Doug,
a bag of ice??? It was 9 & they had all melted by the time they got
to the dive spot. An epic sacrifice by Alec & Steve to dive that reef!

I get warm enough in Snoopy that it's definitely worth the investment to stay comfortable. I remember when Alec and Steve were diving down in FL, a big bag of ice helped to do the trick, but was a little 'drippy' just the same. Hey, for $2 I think that's a great way to stay cool!

I couldn't get the Kydex to vacuum around my mold before it cooled to much to still be flexible. I tried hitting it with a heat gun while it was under vacuum, but that just melted it.  Not yet discouraged!

Haven't tried it yet, just got my activated charcoal and micro sieve material for the filter, but I want to use a peltier water cooling module to chill the water going into the compressor's cooling jacket. The 6 chip one, with the water heat exchangers on the sides and cooling fins in the middle, has a design problem. The supplied fan can't pull enough air to really pull off the heat. Ordered a few sizes of radial fans to see if they work better.
