Question about switching coils on Sovereign XS

[rick201m]

Newer guy to MD here and need some help.

When changing out the standard 8" Coinsearch coil to a 12" Sunray S-12 ultra coil, can one only change the plug at the coil or do you need to use the wire with the specific coil and re-wrap it on the shaft?

Also, can one take out the connection on the back of a Sunray DTI 2? It looked like it wasn't a pin connection type plug and just the wire only.

Thanks much,
Rick in CO

I'm not sure I understand your question but each coil comes with it's cord attached and to switch coils, all you do is disconect the coil cable at the box then connect the coil cable of what ever coil your going to use to the control box. also you might want to buy extra "lower rods" so you dont have to keep re-winding the cable everytime you change coils.
hope this helps,

The connection don't come off at the coil as it is just a strain relief for the cable. The cable connect to the back of the meter and is where you take it off at to switch the coil. Remember once you switch the coils the calibration will be off too and have to be re calibrated to 179-180 with the control on back of the meter on a new dime or quarter.
Now as far as the meter that should have a connection where the coil connect too that is the female, then there should be a wire with the male part that goes to the control box also coming out of the meter. This cable may look like it comes off of the meter, but it too is a stain relief and does not come off.

Hi rick201m, and welcome.

What looks like a connector on the coil, is actually called a "gland" and clamps down on the cable to provide a water tight seal. This is not a connector! The cable is permanently attached to the coil at the factory so don't try to loosen the nut. So the answer to your first question is yes, you have to unwind the cable each time you remove the coil.
The good news is, you will soon settle down to your favorite coil, and changing coils will not be an issue. I have an 8" Coinsearch, a 12" WOT, and a 10" Tornado, and I have been hunting with the 10" for the last year and a half.
Can't answer your second question (I don't own a Sunray meter), but I assume that the SunRay has only one connector, and it is on the end of the cable that goes to the control unit.

Good Luck and Good Hunting.

Problem is mistaking the strain reliefs for connectors. Leave them alone.

Also I don't consider winding extra cable around the lower rod to be a good idea. Makes it more nose heavy, and gets a lot of cable close to the transmit field. Don't like the idea of getting more unwanted signal pickup in the cable than necessary.

I find I run only one or 2 turns of the cable on the lower shaft and wrap the rest right above the clamp to hold the lower shaft into the upper shaft on my 10 inch Tornado coil. On my Coinsearch I have shorten the cable to make it easier to change.

That's about the same way I do it too Rick.

The one that really is a problem to wind on is the T-10 cord. Very springy.

...but all my coil cables are still just as the came from the factory. Too lazy to shorten them, I guess.

One concern for newbies, if you don't use the meter, you don't want to make the cables so short that you can't hip mount the control unit, (just in case some day you might want to do that).

Shortening the coil cable to reduce EMI pick-up makes sense to me on an intuitive level, but I'm not so sure that the coil engineers haven't already optimized the coil length (and other factors) for the best performance. Especially in reducing ringing and parasitic oscillations, which can be a bear to eliminate. I imagine that the Pulse Induction folks have to take a really close look at coil cable length on their detectors.

Just a few thoughts.
