I used the:
Equinox 800 w/ 6" coil Park 2, Sensitivity 23, 2 tone, Iron Bias f2 0, Recovery 4
Xp Orx w/ 9" hf coil, 4 tone, Sensitivity 96, recovery 2
Gold Kruzer 4x7.5 coil, Deep mode, Sensitivity 80
I wanted to see how well these detectors did in no emi area at a low mineral sandy beach with a 0.89 gram 14k gold ring buried at a measured 9". I was very impressed with the results.
The Equinox 800 w/ 6" coil and the XP Opx w/ 9" hf coil hit all the way around with the coil lifted 3"-4".
The Gold Kruzer w/ 4x7.5 coil hit it one way w/ coil raised 2"-3". The other was a weak signal harder to get. I was happy with that. I didn't bring the 5x9.5 coil. I'm sure it would have done better.
Over all I was happy with the results. The Equinox 800 w/ 6" coil did really good. Equal with the Xp Orx w/ 9" hf coil. The Xp Orx hit the ring very well at 31 khz and 54 khz.

I'm going to use Deep mode, sensitivity 80-90 and disc 0.
By using disc 0 the Gold Kruzer is able to get an air test on my 10k white gold earring at about 3" both ways. I don't understand why increasing disc to 22, which disc out nails, will not hit the gold earring very well. The earring id bounces around 20-45. It seems like it should hit it ok with disc raised. Even disc at 19 doesn't hit good. As the disc is lowed it's only gets slightly better. 0 disc hits best. Deep mode hits it better than all metal. The Deep mode hits it hard and all metal is very quiet hit in air test, maybe 1.5-2". Micro mode has to be almost touching to hit.
So I'm going out with disc at 0 and see how I do. My thinking is I won't miss much gold.
Didn't do very well this last summer. No gold. Got 2 silver earrings with the Equinox 800 and 6" coil for the summer. Northern Michigan is tough detecting.
Received my AF28 coil in and put it on my kruzer.
I started out in 3 tone because that is what I would have normally ran anyway but, that was before I tried it out.
No more 3 tone for me.
I have the Fe tone set at 2 and sensitivity set to 85 and in the standard 15khz freq for starters.
Separation is very good with this machine with set up of the settings with this coil. I am very satisfied with it. It has about the same ability to separate as the smaller 9.5x5 DD coil. Very impressed.
But moving on with the 11 inch coil, I discovered a quirk when running the coil over a the 7 inch dime and 11 inch nickel while in 3 tone. The machine did not want to hit on the deeper coins. It would try to null out. I cranked the sensitivity up to about 93 and although it would respond to something being in the hole, the ID for both coins were off. I was starting to get disappointed.
I then swapped freq to 5 and then to 19 as well and was getting similar results.
So I tried it in 2 tone and whammo....it nailed the deeper coins in all 3 frequencies with the sensitivity turned way down as well. Then I tried 4 tone and the same thing happened. The machine responded very well with the deep coins too.
Very happy now.
But I can see if someone got this coil and tried to test it just in 3 tones how someone could get discouraged with the set up.
I have read a lot about 3 tone with the multi kruzer and leaving the sensitivity down below 90 because it you are supposed to be able to get more target information and signal analysis while the Kruzer is in 3 tone.
I found that advice to be total bull$hix.
anyways, if you want more depth with a kruzer with the 11 inch coil with multi tones your gonna have to run in 2 tone or 4 tone because 3 tone is not going to cut it.

I want to build my own large coil (just exactly as GOLD KRUZER GK40 COIL) as I can’t get a new one in my area for certain reasons. Can anyone here help providing:
1- how many turns in RX & TX?
2- size of wire used in both dd coils?
3- the way the wires and shields wires are connected at the bottom and in the connector pins?
(the last point confused me, couldnt figure out how they connected those wire!!)
appreciate your guide and help.
I started out the day on a high note by detecting an old farm that I found a Rosie and a merc on a previous outing. First good signals were some 22 casings. I then got into some 1970's pennies and hit a bunch of wheaties, The oldest was a 1919 pretty good I thought. Next up was a kids silver plate bracelet. Was hoping for better but it was not to be. After about 45 min. of trash I stumbled on an odd 1 3/4'' copper piece. This is very unique and I have no clue what it was. Last but not least was a 1943 p nickle, my first of this date. I thought it was an odd silver but seeing the delamination on the surface, my hopes were dashed.This nickel was at the 10'' mark.
Now for the bad part !!!!
On my way back home I decided to try and get permission for another old farmstead. This property is having a new house built on it and I figured why not. There were some drywall guy's there who did not speak english, so I decided to look at the old barn before I departed. The first sign you are in trouble is when a black cat tears ass out of the barn and almost hits you. I should have realized I was headed for problems. Anyhow I decided to leave, Jumped in my big truck, pulled foward and into a 3 foot ditch I failed to see. After stacking about a ton of stone under my passenger tire I got out. But It will cost me a new bumper $350, Brackets $52, and possibly a new fender $400 + paint. I'm not sure my finds will cover my stupidity!!!
My wifes thoughts were, Glad it wasn't me. You would have bitched for days about my bad driving. Sometime's dumb catches up with all of us.
Damn Black Cat !!!!!!
