Sergeant Major, Lanai Hawaii (Steven W Smeltzer)

Sergeant Major Overview

As you descend from the boat you will notice a couple of small arches which you can swim through.  You will see a large number of Starfishes and also nudibranchs.  As you are swimming over the hard corals, make sure you look closely.   You can also find Commerson Sergeant Major, Lanai Hawaii (Steven W Smeltzer)Frogfish and a variety of endemic fish, such as the Regal Parrotfish.  I have seen a Commerson Frogfish several times not too far from the first small archway that you will probably swim through on the center lava ridge.   These fish are very difficult to spot as they tend to blend in with their surroundings so Sergeant Major, Lanai Hawaii (Steven W Smeltzer)make sure you keep your eyes open.

The visibility here is usually good to very good depending upon the currents.  The depth on the site is up to about 50 feet making it perfect for a second dive.  The site has three parallel lava ridges running perpendicular to the shoreline with a sand channel offSergeant Major, Lanai Hawaii (Steven W Smeltzer) to the west.  The center lava ridge or finger has two swim throughs that are fairly narrow  and a high number of hiding places for various and habitat for a wide variety of marine species.

Current can be an issue here at times, so listen carefully at your dive briefing and to your boat captains instructions as you get ready to enter the water.  You will sometimes find pods of dolphin in the area, or sharks but they are fairly rare.

As in all dives I recommend going slowly and take time to appreciate the site. Read other dive site reviews on my blog and see other underwater photographs on my website and follow me on Twitter @ images2inspire. The pool is open…
