GSI vs. Madsen

I would urge you to also consider the distributor you are buying your 
instrument from.   The installation, calibration, and maintenance from 
this distributor is another  "feature" you'll have to live with.  
I don't know the geography of Montana or where you'll practice, but 
another consideration should be can these manufacturers/distributors get 
service or loaner equipment to you when you need it.  Also if you'll be 
using sound field,  who can perform that calibration least expensively.

The GSI 16 is a good instrument with a long history of good performance.  
The only fault I have found with the instrument is that it often requires 
a new display circuit board eventually as the display will fade over time 
to become unreadable.

The Madsen Orbiter is a very new unit and I know of no one currently 
using one.  I believe, however, that the unit can be connected via RS-232 
cable to a computer, and software is available to also connect that 
computer to a Frye Real Ear system.  The software then allows all 
information from both instruments to be combined and manipulated.

Note: I am a medical instrument repairman working primarily with audio 
instrumentation.  GSI and Madsen are not my manufacturers, so I think my 
opinion is unbiased.
