interesting....
i took the 300 and the 100 out together.
i marked out an area and swept it with the 100 in all metal mode. made sure the area was clean.
then i put two coins in marked spots and swept it again, in all metal mode then again with varying
levels of discrimination. when the setting was just above the rejection threshold (no detection), i dug up and
reburied the coins and swept again. the coins were picked up easily as expected.
I then swept the area with the 300, firts with the recommended initial settings.
Nothing! the coins were marked so i knew where expect a sound. After a lot of manipulation with
the depth control and discrimination i 'located' the coins.
I found that unless the depth control is at full whack it will not see anything reliably. I did find that the discrimination
setting was just about the same as on the 100 when i was consistently finding the coins.
Conclusion? the 300 works, and if i overlook the flashing indicators on the LCD i can detect pretty much the same as the 100. BUT, if i watch the LCD i see the indicator reacting to the coins at a lower depth setting or a higher discrimination, but i get no audio tone!?! i can't walk sweep and watch the display all at the same time unfortunately, so i will have to run
it in a less discriminating setting and dig everything (which some say should be done anyway).
another interesting thing, i had the headphones on stereo, i usually have it on mono, and discovered that depending on the movement and the target the 'beep' comes from one side or the other but not both. there is no mention of this in the manual, so i'm not sure if it means something.
Anyway, i still need to do more testing and trying before i fully get to grips with it, but i don't think it's as bad as first impressions gave.
