Skimmins Reef – Oahu’s Rarely-Visited East Side Drift Dives with Island Divers

When we get breaks in the winter weather, Island Divers is perfectly positioned minutes away from the doorstep to the long reef wall surrounding Hanauma Bay, which spans from the tip of Portlock Point (sometimes known as “China Walls”) all the way to Lanai Lookout. With Spitting Cave, Sea Cave, Baboon Nose, Palea Point, Skimmins Reef, Marioworld, and Lanai Lookout dive sites all in your back yard and variable winds on the forecast, you know where we’re going…

Bespoke Scuba Lessons

Bespoke Scuba Lessons

If you are looking for normal semi private 2 day scuba lesson, this is not the right page.  Go here.

Bespoke scuba lessons are available for anyone willing to invest in their new hobby by purchasing equipment.  However, if you have not yet done your first dive, the process will begin with a pool session and an open-water dive.  Executive-level private try dive instruction is $500.  Further training costs are reduced by this amount.

the kinds of people bespoke scuba diving lessons graduates meetCost of Bespoke Scuba Lessons

$1500 plus $750 per extra person in your private group.  Too much? Follow this link for no-purchase training starting at $595.  Bespoke lessons with 5 boat charters and private training are actually less expensive than retail. You are leveraging your equipment purchase with us.

Each client will purchase, at MSRP, a full set of scuba equipment with a minimum value of $3000.  This is not hard to achieve with a quality equipment purchase.  You will be advised in that purchase by your private instructor who will guide your purchases to fit the kind of diver you intend to be.  All set up of the equipment, and training in its use will be an integral part of your growth as a diver.  Scubapro, Aqualung, Oceanic, Mares, and Garmin, are some of the brands we deal with.

What is included in bespoke scuba lessons?

  • all private instruction
  • as much pool time as needed – your pool or ours
  • training in the use of YOUR new equipment
  • up to 5 boat charters – 10 dives (only 2 charters are required, the rest is our investment in your development)
  • Nitrox training (every diver should have this)

Who will be my private scuba instructor?

You may choose your staff member if you have met someone you admire.  Otherwise, our general manager will speak with you about your needs and we will assign one of our most experienced instructors.  Of course, you may change instructors if you wish.  It does not escape our notice that clients that are requesting this service are excellent customers, we will put you with our best, and OUR best are pretty awesome because they are all great.  If you would like to be trained by the owner, Dr. Matthew Zimmerman, it will need to be coordinated with the international dive trip schedule.

What will the schedule look like?

That is really up to you withing the constraints of the requirements.  Your private instructor is a working professional so you will need to be respectful of their time and not cancel last minute on them (reasonable emergencies excepted), but basically, you can decide on the schedule. Once and instructor is assigned and you have an idea of time required, the two of you can make a bespoke schedule.

You will have your private instructor on the water with you on regularly scheduled boat charters.  Private charters would incur an additional cost ($500 off the $1700 normal rate).  Equipment setup can occur in your home or at the shop (the shop would be better equipped to deal with any adjustments, it is also stocked with accessories you may find that you need/want).  The pool is yours or ours, whenever is convenient for you.  Your instructor is available for up to 5 2 tank boat charters and unlimited pool time.  Boats depart twice daily 7 days a week, so scheduling those is not an issue.

What certifications will I earn with bespoke scuba lessons?

Lifetime Open Water Certification is the primary certification you will earn.  If you have that already we will advance your ratings from where you are currently.

You will also earn a Nitrox certification.  Next, we will be spending a lot of time on buoyancy control. Enough to earn the Perfect Buoyancy rating as well.  Part of the dive education you will receive includes the difference between the two types of Advanced ratings. You will earn one or be on the way to the other, your choice.  Earn additional ratings at a small cost.

What’s next?

Many people come to us with a trip somewhere already booked and they want to dive when they get there.  Bespoke scuba lessons training will prepare you for that.

If you want personalized travel advice related to scuba diving we will put you in touch with the owner, Matthew Zimmerman, who runs the international dive travel program.  You can just get advice on where to go, or you can join a group trip.

Get started!

Send an email to info@islanddivershawaii.com and mention you are interested in bespoke scuba lessons.  That will start the private instruction and guided equipment purchase process.

