I have just purchased a Pro Plus 3 for a trip to Bonaire in July. I would like to test this and have access to a 13' deep pool but cannot bring a tank into the pool. I would like to test this to make sure it's functioning properly before my trip. Does anyone know if I can use this without having the quick disconnect cable hooked up? I have been told that it should not be a problem as per the design of the attachment mechanism. Thanks
