  1. Thanks for all the advice on the removal of the Jetco knob...It's been awhile since I replied on this, so much going on now days that I assume we are all aware of. Anyway...The knob should have, I repeat, should have, pulled right off. This wasn't the case with this one. It almost seemed welded on. The fellow who gave the detector to me rented a house from me & kept it in the garage, when he moved he asked if I would like to have it & I told him sure & it just stayed there in the garage since 1996. At the time I turned it on and it worked. This fellow installed stereos in vehicles for a living & he might have put some kind of King Kong super glue on it. I had to eventually give in & cut it off so I wouldn't tear up the spline or even the plastic housing, however, before doing so I checked online to see if any similar knobs were available & there are hundreds available. I'll eventually get it up & going again here pretty soon so it can once again detect a half-dollar with no more then a thin coating of dust... Thanks again to All!
  2. Thanks all of the advice & suggestions...I just got in & will post if I eventually get this newsome off. If so, I'll post a few pics as well. cowtownkid
  3. On the depth & location of water main...I sure did. I was one of the oldest mains that size still in service. Left the Holly treatment plant and meandered to the Northside. It cut across a large church/private school property. I started at an Arial crossing (on piers) about 500 ft. away. At this point with pipe exposed, I set the Transmitter part of box on top of the main. I just traced towards the property, however, the lot had been filled in over the years. At the point of excavation, I just barely got the box far enough away to avoid any interference between the two units, using sensitivity adjustments & raising Receiver box 3 ft. or so off the ground. I believe it was 14.4 ft. deep from Top of Ground. Surveyors came out & GPS'd it. Anyway, school & church was demolished & a shining new 20 story Pier 1 Imports Headquarters was built. Pier One declared Bankruptcy a year later...Go Figure cowtownkid
  4. That is kinda what I have been thinking...This dang thing is just to tight for what it is... & it looks like the screw could very well be under that thin decal... Appreciate the info!
  5. Yes, what away for an introduction...Jetco Mustang, Jeeze. I started metal detecting in 1971 when my dad finally gave in and bought me a Jetco Treasure Hawk for my 11th Birthday. I actually wore small holes in the bottom of the coil. I was hooked. Traded to a Garrett TR in 1973-74 & kept upgrading. I actually made a career using metal detectors, partially anyway, working for the City of Fort Worth Water Dept. for 31yrs. 17yrs. as a Supervisor. I first learned how to use the Gemini II back in early 80's. Tracing lines inductively/conductively & also using as a two box unit locating MH's & water valves etc. I actually located an old 24" cast iron main laid in the 1920's near downtown with a backhoe standing by...The main was a bit over 14' deep. It took a while, but I had it dead on. Anyhoo...enough of that, I was given an old Jetco Mustang in 1991 & it has been hanging in my garage ever since, never paid much attention to it until recently. I put a new 9V battery in & it actually works! However the tuner needs a good cleaning. I completely broke down the old unit except for the circuit board. The single knob on the Mustang secures board to upper housing & I got the nut loose with no issues, however, I cannot get the black plastic knob off the plastic spline? No set screw is visible & I have cleaned & lubed the spline area. I am wondering if there is a set screw under the top decal of the knob? I just don't won't to damage or mar this old vintage unit. Any help would surely be appreciated. I have read Steve's articles & reviews over the years & they are absolutely informative & helpful. Thanks to all! cowtownkid
