I watched this little bit of Hollywood fantasy last night. Totally unrealistic, don't have to be a cave diver to figure that out:
1. Evidently you no longer need an FFM for underwater comms, a plain double hose reg will do.
2. Nifty little handheld sonic mapper. Press a button and you have the entire layout of the cave in front of you on a screen. Works above and below the water.
3. Divers slipping out of their tanks, swimming 10feet through a tight squeeze, mapping the larger cave with #2, looking around, twiddleing thumbs, squeezing their way back out, all on a breath hold.
4. Rebreather the size of a breifcase that allow you to stay down 24 hours.
5. No need for stage bottles with #4.
6. Rambo, meets Indiana Jones, meets Top Gun, meets cave diving.
7. Allowing a DPV to run into a wall causes an explosion.
8. Said explosion and the resulting cave in, do not disturb the sediment.
9. Etc, etc.
Basicly, the most belivable thing in the movie is the subteranian parasite that turns humans into flying amphibians with huge claws that see via echolocation.
Ahh well, at least there was some cool scenery...
