Finally got a Superfly for my Multi Kruzer. It weighs just .01 lbs more than the stock 7x11. Overall it is less chattery and I can kick the gain up much more. Depth wise on a silver dime it at same gain settings it will go between 2"-3" deeper with steadier numbers. Target separation seems to be about the same and in the field I gave it a go for about an hour or so and it was really nice to swing. Though I only found a bit of clad I plan on giving this one some serious hours.
Not sure if it is a worthy upgrade for anyone with an Amphibio but if you have one of the Kruzers I highly recommend it.

What is wrong with the Gold Kruzer?
Why doesn't NEL or CORS or Magic or Detech make any coils for the Gold Kruzer?
They make full lineups of coils of for the Gold Racer, but not a one for the Gold Kruzer.
You can't say its because of the water proof connector, as they make coils for the Kruzer and Anfibio.
You can't say its because of the frequency as they make coils for the Gold Racer and the Gold Kruzer is basically a waterproof Gold Racer.
So what gives? Why do the aftermarket coil mfg's treat the Gold Kruzer like an ugly step-child?
So I have the Green headphones and have them currently paired to the Multi Kruzer but it seem that if I pair the pin pointer to the same headphones then the headphones won't be paired to the detector? Either or and not both? If that is the case it is kind of a bummer but not that big a deal. Audio on it isn't super loud with the waterproof cover on.

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.
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.
