DISCRIM accessory KNOB ?

Harvdog42 made some. Haven't seen him post in a long time. Machinist by trade. He wrote a book on some techniques to make some machining jobs easier to set up.

Here is a link to when he made some of the knobs:

Thanks, tvr. I sent him a pm, but you're right about him not posting for quite a while. I may have to make my own knob, but those that harvdog made, sure look good.
 
Glue on a large button... KEN
 
Well, I decided to make one, though all the suggestions would probably work just as well. Picture size I can upload here is limited, but I did post some pics in a thread on treasurenet in the tesoro forum, if anyone wants to see. ^_^
 
Thanks for posting 'em, tvr!
I gave my accessory knob a workout today. Found just $1.37 in mostly clad, and one '57 wheaty. Not what I was hoping for, but the knob worked like a champ! ^_^
 
Could always use a hubcap :poke:
 
That must have doubled the weight of the detector!:surprised:

LOL! really, trying to dial in the space station or something... does seem to be a bit much. guess the bigger the knob, the better it will discriminate. :wacko:

Nobody else thumbs the disc to help figure out what's beepin'..?
The big knob is for function, making it easier to turn by thumb - the stock, small knob doesn't move easily. It has nothing to do with how well it discriminates.
I usually set just above foil, then thumb up & down to see where the target breaks up. Takes about two seconds and (sometimes) tells me if I have a pulltab, zinc or something better.. too much work for some folks, I guess. Suppose that's why so many like TID toys.
Might as well just set your disc at zinc ¢ or max, and leave it there... :rolleyes:
 
Been thumbing the Disc knob for years. I liked the poker chip idea. Just seems like a 1/4" thick metal knob is a little over kill.

buy a detector with a screen :blowup:

Tesoro's are for set disc and dig, at least where I come from.

I disagree; they're for learning to use a simple and reliable tool as efficiently as you can. I don't want to miss good targets, and I don't want to dig all the crap. Maybe you like a screen. I'll thumb the disc, thanks.
Where I come from, my thumb can spin that big knob from all-metal to max disc (or anywhere between) in 1/2 a second. Another full second or two to try and figure what I'm digging, or pass. Yes, the smoothness and volume of my beep also helps, just as seeing where the target breaks. Even with my Compadre, I'd want to thumb disc to suss it up; I'll leave set & dig to whomever I loan my Compadre to.
Why would anyone experienced just "set disc and dig" when you can figure out where your signal breaks up? Sounds like a lazy bubba to me... :rolleyes:

BTW - top of the knob is only 1/8" thick. No problem to chuck it again and turn it thinner, which I may do... It's turned from 6061 T6, so it's plenty tough. Next one I'm making though, will be a basic carbon fiber lever with similar thumb hole, bonded & screwed to an aluminum hub. Should allow for easier access to the on/sensitivity, weigh less and be more discrete. I'll post pics for your amusement. Meanwhile you all can set just disc and dig. ;)
 
Many moons ago a guy posting here often talked about thumbing the disc to ID things. It sure can be a useful technique.

Here is one of tabdog's old posts on thumbing the disc: http://www.findmall.com/read.php?17,847246,849031#msg-849031

A single tone Tesoro has it's own language and can provide a lot of information about a target in the ground by using more than a very basic set and dig approach. Thumbing the disc is one of the tools available. Coil position, target sizing, depth, sharpness or smoothness of the edge of the beep, elongated beep from one direction and not another are some others. Lots of information available from a seemingly very simple detector.
Cheers,
tvr
