Hahahaha, you florida guys crack me up. You really don't have any concept 
of what being cold is like, do you? A Patco heater would be like spitting 
in a tornado for what Ingemar is diving in. He is doing tons of deco, you 
moron, he would have to get wired up like a terminal box and use truck 
batteries for enough patco heaters to do the job.

These unit are for recreational diving only.
