How do I save the changes I make in a current program? I know it's probably in the manual but I haven't had a chance to read it all the way through yet. Also, is the pinpoint volume adjustable? As far as I can tell, it is not. I DO know about normal and sizing and use it on sizing. I just wish it had a modulated audio like the disc which is adjustable by lowering gain. I see a lot of Minelab's presets gain at 24 and above but I really like a modulated audio on the disc and find between 15-20 works best for this. Is the pinpoint mode tied in to the disc volume or separate? Thanks in advance...HH George
