they can be a hinderance too...i have noticed that alot of people who have a machine with a screen spend too much time analysing it when they get a signal..without one if you get a good 2 way signal you dig it straight away...they do have there uses of course but it depends on the operator i think
Marmotte, I'm glad you didn't title this thread "LCD Display......"
It really annoys me when people do that, even worse when it's written in an official publication or advert.
well as an example...a hammered penny in the UK usually reads in the 20s on a DFX/XLT...however not always so therefore what the numbers are telling you isnt always correct...theres no substitute for the ear and the little differences from one signal to another...its not that i dont think they have a use as i owned an XLT myself and have a DFX as a backup machine now just that i am from the old school when i started detecting 30 years ago and we never had LCD screens then forcing you to learn the differences in tone...
I do find the display on my Hawkeye, an advantage, especially as it isn't a multi tone machine. If it's a steady ID, I know it's worth digging. I don't walk along watching it all the time though. It's only an aid.
the machines i used 30 years ago were single tone machines...you just had to listen for the subtle differences in the signal and after a short time it was easy..of course you could never be 100% certain but most of the time you got it right
