After switching over the students scuba tanks and eating lunch we decided on doing a drift dive at Sea Cave. For a drift dive from the boat we would use a “negative entry” meaning that we would empty all the air out of our BCD’s and descend from the surface as quickly as possible so that the group is able to stay together.
After a site briefing on the boat and quickly checking the students to make sure their equipment was ready the captain maneuvered the boat into position for our entry. Once in position, everyone quickly entered the water one after another similar to paratroopers jumping out of a plane.
As we descended I looked around and counted that we had everyone in the group together then Nate headed toward the Sea Cave leading the group as I followed along behind. We reached the entrance of the Sea Cave at about 50′ and stopped for a moment to check the current patterns, then proceeded inside up to about 20′ depth at the back of the cave. Frequently we find the highly endangered Hawaiian Monk Seals playing around inside the cave and I was hoping we would find some on this trip, but unfortunately there were none to be found today.
We were able to find one of the area inhabitants that are rarely seen in the area though, a Dragon Moray Eel. Because people can sell them for a lot of money we don’t often see them so it was a treat to be able to see one today. I will try to check in on him on future dives here.
After checking out the Sea Cave for a few minutes we headed back out to continue our drift dive of the area.
Normally when I have dove this site as we leave the Sea Cave we always drift to the West along the wall, but todays currents were backwards so we drifted to the East along the wall at about 70′ deep for about another 20 minutes before we deployed a delayed surface marker buoy and started to slowly ascend and make our 3 minute safety stop at 15 feet.
Once surfaced we realized that the seas had changed over the last 45 minutes that we were down and it had become quite choppy on the surface. Once the boat had maneuvered back into position we all swam for the current line trailing behind the boat and made our way back up the ladder.
Unfortunately the only injury of the dive came while floating on the surface waiting to get back aboard the boat when I was stung on the back of my hand by a jelly fish because I had forgotten my gloves onboard when I was assisting the students and reading them for their entry. I am severely allergic to jelly fish and insect stings/bites so I was very concerned. I had no idea how good he got me so as soon as I was back on the boat I readied my EpiPen just in case I started having an anaphylactic reaction to the sting. My chest started tightening making it difficult to breath easily but it was still manageable so I held off on administering the shot and applied a hot compress to my hand which was temporarily partly paralyzed from the sting and continued to monitor my breathing and pulse rate.
About half an hour later my breathing improved as we headed back into shore and I started to be able to move my hand again. Since the feeling was coming back into my hand, unfortunately so was the searing pain which subsided after I kept applying hot compresses to it for the rest of the night along with taking a Vicodin for the pain and 10 Benadryl tablets to help stop the rest of the reaction from the sting.
If anyone was to get stung on the dive I am glad it was me and not one of the students or other customers that we had on the boat today, so all in all it was a good day.
