Pocketlogger Knockbox?

Has anyone ever used the knockbox?? If so, are they any good? Good quality?

a simple palm and free logger software and a cable adapter will give you all of the info that knockbox gives you for about 40$ or less.

try searching for pocketloggers and you'll get all the info you need. Good luck.

I allready have a logger (is it possible to own a GVR-4 without a logger?? /ubbthreads/images/graemlins/grin.gif)

I was thinking of maybe a more "permanent solution"..

I just picked up a Scanmaster-3 recently: click
Not exactly what you are asking about but I think the SM is quite lovely. Would not buy one strictly for the knock function but definitely works great for multiple parameters and no Palm to screw with.
