No they weren't Deep Dives. I am not sure what they were, smaller and had a kort nozzle at the rear. Dynamic divers, but never made it into the water (not while I was looking anyway). Anyway you can still buy the HFM kit, they perfom very well and can be easily converted to a pump system to make them static divers. They must be the chapest way to get into the hobby though
No there weren't any other non-naval subs (I will have one there next year hopefully).
