Some say (no not the stig!!) that they don't need the main unit, fine, but I bet they either DID have it and now don't need it after getting really familiar, or, they have never had it and arn't qualified to reply on it.
I Do have it, I use it, lots! to make quick settings changes, swap programs quickly, have a glance at the horseshoe, check if the ID number is under 30 in which case I don't dig, if its a iffy repeatable sound and the target ID shows nothing, then dig dig dig! besides, its fun to see what target ID it suggests and try to guess what the meal is before you dig it out.
If you can stretch to it, get it. You can always sell it if you don't want to keep it, (yeah right!!)