The 2021 Grand Prize for Master Diver2021 Master Diver Challenge Grand Prize

group photo from 2007 Egypt dive tripThe Grand Prize is a liveaboard trip for 2 people to the Red Sea on an Aggressor liveaboard.  Can be completed anytime in 2022.  The prize has a value of $5400.  That is pretty amazing.  Island Divers did a liveaboard trip to the Red Sea in 2007.  The diving was fantastic and we added on a week to go explore the antiquities of Egypt.  We used another operator but I know that Aggressor can arrange this extra week as well.  It was a combination of the upper Nile temples and tombs and Cairo for the pyramids.  The upper Nile was our favorite.  Karnak temple being the highlight in our opinion.

 

Here is a high quality link Red Sea Master Diver Challenge for 2021 to the prize description.

 

 

2021 prize for earning Advanced Open Water2021 Master Diver Challenge Prize for Advanced Open Water

The prize for earning you Advanced Open Water in 2021 is a single space at the Blue Angel dive resort in Cozumel.  It is based on dbl occupancy, so you’ll need to bring a buddy or pay for a single supplement, but it is still a great prize.  Island Divers Hawaii Dive Travel plans a trip here every couple of years.  Here is a past example.

2021 Master Diver Challenge Prize for Specialty Diver

2021 prize for earning Specialty Diver

The prize for earning your Specialty Diver rating is 4 days of diving and 5 nights hotel at the Looe Key Reef Resort in Florida.  Also based on double occupancy.  What is great about this prize is that almost everyone can enter to win.  Without even coming to Hawaii you could book a Nitrox Course and a Marine Ecology course, have logged at least 12 dives, and SSI will issue you a free Specialty Diver rating and automatically enter you to win.  That is pretty amazing.  We can set this courses up for you at anytime, from anywhere, just give us a call.

I love it, how can I get started?

Easy.  Keep logging your dives in the free MySSI app.  SSI regularly updates your profile with courses and dives and automatically applies your free earned ratings and enters you to win.  Prizes are awarded in January of 2022 after everyone that earned the rating that year is entered.  So all you need to do is start earning those specialty certifications.  If you are visiting Oahu and booking dives with us, the easiest to add on is Nitrox for $125.  That is the world’s most popular specialty and a good one to have.  Nitrox does not require dives, so you can actually do it remotely. However, most people want to dive the gas during the course.  Another easy way is to add on a fully online Ecology course, like the Marine Ecology course we have planned for March 20th.   For dive club members, probably the best way is to join one of are Group Continuing Education courses that happen all year long on weekends.


 

 

How the SSI Master Diver program works

How to achieve the Master Diver rating with SSISSI Master Diver challenge details

As Island Divers Hawaii shifts its training focus from PADI courses to SSI, one common questions is how does this affect my progress towards the Master Diver rating.  SSI calls this rating Master Diver and PADI calls it Master Scuba Diver.  They are very similar ratings.  However, the SSI rating has some pretty large advantages..

To achieve the Master Diver rating with SSI you need to

  • Log 50 dives
    • These dives need to be logged in the MySSI app.  Since not all divers are habitual dive loggers, this is the minor disadvantage mentioned earlier.  If you have been logging elsewhere, there is a shortcut that a dive center can help you with.  As an SSI dive center, we can access your SSI diver profile and manually change the number of logged dives in the system for you.  We’d are happy to do this for our divers that have logged dives elsewhere.
  • Complete the Stress and Rescue specialty
    • SSI treats the Rescue course as a specialty course.  There is no need to achieve the Advanced Open Water rating prior to starting the course.
    • A prerequisite for stress and rescue is React Right or an equivalent CPR First Aid certification
  • Complete 4 more Specialty courses
    • There is an extensive list of specialty courses available.  Interestingly with the SSI program, none of them have to be specialty courses that include diving.  Meaning that a diver that is interested in pursuing the Master Diver certification with SSI can complete many of the course requirements from the comfort of their home.  This includes Nitrox
    • We recommend that one of these specialty certifications be the online nitrox course.  Nitrox certification allows you to dive nitrox.  While all the specialty certifications are going to expand your knowledge base, there are only a few that are required for a certain type of diving.  Diving with nitrox is one of those that will require certification.
    • Currently, almost all our specialty courses are $125 without dives.  So, for ecology programs and the like that do not require diving, that is the final cost.  Most other specialties can be completed with one set of boat dives.  Again, if you are reading this from somewhere with no local diving, you can complete your online learning in advance and just schedule your dives when you are able to come to Hawaii.

