Hi,

 I recently inherited a Garrett ADS Deepseeker. I have never used a metal detector, and after going through the user manual, it seems that this unit is not working properly. When I turn it on, I can adjust the "Tuning" to achieve a faint tone. When I place the coil over a metallic object nothing happens. The unit came with 2 different coils and both behave the same way.  Doing some searching on the internet for schematics for this unit I came across one for a similar unit. The schematic showed two coils, a Tx and a Rx coil.
The coils I have, have a few feet of cable then have a 4 pin connector on the end of the cable that plugs into the detector.When I check the resistance of these pins I measure approx 5 ohms between  only 2 of the pins,  Should I measure 2 different coils in this connector?
  Any other ideas on what might be wrong with the unit would be greatly appreciated.

Thanks

There should be two coils in each coil head so it looks as if both suffer the same issue. You can call Garrett on Monday for advice. They're very helpful over the phone.

I removed connector body on both coils to verify problem was not in the connector. Both have the same problem:

pin 1  connected to ground of connector
pin 2 -- pin 3  5 ohms
pin 4 no connection

With ohmmeter connected to pins 1 and 4,  tried moving cable where it enters coil, to see if the problem was there. Did not get any continuity
It seems that the problem is inside the coil. Has anyone tried opening a coil up to repair it?

The grounded pin is wrong for sure. Somebody must have tried to modify the coil. Those machines are all two coil VLF/TR machines.

Since you don't know the history of the machine, you might consider scrapping it or sending it to Garrett for a checkup. At any rate, call them today on their toll free line.1-800-527-4011 (USA/Canada only)

Here is how they are wired.       This info is from Garrett.

Here are the pinouts for both the 4 pin connector and 5 pin connector.

 The Shield wire is on Pin 1
 Black wire is on Pin 2
 Red wire is on Pin 3
 White wire is on Pin 4

Did you check for a reading between pin 4 and 3?

I called Garrett. They were not really that helpful. They indicated that I would not be able to measure the coils in the search coil unless it was connected to the unit. Doesn't sound logical to me if there are two coils of wire in the search coil, I should be able to measure continuity with it disconnected from the unit. The coils is wired as follows:

The Shield wire is on Pin 1, also connected to non-existent center pin(which connects to cable backshell)
 Black wire is on Pin 2
 Red wire is on Pin 3
 White wire is on Pin 4

I measure approx 5 ohms between pins 2 and 3
No other connections anywhere. Sure seems like bad coil to me. Seems strange thought that both would fail.  Can you measure the 5 ohms and 20 ohms are your coils?

I too find it hard that you have two coils bad.  The center pin on the 5 pin set up is the Shield to coil and  center point of coils.   Do you have the 5 or 4 pin?   Pin  seems to be a added ground to all? Or only on the 4 pin connector.  I dougt the coil end is your problem in any case.  The shied is the only thing that has ever failed on me on that end.  In the older coils they use Window Screen Wire as a Shield  and the connections came loose.  You can take the coil open by zippo knife along the seam of the coil but your not going to be able to do much.  There filled with Foam and Epoxy.   A real mess in there.   I don't think your problem is the coils.

The connector mounted on the cable from the coil only has 4 pins(center pin not there). I am not sure if this is a 4 pin or a 5 pin.
If I remove the cover from the connector it has the following wires inside:
The Shield wire is on Pin 1(also connects to missing center contact which connects to connector backshell)
 Black wire is on Pin 2
 Red wire is on Pin 3
 White wire is on Pin 4

only measure 5 ohms between pins 2 and 3. No other connections?

Try all connections 2,3     3,4     I don't have one to try  ..

Just measured my Garrett S3 Coil (4 pin) 15Khz  got the following.

Pin 2,3   12 ohmes

Pins 1,4   43 ohms.   No other connections except 4 to shield. same as pin 1.

You have to wait for the reading to settle down.  There is a Cap in the Coil.

Did you open the box to see is the problem is not on the connector inside?
