Special Note on Balloons:
Balloon Comparisons: After 60 years of production Kaysam the only US manufacturer of meteorological balloons has ceased production.  As a result the only manufacturer high quality meteorological balloons is Totex of Japan.  These balloons have a high manufacturing quality, however their neck sizes may be different than stocks of  Kaysam balloons that were in use by various users.   For some users this will require a change in nozzle injectors or nozzles.    See balloon size comparison pages for 10 gram and 30 gram balloons.
