Maybe your knob needs readjusting. The knobs on an Excal II are easy. The yellow knob on top pops off. There is a small nut under there. I personally replaced the factory knobs with after market ones. There is a set screw on the side of the new ones. The knobs are bigger, and have a pointer on them that I can feel with out looking at.

Pop the cap, tighten the little nut, do not over tighten. If yours doesn't have a nut, some don't, buy set screw replacements at The Shack or from Anderson. And the only two knobs that should click are the Disc/Pinpoint knob and the On/Threshhold knob.

I'm new here trying to maybe return the favor and add a little! Great info on this and another group.

Yes, your knob is clearly positioned in the worng angle and should be rotated back to "Auto" when the knob has been clicked tothe left looking down on the machine as you use it.
I have an older Excal 800 and it has 2 hex set screws on each knob. I was missing a knob (second hand unit) and bought replacements on ebay for $14.
They have brass slot screws on the side. Nice knobs. Still, my post on the Threshold was rather stiff and even the new knob slipped. I moved the double set screws knobs to the most demanding
posts that were the most resistant and now no problems with knob slippage. Sensitivity goes from Auto, and "clicks" to manual on my unit as I turn clockwise viewing from the user position. So I think this is the click TomcatPI is mentioning.

See if there is s side set screws(s). If not, the knob can be removed prying up the top round cover on the knob. You can then loosen the knob further and position it properly . I would click the Sens to the off position and then position the knob so it indexes the white line to the "Auto" position and tighten there. replace the top "cover" of the knob.

That said, my machine again has two side hex set screws that tighten the knob to the rotating posts. I like these even better than the replacement knobs so I have a mix now. The only problem with the originals is that the hes screws threads into plastic threads of the knob and can strip. I am looking for small inert screws for the new knobs that can replace the brass slot screws. The new knobs do have a female metal assembly that receives the slot screws but the slot screws are brass and one quickly deformed. Being in the field and having a knob spin loosely is very frustrating. This should not be rocket science. A good knob should have metal female threads to receive a set screw that has a Phillips or a hex configuration. I think stainless steel is best.

I changed poor and cheaper screws in my business when I had a chance to control that and it has saved mega assembly time. "Small Parts Inc" and "Mcmaster Carr" have a great variety of screws from Torx to hex etc.

I've had problems with the knobs on two different Excals now. I just ordered a set of Anderson knobs and hope they solve my problems. I don't understand why Minelab can't make the posts 3/4 round with a flat side, with a corresponding hole in the knob with a flat side. Then reinforce with a set screw that goes against the flat edge of the post. Most other electronic devices I've owned in the past like stereos have this sort of knob / post setup, and there has never been a problem with loose or slipping knobs.
