Hello,
  I am fairly new to skydiving, but am looking for a nice altimeter to purchase.  I have used both digital and analog altimeters at my local DZ, and I prefer the Digital altimeter over the Analog.
  Therefore, I am looking to purchase a nice digital altimeter.  It would be nice if this altimeter had log-book functions, and the ability to upload to a computer.
  So far, I have been looking at two different altimeters.  The VISO, and the Skytronic GFX.  I dont know anybody that owns either of these alitmeters, so I dont have a good idea on the quality of these models, or the pros and cons.
  Can anybody help me decide on a good digital altimeter, or give me some good review information on either the VISO or the Skytronic GFX and how they computer to each other?
  Thanks!
