The way I learnt is getting someone to hide it, and then finding it, give it a try.
The method I use is to scan around on SEARCH, until you get to below 8 foot on the LED's , then swich it to LOCATE, scan around further, following the sound on the locator (high pitch getting closer) then once you are confident you are fairly near, start to turn the PIN POINTER slowly until you hear nothing, wave the locator over the ground, if you still hear nothing then move the PIN POINTER back until you hear the sound and then you should be more or less on top of the ferret.
