I don't know how the Elite's switch configurations are, but the prior web mods I saw for older Sovereigns would of course not work with the GT as it has different switches with different configurations involved. I had to test the main disc iron mask on/disc iron mask off/all metal switch on the GT with a multimeter to figure out what it was doing, and then configured a remote PP for that. I can now bipass control of the main switch when my remote PP is plugged in. It has two positions. One giving control back to that switch, and thus allowing it to run in any three of it's positions it's set at on the GT, or the remote PP thrown the other way will take control away from that switch and force control over to the All Metal track/fixed/or PP switch...And thus the GT will then run in whatever mode that switch on the GT is set at. So, with the all metal switch on the GT set to PP, when I throw the remote PP switch one way the GT will go into PP mode since the switch on the machine is set to that, or the remote PP will throw it into one of the two all metal modes if the GT's switch on the faceplate is set to one of those.
If anybody wants the schematic/pictorial complete with switch and other part #s from Radio Shack let me know, as I drew up a pictorial with pretty detailed information to make it easy for anybody to do who has some minor soldering ability. The remote PP plugs into a stereo jack on the back of the GT, so I can unplug the GT from it if I want to throw the control box in my chest mount bag for water hunting or something. I've got the remote PP switch hanging down from a bike end bar hand grip, so it's configured just at the reach of your fingertip like it is on Whites and other machines. The whole mod is pretty darn easy. A jack on the back of the GT. Clipping one of the wires on the GT's dicrimination switch, a little soldering to the jack and the remote PP switch, and that's about it.
Don't fret about clipping one of the wires on the GT's switch. If you unplug the remote PP the GT stock switches work just like they always do without it plugged. That's why I used a stereo jack, because those jacks are designed to connect or disconnect connections based on a stereo plug being plugged in. That's how your machine disconnects the internal speaker when you use headphones, and thus how I return control total control back to the main switch when the remote PP is disconnected. As said though, the GT's stock switch still works with the remote PP plugged in. You can set it to whatever you want and control it from the main switch as normal. Basically the remote PP just bypasses whatever that switch is set to on the GT when the remote PP is thrown into All Metal mode, at which point control is given to the GT's all metal switch and whatever that is set at.
Oddly, though...Now that I have a remote PP I rarely use it. These days I prefer to PP in discrimination mode by wiggling the tip at a target. It does fine that way, and I'm sure even using the center in discrimination mode would also work just as well. I find that PP mode often can not hear very deep targets at all sometimes, where as they sound off fine in discriminate. I also find that sometimes PP mode will sound off over a large area due to microscopic iron in the ground or something, where as discriminate will only sound off right at the target.
Ron, those AAAs should work just fine being that they are 1700ma (Are they?). The stock rechargeable pack is only 1000ma, but even good quality cells of about 750ma or so should run just as long as the stock pack, as those Sub A cells in the stock pack are rather ancient technology. A good modern nimh cell in an AAA or AA with even a bit lower capacity probably really holds as much capacity as that. I often find a good quality nimh will charge to 300 to 600 or more higher capacity than the label says, because my Accucel 6 charger displays the capacity put back into the pack as it's charging and when done. I suspect you didn't charge that pack well enough yet, or you screwed up wiring them in series and actually have a few in parallel, which will lower the voltage. That can happen to even the best of us if we aren't paying attention, as I speak from experience screwing up like that.
Thanks for checking deep targets with slower/faster sweep general long sweep speeds to further that debate we are having in the other thread. Good info. Can I ask what kind of soil you have? If it's somewhat mineralized then that might require a slow sweep, or it could be that that coil prefers that for best depth. I'm not saying one or the other is right in this fast/slow general sweep speed debate, as I used to feel a somewhat faster sweep was deeper but am open to being wrong about that and need further testing in my soil myself to firm things up one way or the other for me. Of course my 12x10 could even change those variables, if not just my soil conditions.
