KOMBI is a digital survey device that I just found. http://kombi_measuring.tripod.com/
Neat eh? So the Kombi 3&4 does all 3 measurements we need, only KOMBI 4 is able to save 1000 measurements. I dont think any of these have bluetooth but i'm not sure, but really, how much time do you save in a average 12 hour survey with automatic bluetooth transfer? 30-45 minutes? I have sent these people an email in hopes that they still have the instrument in stock.
