Hope you can put that bad boy back together! Are you working on that EMI shield? Thanks for posting this, I've always been curious how these looked inside.
I'm sure the '75 will be better than before, but only trial after trial will tell. I totally agree with you, the connector must be for future software downloads! As for what makes one more powerful, I suppose a good analogy would be, say, a Pentium 2 CPU from the late '90's, and the new quad-core CPU in use today. There are multiples squared of reasons one detector is more powerful, or better discriminating, but the hardware definitely plays a large part. However, the software must be programmed to make the best and most efficient use of that hardware! Like having a 500 horsepower car, you must press the accelerator to the floor to get the most out of it, or, you won't climb that hill!! LOL!! A person can take a mediocre detector and increase performance by doing a number of things to it. One being, take all the + or - 25% resistors out and replace them with + or - 1% resistors, more expensive, but if one cheap 25% one is 25% high, and another 25% one is 25% low, then there is a variance of 50% tolerance, and that is a lot of OHMS. Also, clock speed of the CPU and also the oscillators must be matched for best performance. And so on!! Well, enough of that! As for the switch trigger, no problem as far as the wires go, there are only three, the middle wire for search mode, and one each for GroundGrab and pinpoint. And speaking of the switch trigger, when I disassembled mine, the switch crumbled before the attachment nut came loose!! Modifying the area where the switch sits, relative to the control panel, isn't going to be much fun, if you intend to keep the stock pole assembly. If, however, you go with a F-70 style pole, then you may use a really sturdy switch, such as the Tejon uses! If you notice the small plug at about the one o"clock position on the lower picture, those are the switch wires, although the view shows what appears to be two wires, there are actually three. My net photogs will never win any awards, but I may try to post a few more, if they come out alright!! Thanks for showing interest, Ian! Perhaps we will learn something from this little adventure!! Great hunting and good luck, Ian!! Regards, Richard.
in my experience a lot of rf issues start in the long wires.
just wondering because it will come unpeeled from the inside of the case if it gets cold.. i have a nice 50 yard roll of the good stuff with a 3m backing as you probably know 3m self adhesives do not come off without chemicals. especially since your sticking it to a graphite coating.
