Thanks for the pitch-gauge tipe Scott.. ! R I've been using mine (I-phone) for cases where we walk in and see a pressure-booster system in a Boston-area house with public water.. I do a Google map satellite view over the house, back-out and bang.. there's the the local standpipe hiding in the woods, explaining the pressure-booster.. I've also used it 'look' at a neighborhood to see if I can see the roof from an adjacent street.. It's a very good tool in many ways and has increased my productivity in regards to appts, field-management of other inspectors, etc. I just got an I-pad but mostly for music-stuff... We are doing a lot of old covers (Ventures, etc) and it's a quick way to find out what 'positions' the guys are playing parts in...
