Default All Metal vs Coin Mode

Fairly new at this and need enlightenment. If a detector has both audio and visual indicators, and if it is supposed to go deeper in all metal mode, why use the coin/jewelry settings? Wouldn't it make sense to use all metal and choose your digs using the visual or audio indications?

Depends how much your brain can accurately process,a signal is normally acquired through audio and confirmed visually. I hunt one type of conductor at a time,if I’m coin hunting. That way I can pay attention to one specific small range of tones and TIDs. Listening and trying to interpret everything can be mind numbing.
True depth is achieved by coil size. Conditions can and will affect the end outcome.

AM (All Metal) will get deeper, but, what they don't tell you is everything else becomes basically useless. No Visual ID or Tone ID that you can depend on. You just pretty much have a beep-N-dig situation. If it makes a noise, you dig and hope its something besides junk.

Very few places have I ever found AM useful. If a site is super clean, is there such a thing?, or a tot lot. Maybe the beaches I wouldn't know because we have none.

This has not been my experience with my detector. The differences in how the signal sounds and vdi actually still works pretty well for me the majority of the time. and I hunt cellar holes mostly.

Understood Tpmetal, but I have yet to find a detector that hits a 12" piece of metal and can accurately tell you if its iron, copper or silver by sound or VDI.

You can do both, there's a number of detectors that run an AM and a discrimination channel at the same time, best of both worlds.

I was referring to motion a/m- which, even on my Ace 250 has tone and visual ID.

Most detectors don't actually have all metal. They run in discriminate all metal as they call it. The only all metal on most detectors is in pinpoint.

Detectors using mixed mode, use discriminate motion and pinpoint non-motion at the same time, that makes them detect most everything in the ground.

Yes and no, the last 2 mixed mode detectors i've had, the all metal side was motion.
But they did have some form of filtering in all metal, and there was a big difference in sensitivity to small items between them.

Pretty sure the Ace 250 doesn't have an all metal mode.
It has no threshold, no manual ground balance, and only creates 3 digital sounds. (I had the Ace 350 and loved it for a first detector.)

You can set it so it doesn't mute any tones, but I think it only has a disc circuit.

I HAVE one! It is MOTION a/m. It gives a low grunt on nails, paper clips, etc. No, it doesn't have a threshold based, wavering, true a/m mode because of a preset g/b. So if you're hell bent on finding gold flakes-or iron flakes, for that matter-no it doesn't do that. But yeah- you will find iron and tiny gold that falls in that range. I enjoy that mode because it's smoother than a pure, threshold based a/m, although in iron laden trashy areas the low grunts are annoying. FWIW, Relics mode is awesome-just enough disc to rid small iron- but not enough for larger nails- which give low grunt.

That's the smart way to do it, as some fine gold gives off the iron grunt. Have also found nice pocket knives. Also more likely to hit good targets near iron trash. After a while, sizing , sound, and other characteristics will become familiar. It's just that some hunters find the continuous sounds annoying and would rather cherry pick. The "lucky" hunters use a/m.

This is what all metal and a discrimination sounds like at the same time.
You can hear the all metal first as it approaches the coin, then the ping of the disc channel, then the all metal again as the coin leaves the coils field.
When the target is deeper, you might just get an all metal report, without the disc report. You then have to rely on the how it sounds, does it feel smooth and round etc, or with this particular machine, switch it to deep mode to confirm ID.

Lol you opened a can of worms! Your gonna get multiple answers because “all metal” can be different on different detectors. On my old fisher F4 there was a “all metal” setting. Basically if there was any sort of metal you got a tone. All metals made the same tone and there was no visual ID in this mode.
What type of detector or detectors are you talking about. If you give everyone one or a couple examples we can address the MD’s you are specifically asking about.

Agreed coin chase. For me AM/All Metal has no target ID or tone ID it is pure unprocessed AM which is why it goes deeper. Not a lot of filtering damping the signal. If you get target ID it isn't true AM. In true AM everything will sound the same.
