Just came back from the beach this morning with the Nox 600 and updated firmware... I was in wet sand, Beach2 sens 20 (noise cancelled and ground balanced) and moving along slowly, enjoying the day when a young lass asked me how it works.. I wanted to demonstrate how it works by tossing a Canadian dime into the sand and wave the coil over it and... nothing..?! what? It wouldn't register against the coil.. A penny would.. but not the dime.. what the..?! The Makro pinpointer sees it ok, but not the Nox.. I tried in Park1 Park2 modes and nope.. but in Field 1 it will see it..
Maybe I have this all wrong but doesn't the different mode settings basically change what is notched out... that the one item will still read as the same number in all mode? The dime came in as 17 in Field 1 mode.. But why would it not pick up in other modes?
Bottle caps this thing can find... I wonder what else I might have been missing out there..
Am I understanding this all wrong?
All targets
will not show up the same using all modes and settings.
I have seen targets change as I experiment and switch modes as I swung over them.
Look up the bottle cap trick for identifying that hated trash target easier by switching to the 10kHz frequency, for instance...changing just the modes is not the only thing that affects target behavior.

Your coins are weird, a modern Canadian dime is the same as iron to most detectors.
The Nox leans and is weighted toward different combinations of conductive ranges depending on which mode you are in.
The rejection you have preset is different with each mode, the speed and iron bias will affect how the Nox reacts too as will conditions you come across hunting in wet sand or water.
The 17 you saw was the result of your settings in Field 1, could be normal and consistent for this mode or you could have just had higher falsing tones and numbers as iron often will do on many detectors, probably using Field 1 accentuated this falsing effect.
17 is not a normal number for a modern Canadian steel dime.
The other modes you tried correctly rejected this target as iron.
To answer your question yes, you are not understanding the Nox so great...yet, and you also need to brush up on the metal composition of different Canadian coins both old and new.
All will become clearer with some learning and new knowledge.
