40 Fathoms Grotto used to be a great place for training. As the name implies it is 40 fathoms deep, or 240 ft for you landlubbers. Located in Crystal River Florida, the facility provides a controlled environment for deep TRIMIX training. It’s my understanding that the facility has been purchased by a commercial diver training agency, and is no longer available to recreational divers. This is a shame as it was one of the few training locations with the depth necessary to perform this training.
I hope they reopen to the recreational market, but in the mean time here are a few shots we took on a training trip during the renovations.
