No problem---I have to head up to cave country on Friday for a week or so and cannot make it Saturday. Ocean Divers will run a Double Dip for you Saturday morning...just call them up and they will do it.

I sure would like to go with you, but maybe next time!!

Excellent, thanks!

Yes maybe when you get back... I'd like to talk about your trimix class too!

Please look at this thread and please pay close attention to the original post and post #35.

As a tickler....look at this video I made yesterday during one of the cave refresher classes.

Yesterday brought me back to the Spiegel Grove. I have been planning engine room / machinery space video dives for a while ... Its 130 feet deep in this, the forward machinery space so gas goes pretty fast & deco builds up quickly too. Lots of silt in there and the water is not as clear as on upper decks. There is no water exchange in there as there are no holes in her side and only small openings to get inside. There are layers of silt & what appears to be rust in the water which slightly restricts visibility.

This video taken 10/26/14 shows the entry vertical via a trunk (shown early in the video)down two decks. The video shows the boiler, (Spiegel Grove was powered by 600 pound steam.), and air compressor, one of the fresh water makers/condensors. Water was made by auxiliary steam flashing sea water to its boiling point and collecting the condensate, pure water.

This is definitely an advanced wreck dive due to several factors. Silt, overhead environment, percolation with open circuit, several lines and at least one tee in there that can be confusing if proper marking is not done and overall this is a relatively small space.

No one should attempt this dive without the proper training.
