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 just got my 11" coil in and it seemed super light. Comparing it to the stock 7x11 that weighs 471g w cover and cable the 11" coil only weighs 492g with cover and cable.
Depth wise the 11" seems almost the same or at least air test I can't really tell.
Did they reduce the amount of copper in the 11"? Tech specs say it should weight 540g.
If anyone has an 11" for their Kruzer or have an Amphibio stock 11 can they post the weight of it? Thinking my coil is out of spec.
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 !!!!!!
After another long hot week and some things that are weighing heavy on my heart. I decided to hunt a little woodlot and creek to take my mind off the grind of life. I walked about 1000 yds down the creek with little luck until I found a odd item that looks like an umbrella handle. A short distance later I retrieved a very very small tea cup (cool). After striking out on the water, I thought that I might have better luck on terrafirma. Shotgun cases woo hoo!!! I then decided to hunt near a giant of an oak tree, every bit of 40'' through. Hoping for something good, I got a good deep hit. At around 11'' out popped a very large musket ball that measures .690 to .695. Thinking from a british brown bess. Spent another hour farting around and tripped up on a 97 number that kept bouncing down to the high 70's. Normally this would be coal, but the tone did not have the crackle that coal usually has. Woo Hoo out popped a 45 mercury dime. My second 45 in a very short time. Turns out that there were very small fragments of coal around the merc. The dime is cool, but I love Rev. War musket balls!!!! I ended my day with a 22 casing and a 22 bullet. Another good day with the MK!!! Time to have a beer and cool off!!!
