My deepest dive on a single tank was 57m, and I wouldn't recommend that or try to repeat it. Down currents can be terrifying.
You're right that 45m puts of out of range of most divers, but it is definitely still a doable dive with decent divers on twins and a deco stage.
The visibility in the photo looks decent for a silty bottom, I wonder what the current is like since it is in the Nile.
I am also curious about what caused it to become submerged in 45m of water 1500 years ago.
- smileysteve 7y ago57m on a single tank would just be so short too; air goes quick at that depth, and the longer you stay down the longer you have to take getting up.
- diveanon 7y agoit was definitely not the plan. I remember being hooked on the wall and seeing my bubbles descending behind me. That dive felt more like mountain climbing than diving.
- nradov 7y agoSome walls have vicious down currents, but if you just swim away from the wall a few meters the current will decline and you can establish positive buoyancy.
- diveanon 7y agoYou're right, but I wasn't willing to take that risk. One of the divers in my group was already in a mild state of panic and I didn't want to chance them letting go of the wall and descending another 10m. I had a plan to deal with the current, but oxygen toxicity is another thing entirely.
- nradov 7y agoOxygen toxicity isn't really a factor at that depth; you'd run out of air on a single tank before experiencing any toxicity symptoms. The immediate concerns would be narcosis and hypercapnia.
