Ha, I perhaps used some bad terminology. It really wasn't dumbed down from a user standpoint, they tried to make it less susceptible to emi which made it somewhat sparky and chattery. I and some others didn't have a problem with it being sparky, but others did. By adding dst it (maybe) was less affected by emi, but it took a pretty good hit in depth performance and seemingly was a little less sensitive. I know a good percentage of hunters wanted to wrap the F 75 around a tree and gave up on it. That's too bad, as once one learned its language it really was a terrific detector. HH jim tn
