1st - I noticed this was your very first post - so, Welcome Aboard Nvv!
I moved ya from HELP! (HELP! section contains guides tutorials on how to use the new TreasureNet.com software) over to WHAT IS IT? for more exposure.
Until a member pipes in - you might consider jumping over to Aruba and sending them an e-mail (e-mail address at bottom of page). Also, I jumped over to their Aruba Forum and searched on "metal detecting." You might go through the threads. Hope this helps!
