I have the Node 2 and it does not do any data logging. However, I have to say I really like the Node. Nice large screen, configurable split screen, etc. etc. How do you like the 705, I am thinking of getting one - and really getting serious about the 705?
The 705 is nice. Much more reliable then the 305 which suffered from random shut offs, better battery life, but if you have a Mac, the compatibility is pretty bad. It says that it is, but it really isn't 100%
