way2cool Posted April 2, 2008 Report Share Posted April 2, 2008 So do you run Mono coils in DD mode? Quote Link to comment Share on other sites More sharing options...
Admin nuggethunting Posted April 2, 2008 Admin Report Share Posted April 2, 2008 Hello Guys, I really liked the GP3500 and found a few pounds with mine over a few years of poking around the Arizona goldfields. JP has always been a great contributor on the forums, so I'm also glad he is helping out on my forum. Take care,Rob Allison Quote Link to comment Share on other sites More sharing options...
2dach Posted April 2, 2008 Report Share Posted April 2, 2008 I feel like I'm on Jeopardy...except I don't know enough to be able to ask the question after looking at the settings on the 3500.So, what were these settings used for? Quote Link to comment Share on other sites More sharing options...
Jonathan Porter Posted April 2, 2008 Author Report Share Posted April 2, 2008 So do you run Mono coils in DD mode?Always mate, think of DD mode as the old Normal mode of the GP Extreme, Minelab re-named it to correspond with the way a DD coil can be manipulated to behave as either a DD only or a psuedo monoloop (hence DD or Mono modes). You can run a Mono in either mode, I just feel a Mono in DD mode behaves better in high mineralisation (a little smoother and maybe a touch more depth). I feel like I'm on Jeopardy...except I don't know enough to be able to ask the question after looking at the settings on the 3500.So, what were these settings used for?Those were my preferred settings for the GP3500 using a monoloop coil in both Arizona and also the vast majority of Australia. I should also point out they were designed to be used with a Booster/Speaker combo which explains why the Volume is set at half way (this helps cut out on distortion on bigger hits when using an external speaker).JP Quote Link to comment Share on other sites More sharing options...
2dach Posted April 2, 2008 Report Share Posted April 2, 2008 So, if detecting in the same areas with the same coil with the same speaker system BUT using a 4000 how might these settings be different?(It's always a good time when you can ask questions of people that you are sure won't make you feel like an idiot).I (we) appreciate you sharing your experience and knowledge!
