I user)

    it would depend on the type of iron and machine Drew , yes in most cases with average bits and pieces of wrought iron in the soil a machine's processor can more quickly sift through this matrix information with only one frequency but its harmonics are limited and depending on just what that frequency is (very high , low or mid) you may not see significant discrimination through all types of metals or even size of the targets . Although Beach sand which contains iron (black sand) and because of the presence of a lot of salt one frequency machines struggle at best to find anything especially at depth. Two frequency machines also can produce more harmonics ( sort of like sub frequencies) that may help to locate small or metals along the broad range of detection. I also think your "youTuber " maybe right when it came to machines 5 to 15 years ago but not so much with today's higher end machine technology , the processors today are incredibly faster than a few years ago. So I'm not sure I gave you any real answer

    Very interesting. I'm waiting on the Deus II to come out with the regular headphones. Also need to find a dealer that may give me a discount. I'm not in a hurry.

    Just my 2 cent piece here, as I'm not so sure about your youtuber. I know when I switched from my single frequency to the CTX3030 it was a game changer in every way. Sure, the single can be somewhat dialed in for conditions, and on some machines like my Minelab frequencies can be changed by swapping a coil which can help finding certain ranges of metal better. But the multi sure puts it to shame. I couldn't count how many times I found masked items because I would see the multiple signals on the screen or hear those slightly hidden peeps, and the fact that I can tune the machine for heavily mineralized soil also makes the difference between good finds or going home disappointed.
    For example, I have a lot of black sand on the beaches I usually hunt and the single would just freak out and give me no signals even on surface targets I could plainly see, while the CTX can easily find small targets like earring backings at a foot or more. This wasn't as effective on saltwater beaches, but that could have been just my inexperience too-although in the surf a salty wave breaking under the coil would probably make any VLF machine lose it's composure. In cases like that it was time to break out the PI machines.
    Minelab: CTX 3030, GPX 4800, X-Terra 705. Whites TDI SL.
