Modified Excalibur

[Joe Beechnut OBN]

Final Modified Version of my Excalibur. Was able to silence the machine in rough waters by removing all of the knobs except one which ..and it is sealed from the saltwater by a o-ring and custom easy, fine tune knob. Stability is very good close to shore where water is smacking the control pod and the coil wire... I do need to get a shorter Allen set screw for the sealed on/off threshold knob I made...but for now the allen is coated with aquaseal and the internal shaft on the pot has a plastic cover to break contact with the SS knob shaft. Not real happy about the toggle on the handle which is used to go between PP and disc. But I had a bad batch of the IP68 yellow momentary push buttons ..... had two fail on me.... I was right in the middle of a good hunt and had one go out on me..so I pulled it out and chopped it off to finish the hunt., got home and made more changes to the excal.  Hopefully in the future they can get better quality switches. 

And special Thanks to Steve detector rods for rushing a few of the cam locks for the lower shaft..., so much easier adjusting the coil for the hunt, which is a very important part of coil control and Pin pointing the target.....

Picture of the hunt I was in the middle of and the yellow IP68 button went on me.. I can not stand to hunt in disc, which was the mod it was stuck in..chop-chop and all was good..

Great job, as usual.  Really turned out nice and solid looking. I envy people who can construct thing like that. I wish Minelab would have made one of those for the GPX 5000. Imagine that being waterproof 🤔 You got some nice looking gold and silver there too!

Nice looking modification that you have done, I hope it works well for you and lasts a long time.

Great finds again and the age of some of those rings are nice. The silver ring looks better since it was cleaned, fo you think it will get any better, or has the salts gotten to it that bad.

Good luck on your next hunt.

Hello Joe, great job.

Plastic head ip68 pushbuttons are not so good quality. You definitively have to check this one:

Switchcraft Series 913 Sealed Push Button Switch. It is IP68 rated when mounted on a panel.

It has a great built quality and a rubber boot to seal the momentary switch.

Ibhave used these in my etrac build back in 2015....

Wow! Beautiful oldies you pulled out of the water there Joe, congrats! Love the Stealthy Excal too!

I will! Thank You! 

I've had good luck with the yellow push buttons the last 3 years but I got a order in.......Now  I 've had a few go bad within aa couple hunts. Quality control must had been sleeping that week.

What if the intermediate knob shafts were to be made of plastic? 

Also, my detectors and pin pointer will sense carbon fiber.  Thoughts on this?
