Notes:

The surf had come up a little from yesterday, which meant that the visibility would not be the greatest, and ended up being only about 20-30 feet. Since we had already completed 3 of the 4 required Open Water Dives, the students were given the option of making a second dive today as a “fun dive”. Since the visibility had gone down from yesterday, and the surf had come up a little the students chose not to do the additional “fun dive.

For the last dive of the students Open Water Diver course, Open Water Dives we went back to the sandy area at the center of Sharks Cove so that they could perform their required skills. Afterwards we took them on a short tour around the area, again taking them over rocks which made them go into shallower water to see if their buoyancy had improved.

One student still struggled with his buoyancy and used a lot of air because he was constantly inflating and deflating his BCD to compensate for his poor buoyancy. When he was too low he would air his BCD up, making him rise too fast, then he would notice his mistake and dump all the air out making him crash back to the bottom.

After watching this a few times to see if he would grasp the concept of what he was doing incorrectly on his own apparently he was not getting it so when he was on the bottom I signaled for him to add just a little bit of air to his BCD, when he did that he rose just off the bottom so I signaled that it was good, then motioned with my hands to use breath control to rise up a little and to sink a little. He seemed to understand and performed as I showed him, but then when we started the tour once again he was back and forth from about 5 feet to the bottom like a ping-pong ball. Hopefully with more practice it will start to click for him.

Dive 75

Date: May 18, 2013         Repetitive Dive: 3 of 3

Time In:  12:27  Time Out:  13:26    Time:   :59

Dive Location: Sharks Cove,  Oahu, HI.

Dive Shop:  Island Divers Hawaii – Scofield Barracks

Purpose: DMC – Open Water Dive 3

Dive Type:  Shore       Environ: Ocean / Salt

Conditions:  0-2′ Surf    Wt:  22lbs

Visibility: 30-40′

Air Temp:  81° F  Btm. Temp:  79° F

Max Depth:  27′    Average Depth: 18′

Safety / Decompression Stops: None

Start PSI: 3,091    End PSI: 1,356      Air/EANx:  21%

Exposure Protection: 5-Mil Full Wetsuit, Hood, Boots, Gloves

Equipment: 3cf Spare Air, Dive Light, Scuba Pro Jet Fins

Notes:

For the third dive of the students Open Water Diver course, Open Water Dives we first went to the sandy area at the center of Sharks Cove so that they could perform their required skills, then took a tour of Sharks Cove going over some shallower areas where the rocks from the bottom come up higher. This was done so the students could see how their depth affects their buoyancy and as they come up shallower they have to release more air from their BCD’s to keep from floating up too fast and surfacing accidentially. Again a couple of the students had some buoyancy issues which I assisted them with.

Since we completed dives 1, 2, & 3 of their Open Water Dives today we only have 1 dive left that they have to complete tomorrow. The forecast is that the waves will be a little higher tomorrow, so hopefully this will allow us to get it over with before it gets too bad for them.

For the second dive of the students Open Water Diver course, Open Water Dives we went to the sandy area at the center of Sharks Cove so that they could perform their required skills.

A couple of the students had some buoyancy issues and other problems which I assisted them with so that it didn’t cause a problem or turn into an emergency situation.

After the students had finished performing their required skills we ascended so that we could take a long surface interval before continuing with their third dive of the day.

Notes:

As part of my Dive Master course I have to assist an instructor (Michelle) with teaching several classes, one of which is the Open Water Diver course that we started back on May 6th. The conditions finally cooperated with us and we got to do the Open Water Dives for this class today.

The visibility wasn’t the best in the world today at Sharks Cove, but it was the only dive spot on the island available because of the high surf caused by the South Swell that is hitting the island this weekend. There were at least 4 classes going on from Island Divers Hawaii, and more classes from at least 4 other dive shops on Oahu all at Sharks Cove today. I have never seen so many divers all at one spot before, very tricky trying to walk up and down the hill from all the foot traffic today.

For the first dive we went to the left side of Sharks Cove where it was shallower and found a nice sandy bottom area for the students to perform their required skills. Since it had been so long since they were in the water performing the skills (May 10), some of them had trouble remembering the skills so we had to work with them a little more to refresh their memory.

Everyone was finally able to complete their required skills so we ascended to take a surface interval before the next dive.

“Follow the Leader”

Product Review – Oceanic Excursion 2

Up until now I have been using the Oceanic OceanPro 1000D which is a jacket style BCD, primarily because it was on sale as a package at the local dive shop when I signed up for my Open Water certification however I have never really been happy with it.

The OceanPro 1000D did not fit me very well at all because I am in-between Large and Extra Large sizes. I assumed that I would be able to use the adjustable straps to make it fit better, however this turned out not to be the case. It always flopped around on me underwater and I had to constantly adjust it throughout the dive, so it was time for a change.

I checked into more expensive back plate style BCD’s that the other instructors were using, but I just could not afford to invest that much money into something that I had no experience with to know if it would work better for me or not. I finally decided on the Excursion 2, back inflate BCD from Oceanic which I was able to try on at Island Divers Hawaii’s brand new Scofield Barracks location and it fit me like a glove.

The Excursion is a back inflate which took some getting used to instead of inflating around my sides, but I found this actually more comfortable. When the BCD is fully inflated on the surface it does not feel like it is squeezing or suffocating me. On the first dive using the Excursion 2, my trim and buoyancy drastically improved and I was able to loose 4 pounds of my weights immediately.

I have been using the Excursion 2 for a week now and I absolutely love it. It has plenty of “D” rings positioned down both sides between the bladder and the vest, as well as more above and below the side pockets and on both shoulder straps. These are not the cheap plastic “D” rings that were on the OceanPro 1000D, these are sturdy stainless steel and are actually meant to be used instead of just being for looks.

The Excursion 2 also has mounting grommets on the side pockets to attach a Spinner Knife and two built-in trim weight pockets on the tank strap.

Because of my past experiences and fears, I always dive with a 3 cubic foot Spare Air alternate air source which can be difficult to mount to a jacket style BCD, but with the Excursion 2, I can mount it on the “D” rings going down the side and it tucks nicely right behind and under my arm, I don’t even notice that it’s there and have to reach back every once in a while to make sure it’s still with me. It feels so comfortable there and does not affect my trim at all. It is almost like it was meant to be attached to this BCD in that location.

With the Excursion 2 BCD I now have the option of diving with a single tank mounted onto my back, or side mounted tanks with the built-in “D” rings on the sides if I decide to pursue that PADI specialty. Unfortunately I have not been able to locate an instructor in Hawaii that offers that course as of yet, but I am still looking.

Overall, for the price, I think this is one of the best equipment upgrade decisions I have made. I love the new Excursion 2 from Oceanic.
