No DMT activity this weekend (well I’m sure there was, I just didn’t sign up for it), because I had planned to go to Vobster with my girlfriend for just some diving, something I hadn’t done in a while! She wanted to try out her brand new drysuit, I wanted to explore some features without a gaggle of students in tow and we both wanted to refresh some of the OHE skills we had picked up doing the Cavern Diver course in Mexico last January. Unfortunately we arrived later than I had planned and only had time for two dives, but still it was an excellent daytrip.
| Dive | Max/Avg Depth | Min Temp | Time | Consumption | SAC |
|---|---|---|---|---|---|
| 1 (Aircraft) | 13.1m/ 9.8m | 13℃ | 40 mins | 120bar/ 1440ℓ | 18ℓ/min |
| 2 (Tunnel) | 21.3m/ 12.2m | 10℃ | 19 mins | 74bar/ 888ℓ | 21ℓ/min |
Higher SAC on the colder, deeper dive that involved an OHE, still close enough to my benchmark of 20L/min. Only kit change was the addition of an old-model Uwatec digital depth gauge, bought on eBay. I had been concerned about having replaced my traditional console with a Suunto Cobra, if it suffered a failure I would be without not only contents gauge, but depth and time (and less importantly, temperature and max depth, but still), so I wanted a backup. Very nice piece of kit, clear display and easy to use. Only problem was it didn’t sit properly on my wrist and adjusting it in the water made my drysuit leak a little. My drysuit has a retainer for wrist instruments, but only on the left. I’ll probably upgrade it to the current version when the non-replaceable (!) battery runs out, with a bungee mount rather than a buckle strap.
Back to DMT next weekend…
