MUST SEE VIDEO FOR EQUINOX USERS!

If you use the Equinox you need to see this video.....

don't have the 800, have the 600 but that has to be something for people to really think about.

I noticed that at the beach on corroded quarters, but the tone and and numbers were solid vs. a similar effect with corroded crown caps, but the non-ferrous tone is usually distorted or flutey and/or the numbers jump. So even though I was getting a ferrous tone with the quarter, something about the tone quality told me to keep digging and I pulled a quarter. Another thing at the beach was that I was running into a number of multi-denominational coin spills (quarters, dimes, nickels, and pennies). Those gave numbers all over the place but solid high tones from the high conductors though they were "interrupted" by the mid-conductor tones of the nickel or other denominations and included iron grunts too. So to the inexperienced hunter that could be mistaken for a flutey bottle cap. So you understanding the tones and non-ferrous "reverse" ferrous falsing is an important thing to learn about the Equinox. I will pay more attention to this on my next hunt. Thanks, Scott.

Something to remember, and dig some of those, thank you.

This happens on most machines. The CZ-21 for example will give you a nice mid tone on a gold ring, but when you move off to the edge of the coil you will get an iron tone.

The reason is simple. Metal detectors simply measure the change of inductance of the coil which is caused when additional metal is introduced into it's electromagnetic field. It's that simple. Metal detectors are not radio transmitters contrary to popular belief.

That inductance shift is not only dependent upon the metal, but where that metal is and how it is positioned in the magnetic field. If it's right on the edge, or ON edge, you can get weird readings, which is why deep targets often sound like iron.

Because this machine uses a DD coil, the width of the field is much narrower than the depth.

Deep wheats and IHP's will do this VERY often too. I hunted with Tnetter Sgoss while he was home and we dug numerous deep wheats that were doing this. 3 IHP'S also. If my signal doesn't "walk" and it sounds a little deeper upon pinpointing it gets dug up. Especially at an old site.

As mentioned before many clad quarters will also do this too. Even some silver on edge. I try to use the signal sound, duration, pinpoint and consistency together as my final dig decision.

Double post....

If I suspect iron I'll get my shovel as deep as possible and give a little pry. Breaking the halo works often for me lately. Signal goes from an iron false to junk really quick. Lol.

I pretty much dig anything with a repeatable high tone in two directions regardless of whether or not there is an iron grunt at the edges.

hi I'm new to this site but just watched the vid ,maybe its the small amount of tin in the bronze that's effecting the reading.

First of all, welcome aboard.

Regarding the tin content in brass targets, as an alloy rather than discrete dissimilar metal parts (like a brass buckle with an iron tongue), a metal detector cannot discern individual constituent metals as it is looking at bulk alloy conductivity and magnetic field distortion (due to target shape and orientation with respect to the detector coil). Now a target comprised of discrete constituent parts of dissimilar metals like the brass buckle and iron tongue or a bottle cap with corrosion or multiple dissimilar metal targets in the same hole (coin spill of different denominations or coins and nails) will give mixed ferrous and non-ferrous combined tones for that reason. The combined ferrous, non-ferrous response for a non-ferrous target is best explained by flgliderpilot's inductance discussion above. A metal detector does not inherently know what type of metal it is passing it's coil over, it just infers it based on the conductivity measured through the inductance shift and magnetic field shape distortion detected by the coil. Also note that several metals and metal alloys have similar conductivities (such as gold, nickel, and aluminum) which why it is hard for a metal detector to discern the difference between a gold ring, US nickel, and an aluminum pull tab.

hi I'm new to this site...

I noticed this was your very first post - so, Welcome Aboard GoldenHiker! You didn't list your state (or country) in your profile. So, you might consider jumping over to Sub-Forums: Select Your Area.... and selecting location information (i.e., clubs, hunts, finds, legends, maps, etc.) directly related to your state (or country). You might also consider adding your state (or country) to your displayed profile (SETTINGS -> EDIT PROFILE) so if you ask a question, etc. - people may have more success helping you (your location may help, etc.)...
