I have been using one for over Eight Years.
Great for "Before, During & After" views of a Project, along with Logistics and records of everything.
Also makes the task of recording nameplate data so much more simpler, efficient and cleaner!
My "Wish List" is to get a moderately sized SLR Digital Camera, several lenses to mount on it, and multiple FLASH modules to store bits'o data on!
Back in 2001 / 2002, when I was doing a lot of Bank Branch Surveying, the SLR with multiple lenses would have been soooooo nice!
On those Surveys, I was using two different Digital Cameras:
* My personal 2.1 Mpixel camera - with 32 MB Flash module (used the most),
* Company-Owned Digital camera (??? Mpixel), with 3.5" H.D. Floppy Disk storage (very sluggish, not very much storage per disk, too many read/write errors, and other annoying issues).
