Hello people since I've upgraded my detector to the equinox in the last 12 months I've been doing beaches. But with the coronavirus not many people are visiting the beach anymore. So I decided to go to a couple of my local parks. Anyway my equinox beeping everywhere on anything and everything does that mean the ground is just full of iron clad junk,? I turned the sensitivity down to 16 I took all metal mode off I tried pak 1 and park 2. Was driving me nuts in the end I just gave up went home. Any tips thanks

The most important detail is whether it was beeping when you weren't moving the coil.
If it only beeped a lot when you moved it, and there are no highly unusual ground mineral issues or ground balance settings, then maybe you're just used to fairly clean hunting spots. Welcome to the world of trashy park dirt! I often hunt areas and entire yards where I hear a dozen beeps with every swing.
If it was beeping even when you weren't moving the coil, then that's electro-magnetic interference.
After you noise cancel, there are two different approaches to dealing with EMI. 1. Cover up the effects of it. 2. Eliminate it. The solution is usually a combination of these things depending on the property and hunting goals.
This is about the Equinox, but some general ideas are universal.
Silence the effects of EMI:
-Notch out most of it. This is OK if it's mostly very low or very high (as mentioned by oaktree)
-increase iron bias. More quick high tones get reported as iron (as mentioned by oaktree)
-Reduce recovery speed. Fewer quick hits get reported.
In all cases above, THE DETECTOR STILL "HEARS" THE EMI AND HAS TO PROCESS IT. All you've done is apply a few tricks so YOU don't hear it. Processing power is still being dedicated to the EMI and it's competing with legitimate signals.
Reduce EMI: The goal is to unburden the machine from processing EMI in the first place.
-Move away from the source (obvious)
-Try a different day or time of day
-Eliminate the source (Turn off the invisible fence!)
-Reduce detector sensitivity
-Try different single frequency modes
-Smaller coil size
Let's say I'm in a park and stuck in EMI. I'm on vacation, determined to hunt, and can't go anywhere else or come back. I'm fine not digging anything super deep, and I still want the benefits of multi frequency. What to do? Lower my sensitivity to the high teens, run a higher iron bias, notch out -9 to -3 where the EMI seems to be hitting the hardest. Maybe even switch to the smaller coil. If that works, it fits my hunting goals.
Or, let's say I'm in a fairly clean yard and I found some deep coins last time I hunted. The permission runs out today and the homeowners are gone and left the invisible fence turned on. I want to use the big coil and prioritize sensitivity. Going through the single frequency modes I discover that the EMI I'm hearing in multi frequency is actually contained entirely to the 5 kHz range and completely gone in all other modes. I can work with that! I'll hunt in 10 kHz--good for deep silver anyway--using the big coil and sensitivity up high. Nothing notched out so I can hear the deep iron tones along with the deep high tones.
In both solutions the priority was to think about hunting goals, and as much as possible not just cover up the EMI but rather eliminate it. Or some combination of the two.
Hopefully that gives you some options and ideas.
