I kind of wish the audio and iron audio on the Apex was like the AT Pro. AT Pro Iron audio is vco and very handy to tell size of iron. That along with the wide iron range gamut still makes it a good relic machine despite what people think.

I tend to keep iron audio on 1 on the apex and regular volume on 8 so I have a heads up on whats below. I also disc just above 40 when coin/relic hunting but if in a park I'll have iron audio off and disc much lower. Coin Jewelry here I am shallow hunting in parks so no real need to hear the iron at all.

Some the places I hunt have negative hot rocks and those areas I like the Tejon and can check with pin point or will use my Gold Racer or Multi Kruzer in Gen Mode so I can hear the bouncy signals (reverse roll). Machines that don't have an all metal the negative hot rocks can sound like a valid target and you can easily dig holes around the rock.

Thanks,
Ken
