LOL!!  Hey are you folks racing these things?  Other than the infamous CLR race I'm not aware of any need for precision weather instrumentation.

I use the scale used by kahp ho.  Unfortunately during the summer where I sail we will be on the "slow" level for the next three months with the possibility of reaching the top level when caught, not by choice, in the occasional thunder squall.
