Just got a new 5000 and swapped out the stock lithium battery for the GSPP system. But I seem to be having lots of problems figuring out where to set the amp and getting the machine to quiet down. Unfortunately, no instructions came with the GSPP to assist in setup. I took it today to a site where I had used a borrowed 4000 last year that also had the GSPP and it was very stable and quiet back then. Today with the 5000 I had difficulty even being able to auto tune the machine as all channels had at least some noise. I switched to a less sensitive timing, lowered my gain and stabilizer, etc, but it didn't seem to help. I could switch over to Cancel and it got quieter but I lost most of my depth. I have the knob on my GSPP set about halfway. Maybe that's too high?? Is getting the machine to settle down a combination of setting the amp, gain, stabilizer, threshold and other audio settings? I really need some help with this as the detector is useless as it is now. Guess it could be a problem with the new 5000 or GSPP, but more than likely its operator error. I should note that the first time I used the 5000 with the stock battery is worked fine and was quiet with fairly hot settings. But when I went to the GSPP I can't get it stabilized. Thank you for any assistance ...... Bill
