Photography can be a tedious pursuit, even more so underwater where conditions can be very challenging. This leads to a regular issue in mixed dive parties. The photographers go slow, really slow. The other divers are ready to cover some ground. This occasionally means that the guys leave me behind.
While diving alone is not recommended, the risk can be mitigated. I shift to a different set of rules, a far more conservative set of rules if I am on my own. I keep the depth much shallower, to where I could do an emergency ascent with little risk, this is generally 30ft or less. I do not go very far into a cave, perhaps working the twilight zone, but not getting into the back recesses of the many little caves common along the Kona coast. These sort of rules are usually not much of a compromise. Almost all of the dive sites on the Kona coast can be enjoyed while staying shallow. Many of my best finds have been in the twilight zone of the little reef caves. Staying shallow also has the benefit of extending the dive dramatically, it simply takes far less air to fill your lungs when shallow.
Suck-Em-Up cave fits the bill. The maximum depth here is 30ft, and there are so many entrances and skylights that an emergency ascent is always possible. The rest of the guys are planning to sweep the reef face and take a deep excursion before heading to the cave. I am planning to simply dive the cave as I have several photographic targets in mind. I am first into the water, swimming a few feet from the boat awaiting Pete, Ben and Dennis. A loud pop and woosh announces a blown o-ring on an air tank for Pete, this will lead to a short delay. I signal that I am dropping anyway, they know where I will be. The cave entrance is only a few yards from the boat. I give a salute and they wave back as I slide under.