Once these are completed, SSI will automatically recognize you with the Master Diver rating.  Meaning, once your instructor certifies your last specialty in the SSI system and you have 50 dives you will be automatically awarded the Master Diver Rating.  There is no $50+ application fee.  The fee that PADI charges for this is one of the reasons we believe the SSI system is better.

It is worth noting that along the way to Master Diver in the SSI system, you will also get the Level II Specialty Diver* rating and teh Level III Advanced Open Water Diver** rating for free.  Achieving each of these ratings is automatic upon getting the specialities and logging the dives and you also get entered to win dive trip prizes.

*12 dives logged and 2 Specialties  ** 24 dives logged and 4 Specialties

What do you get with the SSI Master Diver rating?

Entry into a yearly drawing for a liveaboard dive trip for 2 people.  Each year SSI takes all the people that achieved the SSI Master Diver rating and puts them into a drawing.  In early 2020 the winner for the 2019 Master Diver Challenge was announced.  Nate Kilgore is the lucky winner in the picture on the right.  He won a liveaboard trip for two on the Belize Aggressor.  In 2020 the winner will got a liveaboard trip for 2 on a liveaboard trip to Honduras.  Here are the 2021 prizes.

Master Diver rating is Level 4 diver in the SSI recognition path, Level 5 diver is the next recognition level with 100 dives.  The SSI Master Diver level is primarily a personal achievement.  It is also the goal of our dive centers to encourage people to shoot for this goal.  We have been doing this a long time.  Many people come out of their certification course and just stall, not sure what to do next.  We like Master Diver as a goal because it includes training that is going to help you be a better diver and be able to better assist dive buddies (Stress and Rescue).  Also, if you make the 50 dives logged goal you really gone from being certified to being a true diver.  For many of us that work here, this has been our primary hobby and source of friends and adventures for years.  It is a worthwhile goal.

If I’m currently holding PADI certifications, how can I switch?

SSI is pretty generous in this regard.  Your initial certification can be with ANY training agency.  SSI lets you count any two specialty courses with any other training agency towards the Master Diver rating.  Stress and Rescue and 2 other SSI Specialty courses must be part of your profile.

If you have specialty courses from another training agency SSI allows us to verify those certifications in the SSI app.  Let us know if you need this.  We will need photocopies of the card.  Big bonus for doing this is that your card will go into your SSI diver profile and be available for free for life!  Just like all of your SSI cards.

Remember, that as the dive center we call manually adjust your number of dives if you are not yet using the dive log on the MySSI App.

 

Who wants to be an ASTRONAUT? rEvo ‘TRY DIVES’ now available at IDH

Dive the rEvo III hCCR… the most advanced diving system on the planet!

 

The rEvo hCCR(hybrid closed circuit rebreather) is the most advanced cutting edge, diving system available for underwater exploration. It rivals the astronaut’s primary life support system and shares much of the same technology. The rEvo hCCR recirculates and conditions the onboard gas supply, extending dive times far beyond those of traditional scuba divers. In addition, there are no bubbles and noise associated with open circuit scuba.

Learn how  rebreathers work and how rEvo divers can remain underwater longer. Discover how they enable divers to closely approach marine life to interact, to take photographs and video, stay warmer and make observations that would otherwise be missed by divers on open circuit scuba. Once you’ve gone Silent, you’ll hear what you’ve been missing!

 

CCR Try Dives at IDH

There are a few options available for divers wishing to ‘try before they buy’ and we always encourage you to get all the information possible before making a commitment to buy a CCR.

As a diver you have the following options available but if you feel your needs are not met below then please drop us an email detailing your specific request as we tailor events to suit your needs.

Option 1 is an informal 1-2 hour conversation. There is no charge for this but it must be pre-booked and arranged so please don’t show up expecting someone to be available. Drop us an email with the timescale that suits you best and we will advise you when it is best to arrive.

