I always hunt in the numerical mode & im not a newbie. The reason is that it is alot easier
to interpret the #'s rather than where the crosshairs are. especially in trashy areas, it allows you to quickly determine the GENERAL RANGE
of where a target falls (in conjunction w/ tone discrimination). You should not interpret any one number to definitely be a certain target, as the numbers just average what the target(s) are.
This has been my experience, I may not be 100% right on this one, but i do enjoy hunting in the numerical mode.
thank you
P.S. I usually do verify targets by switching to the crosshairs before digging. Then I verify conductivity, and exact depth w/ my Periscope.
