The benefit of AM mode on the VAQ

[skyboy09]

Heard a lot of praise on using All Metal mode in certain situations or because it gives your more depth but never tried using it on the Vaquero because of the annoying threshold sound. Can someone teach me on the benefits and in which situations it comes in handy? One thing I was told is that's it good in conditions of highly mineralized soil where the detector beeps at every sweep when there's nothing there, but when I tried it the threshold sound never stayed constant. It changed in pitch just like it changes when you're pinpointing something, so that was the end of hunting in AM. But i don't want to give up, hehe

About the only time I hunt in AM is when I'm scouting a virgin site. Looking for clues for a old house location, or areas where people congregated. I'll stay in AM for a bit if the site is clean of trash. Most times though I switch into Disc.

A ll Metal mode is just that.............all and any metal. The threshold sound should be tuned to a slight whisper of a tone. When you are scanning, even deep metal will alter the threshold slighly, not enough to activate the discriminated tone, but enough to tell you that something entered the field to alter the tone. This is why headphones are such a plus. It's not that the detector is any deeper, it's just that you can hear the smallest of change in AM by listening to the threshold.

If you GB properly, set the threshold to a slight hum and get a constant change in threshold (with no metal), chances are your ground is mineralized heavy in different areas, or your gain may be too high (sens). AM has it's place. I would use it if I wanted to dig everything it found, like around an old house. It's also great for relics. But if your searching for coins and rings, Cisc is the still deep on the V and will keep your trash to treasure ratio better.

Well said Dan. Many say they search in All Metal and switch to Disc when they get a target to help ID it by the setting of their Disc. Trouble with this is AM is deeper and switching to Disc might lose the target just because it isn't as deep a field.
