We’ve used a Mayfly successfully with a variety of SDI-12 sensors from different manufacturers, including ones that require 9v or 12v excitation. I usually use a custom simple logic level converter with most of them, similar to the Sparkfun item Greg mentioned above. However the only ones that gave us problems were the YSI 6-series sondes, so I don’t have any tips for working with those.
