Advice on Used Excalibur's

Check coil and headphone wires for cracks,
 

How much are they asking if you don't mind. ?
 

Something else to check when you check the coil and headphones, look at the cabling, if it is starting to look like it has a white chalky dust on it the cable insulation is starting to break down and will start cracking.
 

Put the earphones on, turn it on and move it and the headphone cord around to make sure the sound does not cut out.
 

find out the last time it was serviced, like the O-rings and the battery.

TH,

If one found this, would cleaning and covering with silicone grease, or something like that, extend the life of the cabling?

Patcat recommended I do that for my own equipment period, and there's no sign of any trouble right now. Water hunting is up for the season up here now, so I still need to attend to that, and will. I know I've seen this recommendation many times here.

Thanks!

Thx for reply...
What would that tell me, do they require scheduled maintenance? Or is there a way to tell if whatever date they tell me is accurate?
Or Would I want to avoid one that's been serviced or not serviced? Thx again

Look at the battery pod's terminals. There should be no corrosion and the black plastic gasket should be in place.
Make sure you get the charger and the adapter for charging.
Check coil for cracks and there is a coil cover included.
Make sure all controls rotate smoothly and that the PinPoint control's stop is working properly, I.e. only about a 30 degree rotation.
Look for any visual water marks inside the tubes.
Look for signs of overly tightened cable ties used to hold the coil wire to the shaft. Use of electrical tape is better than cable ties.
Audio from right and left side of headphones.
Ask about battery life...should be over 12 hours of detecting time. If less than 10, you'll be in for a new battery soon.
And of course look for any physical damage to the entire detector.
 

Or you could just get a CZ-21 and forget about all the Excal's vulnerabilities. Not trying to be a smart alec, but a used Excal - at a time when ML non-warranty repairs are taking several months to process - might not be a good bet.
 

beach hunting requires a GOOD Minelab.......just saying :occasion14:

Keep looking till you find a used water machine that's a year or less old. Bought a c21 that was 4 months old for half price on eBay.

I'm not sure, I'm getting ready to send my blue 1000 in to be fixed for this very problem. I'll let you know what they charge me. Good luck!

New stock headphones are $150 plus $75 installation labor, Gray Ghost Amphibians are $150 and $112.50 labor installation. If o-rings are bad add $8.00 in parts (17 o-rings) and $37.50 more in labor if done at same time. If knobs are hard to turn o-rings have dried out and need replacing.

Just remembered ... twas gonna post this eons ago... for those here on T-net...
But my A.D.D. must have taken over ...

this is in regards to "maintenance" per your inquiry...

Here is what seems to be a little known (amongst detectorists) "tool" in my bag of tricks... and I love it.

Sold at Home Depot and elsewhere.

PS >... Spray on ... let sit over night... take fuzzy towel the next day and clean.

O-rings... very small droplet on each.

I would not use that on o-rings, it has petroleum solvent in it, not good for the o-rings at all... Each pot switch on a Excal has 3 o-rings unless you take your excal apart you can only get to the top o-ring, you can't get to the one below it or the one on the inside. I recommend Mcnett silicone spray. (Thanks To OBN) Used on scuba gear.

only 4 small screws to check the condition of the speakers, these work but 1 has a higher volume,water is getting in and slowly corroding the speaker.

Looks for cracks on the pod in the knob areas. Check to ensure it has the rubber to the battery pod.... and check that pod for severe cracks on the cap. Put it IN water..... listen to see if the threshold raises or you get crackling in the phones. Turn each knob to ensure they stop...... especially the threshold and sensitivity. Looks for separation on the bottom of the coil.
