I played a little with recovery speed adjustment on beach targets. I am looking for a way to have targets sound longer than they do - like smooth mode on the CTX. I tend to run high gain where you start to hear the random noise signals. Problem is that target sounds are same pitches and duration - sometimes same amplitude sometimes louder. I’m wondering if I’m setting up the audio wrong - I never have messed with the headset gain. Would increasing it and backing off on detector volume give more dynamic range? How do you guys adjust recovery speed, sensitivity, and volume levels?

Recovery speed adjustment

Increasing Recovery Speed shortens the duration of the target.
For detecting in a trashy environment, increase Recovery Speed.
For detecting in fields with little trash, I run Recovery Speed down to 1.

Great idea on the tone spread.
Your 'Theory' works if you run FE off: 50 Tone: Recovery 1
However, doing this 'lengthens' Ferrous Signals dramatically (some coins too, particularly those of bi-metal content e.g. 1 Euro, 2 Euro - these can have a 90% Non Ferrous with a 10% Ferrous end signal portion) and while annoying, can be telling in it's ID abilities because iron & bottle caps can sound WIDER with a 'Bell-tone-like' sound while bi-metal coins will sound a ferrous signature at the end of the coil swing.

What Des said lol. Reducing recover does lengthen tone....... Also the higher the pitch the louder the volume and size of the target seems. Example.......15 is a lower tone which kind of shortens the target and isnt nearly as loud as 25. I run full volume on everything above 0..... everything below it is set to 4.
I'm on a short vacation on the CA central coast with the EQ800. Setting the recovery to 1 is a no go on these beaches. Seems to pick up the salt or iron in the sand and make a tone on left sweeps only. Weird. Dropping the sensitivity had no effect. Had to go back to a 6 setting. Has anyone else experienced this? So far this has been a very strange detector compared to the others I have. It does have depth but it seems I bought it right when conditions are the worst I remember.

I figured Recovery speed of 1 would be fine for beach hunting since targets are spread out. However, pinpointing was a bear because the target gave a large signal. Couldnt tell what side of the hole it was on. Also got that tone on the end of the swing which also drove me nuts.
Was advised to raise the recovery speed and that cleared up all the problems. With 800 you have more choices. You'll have to experiment and see what works best. I only have the 600 and 3 works just great for me.

Did you ground balance the reason I ask is I was hunting and was getting 5 high chirps a swing just little ones so I noise cancel same thing lowered the sensitivity just made them quieter they were still there .
I had factory default of 0 for ground balance I did a auto ground balance my #s went to 73 started swinging again and it was as quiet as a church mouse had to throw down some change to see if it was working .
So I would say it's a ground balance issue in my case the noise I heard was ground noise sensitivity just made it louder or quieter . sube

I've been using mine on the Santa Monica beaches and I'm still in the stock beach 1 mode. Only adjustments have been to increase my volume to the max and increase my sensitivity to 23. Works great on the wet and dry sand. Once I get the coil under some water I get a little bit of chatter and I I'll lower the sensitivity to 21. I didn't think the EQ would do as well as my CTX but I'm getting just as deep targets. I got a small broken gold chain (3 pieces found close together) a couple weeks back that locked dead on 1 in the wet sand. The bigger part of the chain was 4 grams and the two small pieces were about a gram each. I don't think my CTX will going to the beach any time soon from now on. 
Randy, do you get targets that ID and sound good but are too abrupt - like you aren’t getting the coil over them? In all metal you hear the iron associated with them. Just wondering if it is safe to ignore these types of targets. A couple I did dig were iron scraps.
How obvious are coin audio IDs for you? I can easily miss them except maybe the corroded zincs.
In the central coast beaches I had to go to Beach 2 to shut down the chatter from the waves. Didnt find anything in the water though.

The manual says to auto ground balance if the ground becomes too cattery. I find that the machine runs better when you auto ground balance from time to time as you are hunting. It's a fast and deep machine...I would NOT run the machine recovery speed down to 1. Most of the time I hunt no lower then 5 recovery speed and still pull coins 7-8 inches and deeper regularly.

Hi Strick,
Do you run quiet with perhaps threshold or do you tolerate the random blips and bleeps to get perhaps a bit more depth? Do coins really stand out or are they just a curious tone that you surmise you should dig? I have dug zinc pennies and bits of foil over a foot deep that sounded like 2" deep. Detection is so abrupt and lacking of dynamics I can become complacent and miss targets. I suppose if I ran quieter, targets would be more obvious but they haven't developed unique character in my brain yet and I'm getting frustrated. I haven't messed with much of anything like zone volume or iron related settings. Most I've read when hunting beaches you set Beach1 and go. For the water (knee deep) it seems Beach2 is better but I haven't found many targets with it. Curious if you just turned yours on and hit the beach or if you had a more methodical approach to it that helped you learn the machine better.

It is a interesting topic this one as every one has a different perspective on it, but I really do not think that there is one magic setting for them deep targets as I do change settings for the different beaches around here because of the black sands that are layered through the white beach sand. I run on 24 for sensitivity 7 for recovery speed most of the time, when it gets chatty I slow down the swing. If it starts to really get chatty then I will change sensitivity down till I just get the occasional chatty sig. As for depth I'm happy as found 20c pieces under a rock down 17" . Have pulled 1c and 2c (copper coin) regularly 14" . Most of the deep targets will give no numbers but I mainly listen for the different tones and if I'm convinced, a few scapes of the top soil and recheck , Its amazing one or two inches of the top can make the different wether to dig or not, but normally dig because I'm curious to see what the target is to what tone I'm hearing . The cook uses beach 1 as set from the box and she a slow swing person and picks up a lot more targets deeper than me, the saint Christopher traveler charm with sterling silver chain was dug up at 26", I had missed it but the cook was doing the follow up behind me and got it, she had no numbers but gave a good mid tone, yep I got bagged out on that one for missing it 
. In Australia we don't have the real history of old stuff that has been buried over time, most of the coins and artifacts are with in the 1" to 5" range so it reasonable easy for the detector to see, but some of the mineralized dirt dose play havoc with the EQ800, even had a chat to minelab about it at a field day( thanks to Jason) we got it working better than I had it set up for the real heavy mineralized soil, but every now and then it still go's berserk.

I don't seem to be having that issue. In the wet sand I've been getting some bobby pins that come is at 9-10 that sound off but aren't loud and clear. In the wet sand coins come in loud and clear, they ID pretty well too. I've had deep coins that don't read right until I get them out but I knew by the sound the target wasn't iron. I've had some deep nickels that read in the single digits until I get them out. When I first got the EQ I think I was moving too fast with it because I heard you could swing it faster than the CTX or E-Trac. When I slowed back down those deeper targets started coming in more. The stock Beach 1 program has worked great for me at SM. Last week I hit SM at low tide but the conditions were terrible, I bet I didn't even find a bucks work of change in the wet sand. Had to go to the dry sand just so I could dig some targets. The EQ has been fun to use and its a killer on nickels, don't think I've ever dug 21 nickels before and I got that many on one of my SM hunts a few weeks back (you would think one of them could have been a ring 
). Some of these nickels were close to holes where others had been there before me. Stick with the EQ, slow down, keep that coil flat on the sand and listen for those deep targets that at first barely sound off but should stop you dead in your tracks to recheck. HH
