Minelab Excalibur Top O-ring inspection / silicon lube / replacement

[@hardmanners]

Thanks a lot for another helpfull Video! Never checked before and I'll right do it tomorrow. Guess you saved my machine. Thank you!

[@oldbeechnut]

I learned the hard way, I fixed a excal sword but never check the o rings, then when I took it in the water to test it was fine for about 5 minutes then it started going crazy, luckly it was pool water. From that point on I check all....and then I realized about 1 out 4 need o rings, specially any over 5 years old..Good Luck...most of the time it is the top o rings only....

[@pcphunter]

Thanks for the informative video!
Could you please give the size of O-rings in millimeters fot Excalibur 2?

[@PinkPowerAllyTreasureHunter]

I'm hoping the next Minelab machine release it will be a wicked new underwater machine (with better nobs lol) Thanks Joe for sharing your amazing skills!!

[@doesanyonecareatall]

I can not figure out which o ring for the end caps. Help I am on mcmaster web site but 70 buna 3 x32 makes no sense. HELP

[@gettinrings]

cool vid !!!!!
I was wanting to know how to do this... I have only had my excal2 for about 8 months now... but I want to make sure it stays in top shape.
keep up the great work !!!!!!!!

[@akerhun]

This tutorial worth gold Joe!

[@joebelin5383]

Gonna put my excal 2 in the salty drink of Myrtle beach soon. What are the steps of cleaning it afterwards? And the PM of it. Thanks. Btw. Ur the king of the SEA!!👊🏼. Love ur videos

[@oldbeechnut]

It gets a little boring as I am putting the o rings in but I want all to know that it is easy but may take a few minutes for each, you just have to keep working them in, just remember the more silicon grease you put in the harder it is to get them in. That's why I suggest maybe just coating them, then they go in very easy and still do the job...Thanks Guys, Good Luck to all this coming hunting season...

[@tasteegold7772]

+Joe Beechnut excellent video and advice as usual..to add to your method i just applied a tiny bit of silicone to the outer part of the pots o ring's so no sand sticks to it. also when i'm using the detector and adjusting the settings turn the knobs super slow so the potentiometers dont get worn out quicker (also saves wear and tear on the knobs)and to top it off i dunk the entire unit in a large bucket of fresh water after every use just to make sure the under part of the knobs get rinsed as well AND wipe the entire unit cables and all down with uv protectant spray......basically i baby the thing lol

Always interesting Joe---Down in OBX now---not many targets---trying Corolla again tomorrow--Take Care and thanks for sharing

Hi Joe, great your video, I even got an Excalibur the very first model with the horseshoe disc, could you tell me how to remove the knobs? because I would like to change the gaskets and I'm afraid of breaking them. Thanks in advance.

[@oldbeechnut]

You will need to put masking tape up one side then the other to save the decal. Take a flat blade screw driver and work around each knob slowly prying them up and off.

[@jbapt38]

@@oldbeechnut ok I understood the manipulation, thank you very much.

[@WildDigger]

Great video Joe thanks for the information.

[@1digitalmemories]

Joe should the plug connection to the re-charge battery pods from Excalibur 2 have a 3mm gap when plugged in?

[@veroniqueschelcher311]

[@divedetectiontechnologies663]

And what about other smaller rings, that installed inside on the shaft? Are they need replacement?

[@oldbeechnut]

99.9% of the time they are not affected by the outside environment since they are totally sealed. And the only way they can be changed is if you break the excalibur down fully, than the shaft can be pushed from the outside into the inside of the control Pod and recovered. Than replacing them you will need to make a special tool to install the shafts that are in the middle of the Pod. I drilled out a tooth brush end (as a holder) so the middle shafts can be set back in place.

[@divedetectiontechnologies663]

[@GoldSniper-ox7rk]

I just bought a used one of these, cheap, £350. Can anyone tell me are they good for inland rocky ground searching for raw silver and gold as well as the beach. Or any other information that might be usefull.

[@oldbeechnut]

I tried mine on land hunting for relics and coins. I would not recommend the xcal for anything other than in the water.

Mr. Oldebeechnut thanks for sharing. I want to replace mine and was wondering if you could sell me some. Also I'm interested in modifying my Excal's original headphones with the Grey Ghost type.

YB, unfortunately my supplies are exhausted. If you check back in Nov I should have stocked backup by then. If needed just email I can send you the link to order them....

Hello Joe my friend owns an excalibur 1 (horseshoe) and he bought an Excalibur 2 disc for change but the wires are not the same color and number (6 for Exc 1 and 5 for Exc 2). Could you help us? Thank you in advance.

And on the Excalibur 2 disc the wires are: brown, gray, black, yellow, so there is one less wire than on the horseshoe disc.

@@Kalambagood где же такие искать?

[@c.h.u.d]

I'd think putting sillycone grease on em would attract abrasive sand

[@oldbeechnut]

Since the knobs set flat on the o-ring and small tube not much is exposed. So if you apply a lot and it squeezes out ..the area around will collect sand if you hunt rough water where the sand gets stirred up. The o-rings are covered so they are fine. Several years I hunted this type of water, where the surf is pounding the shore, never a problem.
