[PSUBS-MAILIST] Snoopy dive report

[Alec Smyth via Personal_Submersibles]

Hi James,

I don't know if you want them to last or if you want to stress them
intentionally. If you want them to last, my theory is that they will be
fine if you use only one of them. Lets see!

All the best Saturday, please let us know how it goes.


Thanks,

Alec
