The R300 is designed for an operational depth of 300 feet. For this test we are going to the bottom of Medina lake which is around 120 feet near the dam. The R300 is a one man, and is one atmosphere sub. Inside the sub is set up like a re-breather. Sensors monitor oxygen and CO2 levels. Pure oxygen is added as needed. You could stay underwater for 3 days if necessary.
The sub and crew depart from my dads house in Devine TX early Wednesday and return that afternoon. We still need another diver. E-mail for more info. Thanks.
