hello xavier 6666 and all ,
sorry for not being on here for some time , bogged down in new job , less time to play.
as far as my detector goes , yes she is up and running and has been for some time , and is a usable deep machine , havent altered anything for some time now.
currently its a slimmed down version of the blind squirrel , but made into dual channel and has a simple op amp with red green leds attatched and also high low tone to indicate weather target rises at the start of the decay or at the end , and she works just fine.
but , not quite as good as i intended , noticed that all high conductive metals raised the decay at the start so made this light the green led and give high tone , and all low conductivity targets raise the end of the decay so made this red led and low tone ,
while testing steel was red and low tone , but in the field my discrimination isn't as good , turns out that rusty flakey iron results in green led and high tone along with "good" metals , so i still end up digging rubbish.
the idea was good , and it does discriminate , but , it seems not against rusty iron.
oh well , no real new ideas yet , poss going to play with an IB coil on a PI , and poss try to figure out a way to get an equivelent vdi scale on a PI , now theres a long shot.
