| Re: R M S Egypt 2007 Expedition Congratulations for these difficult dives. We did look for some of the unrecovered gold but I think it might have been guarded by some of the biggest conger eels Any gold found ? Et tu sais, Jean Marc, c'est interdit prendre aucun objects de bateau Merci beaucoup pour votre sentiments. Charlie |

| Re: R M S Egypt 2007 Expedition Charlie, On behalf of the team, thank you! congratulations on my behalf and, as said before, i do feel quite small and humble when reading this trip report. Still have a looooong way to go... johan Compared to rebreather divers like Dave Cooper, Martin Robson etc, we have a long way to go too. I hope our dives on the Egypt show that with good planning and preparation lesser mortals can expedition dive. Charlie |

| Re: R M S Egypt 2007 Expedition Charlie, Hey Johan, my sentiments also but perhaps we shouldn't be too humble because otherwise someone's head might start to swell. congratulations on my behalf and, as said before, i do feel quite small and humble when reading this trip report. Still have a looooong way to go... johan Seriously, Charlie et all, Congratulations on a fantastic acheivement! With the added bonus of such beautiful weather it must have been a very special week. Does this mean that the "not diving on anything with less than a five at the beginning" is going to change to "nothing less than a 10 at the beginning"? Well done!!!! John |

| Re: R M S Egypt 2007 Expedition Hi, Guys, has the land stopped swaying yet or is it just me?! I see Jon's response has disapeared, no doubt due to the technical problems RBW experienced y'day ![]() Feel really sorry that you suffer from seasickness so much when you dive. You did well to keep it under control during our trip Look fwd to seeing you at Dotty one day. Charlie |

| Re: R M S Egypt 2007 Expedition Hey Johan, my sentiments also but perhaps we shouldn't be too humble because otherwise someone's head might start to swell. As Martin (Parker) said to me about 6 months ago, these expedition type trips are often hard work with uncertainty the name of the game, more so than normal as the wrecks usually involve a long journey. Seriously, Charlie et all, Congratulations on a fantastic acheivement! With the added bonus of such beautiful weather it must have been a very special week. Does this mean that the "not diving on anything with less than a five at the beginning" is going to change to "nothing less than a 10 at the beginning"? Well done!!!! John I think 50m sounds just great at the moment Charlie |

| Re: R M S Egypt 2007 Expedition Well done to Charlie, John and the rest of the team. Being a sad git, if any profiles are available, id like to see them. What GF's did you run on the Vision? Did you run pure 02 at the end of deco if so for how long? Was 21m ins on the bottom time or run time? What set point were you running for the dive and the deco? What did the scrubber monitor show you and was it useful? Did you do air breaks and if so were they on loop or off loop? ATB Mark

| Re: R M S Egypt 2007 Expedition Well done to Charlie, John and the rest of the team. That's a good long list of questions! Being a sad git, if any profiles are available, id like to see them. What GF's did you run on the Vision? Did you run pure 02 at the end of deco if so for how long? Was 21m ins on the bottom time or run time? What set point were you running for the dive and the deco? What did the scrubber monitor show you and was it useful? Did you do air breaks and if so were they on loop or off loop? ATB Mark Jon and I used 5/90 GF on our Visions. Dive 2 my CNS got to 123% and as the Vision alarms from 3 hrs onwards didn't think we needed more O2 in our system so didn't increase O2 beyond 1.3. The 21 & 23 min bottom times are standard definitions of the time ie surface to beginning of ascent. I released the pellet at 8 mins on Dive 2 so Jon and I had 15 mins on wreck. We discussed at length whether to use a lower setpoint prior to shallow decompression but looking at various decompression programmes seemed to confirm that it would make little difference overall. We ended up adopting the KISS principle. 1.3 setpoint used therefore throughout dive. Tempsticks showed plenty of life remaining in Vision scrubbers. I had a look at other Vision handsets whilst on the 6m deco bar and this was the case with the other Visions being used. Jon and I discussed whether we could use our scrubbers again the next day for shallow safety diver role but we went (sensibly) for the cautious option of new sofnolime. On the Friday, I spent 2 hrs 10 mins doing 6m safety diver stuff so this probably proves that our caution was right. It would have been a little ironic if one of the safety divers had needed rescuing at 6m Neither Jon or I did air breaks, we didn't think they were necessary in our instance. I saw Simon doing an air break and he did his off loop. His CNS was up to 140% so that was probably what prompted him to do an air break. Longest dive (4 hrs) was on tables which were a very conservative option compared to the Visions. My VR3 was forced through all of its formal deco stops and was 20 mins AHEAD of my Vision computer when I arrived at 6m! It then ended up clearing just 5 mins ahead of the Vision. If you used a VR3 only and did all of its stops then you were in the water a long, long time compared to the Vision deco software. Anything else? Charlie |

(didnt think your were getting of that easy did you) Interesting stuff. 15 on the bottom makes sense with the run times. I have been using 10/85 to mimic the VR3. its comming out about the same running 3ish hour times. However the VR3 still has more deep stops than the Sherewater. ATB Mark Chase
