Ok guys! I got the discount set up for the EBAs. If you contact Mike at KISS rebreathers he will sell the EBAs for $2500 each. You need to tell him you are from PSUBS to get the discount (coupon code PSUBS). Once they get the first ones built he will get pictures for you, because currently they only have prototypes now that they used for testing. He will keep this pricing available for psubs until the end of October and then he will release it publicly. Once I get pictures I will send them out. They are currently building 3 for the Pisces VI submarine.
Thank you,
Scott Waters