Option 2 is a more detailed version of the above costing $150.00+tax for half a day. With Option 2 we spend more time going into details of the available units plus fire them up and you get to ‘try dive’ them in our pool.

Option 3 is the same as option 2 but with an afternoon out on one of our boats. Please note that with option 3 we do charge an additional boat fee of $60.00 for a total cost of $210.00 per person+tax.

We would like to point out that our rEvo Try Dive days are very different than what is currently available on island. If you’re looking for a quick 20 minute dive on a CCR then there are other instructors offering this option. We consider ourselves a little more organised and professional which is why we meet and greet you in our shop before moving on to the in-water portions of the experience. All fees are included in the prices quoted above and there are no hidden extras involved. We make the theory part of the day informative and enjoyable with plenty of time to play with the units and ask questions.

What are you waiting for? Come on down to IDH and play with our units.

rEvo REBREATHERS
The rEvo rebreather is the brainchild of Paul Raymaekers, and is available in a number of configurations, which include different models, different electronics packages, and different case materials. Here we will try to make the explanation of the units as clear as possible.

rEvo I, rEvo II and rEvo III

The rEvo I was the original prototype units that were made to ‘work the kinks out’ when the rEvo was still in development. The rEvo II was the first production unit, and has also since been discontinued. While the II is no longer available, hundreds of them are out in the market being active dove, and many appear for sale in the secondhand market.

The rEvo III was designed and released to meet CE specifications, and today the only units for sale new, are rEvo III. The rEvo III is available in several different versions, in which the main differences are size and weight.

CO2 Scrubbing

All rEvo rebreathers come standard with back mounted counter-lungs, and dual 3 pound scrubber cassettes. These scrubbers are used in series, and increase the safety margin, reducing the risk of channeling and bypass.

As an option the RMS system allows for monitoring of your scrubber capacity, and provides a real-time estimate of how much time you have remaining.

For ultra-long dives, an optional radial scrubber system brings the absorbent capacity up to 8.8 lbs of absorbent.

PO2 Monitoring

The rEvodream is the standard PO2 monitoring device and head’s up display which comes on every rEvo unit. It can monitor your choice of one or 2 oxygen cells.

PO2 is displayed on a digital display which mounts to the submersible pressure gauge. The revodream will also display a range of PO2’s using a simple 3-LED display which clips to the DSV of the rEvo, always in view of the diver’s peripheral vision.

The rEvodream has no switches, and is operated by using a series of taps which actuates an internal accelerometer. Powered by standard CR2450 coin batteries, this simple design makes the rEvodream a very robust and reliable solution.

Each rEvo is sold with 2 PO2 monitoring devices, which includes 1 rEvodream PO2 monitor and HUD, and your choice of the following:
rEvodream PO2 monitor and HUD
Shearwater Predator trimix computer and PO2 monitor (hardwired)
Shearwater Predator trimix computer and PO2 monitor (Fischer cable version)
Shearwater Predator trimix computer and setpoint controller (hardwired)
Shearwater Predator trimix computer with RMS setpoint controller (hardwired Digital CAN bus)

Manual Gas Addition

Manual gas addition can be done in one of 2 ways, either through manual addition buttons found on the bottom of the rEvo case, or through a 3-gas addition block.

The 3-gas addition block hangs over the diver’s chest, and allows for ambidextrous addition of either diluent, oxygen or an offboard gas to be plumbed in through the lower quick-disconnect. The 3-gas block comes standard with the rEvo III Micro FT, and is an option on the rEvo III Mini and Standard models.

The case mounted manual addition buttons are found on the bottom of the rEvo III Mini and Standard models. These can be removed as an option. The rEvo III Micro FT does not have these buttons on it, and they cannot be installed as an option.

Automatic Oxygen Addition

Gas can be automatically added to the loop by either a constant flow orifice, and absolute pressure oxygen 1st stage. As the diver increases in depth, the absolute pressure regulator reduces the flow.

In addition, an optional solenoid via a Shearwater Predator controller may be added, providing automatic setpoint control in addition to the constant flow. Utilizing both a solenoid and constant flow creates a ‘hybrid’

On hybrid models, the constant flow orifice can be plugged, and the absolute pressure regulator may be replaced with a standard compensating regulator to allow for true eCCR operation.
