Jill Heinerth Rebreather Seminar at Beneath the Sea

Upcoming Seminar at BTS I still have a few spots left in the Rebreather Fundamentals Workshop with Rebreather Pro Jill Heinerth - Sunday March 25 from 9am - 4pm at the Beneath the Sea Diving Symposium.

Meadowlands Exposition Center, Seacaucus New Jersey Classroom session: $95 will include many educational resources to take home. Tickets available online at: www.BeneathTheSea.org (space is limited) Enjoy a full-day academic session with CCR expert Jill Heinerth. Using fascinating stories and a multimedia presentation, Jill will cover all the essentials of rebreather diving.

If you are looking to purchase a rebreather, this is an opportunity to learn how to be a wise consumer and make the choice that is right for you. If you already own a rebreather and want a review of academics, new trends and the future of CCR diving, then this seminar will offer an opportunity to gather new information. If you want to prevent yourself from joining the ranks of 20 or so people who perish each year on rebreathers, this workshop will inform you about accident analysis and prevention. If you want a day with an expert who will carefully answer your questions and help you find solutions, then this is your best opportunity to spend a day with Jill. If you want to see how rebreathers are being used in exciting expeditions around the world, this full-day road show will entertain and motivate you to participate in CCR diving.

The workshop is non-denominational… all training agencies and all manufacturers are welcome. All levels of divers are welcome from recreational through technical divers.

Topics: Rebreather operations and procedures Basics, types, operation and essential care Selecting a rebreather: comparing apples and oranges Selecting an instructor Understanding CE testing Myths and misconceptions about rebreather diving Carbon dioxide: dangerous and ignored Reducing oxygen issues Planning for the future: deep mixed-gas operations Accident analysis and prevention: beating the complacency trap Traveling with rebreathers: tips and warnings Lots of time for questions...and answers

See you there -- Jill

Tom Iliffe and Jill Heinerth to 448 fsw on CCR

Jill and Tom dove to 448 fsw yesterday during the NOAA Ocean Explorer Bermuda Deep Water Caves project. Jill was on her Sentinel and Dr. Tom dove his trusty Megalodon. These are the deepest dives ever conducted off Bermuda. Here's quick pic of the sea bottom at 448. More to come.

Video: Critical Rebreather Pre Dive Checks by Paul Heinerth, Brian Kakuk and Jill Heinerth on NOAA Research Mission

This is a good little sample video shot and edited by Nic Alvarado. It gives a sneak peek into our pre-dive regimen on the Bermuda Deep Water Caves Project. We all use checklists to prepare our rebreathers as well as signed gas logs for every tank. Each diver must also have a witness for critical points in their pre-dive check such as inserting a fully packed canister into the rebreather. On the boat, prior to leaving the dock, we go through a group check where each diver touches and verifies that their tanks are onboard, personally analyzed and checked in the gas log. Check lists are cool and they save lives.  -- Jill Heinerth

Rebreather Diving Consumables

I get asked about the cost of consumables for rebreathers quite often. Here is a breakdown based on an average rebreather. Many variables exist for particular units and tank sizes.

Oxygen - in North Florida a tank is filled for about $4 - $6 and lasts up to ten hours, independent of depth
Diluent - depth dependent, but lasts for a good day of diving for $4
Bailout - these are likely plumbed to your inflator and/or dry suit, but won’t be used for anything beyond safety checks, practice or open circuit bailout, therefore will last up to months prior to refilling unless you have had an incident
Batteries - depends on your unit. Mine is rechargeable, so extremely low cost. My first rig had batteries that were $100 for about 40 hours of use!
Sorb - averages between $25 and $30 per fill or cartridge for most people. These may last from two to six hours depending on your unit, although it is always advisable to start fresh for deep.
Trimix - local prices vary dramatically, but you will likely only need 13 cft (2 liters) of mix for a deep dive. If you keep a filled pair of bailout tanks, you’ll only be refilling the onboard tank for dives. It is cheaper to store an extra set of bailout tanks than fill and dump on a regular basis.
Service - don’t forget to factor service into your life. Don’t wait for something to break. Be proactive.  Jill Heinerth

Rebreather Presentation Pt.6 Diluent Gases - Jill Heinerth

Extreme Cave Diving DVD

  Extreme Cave Diving DVD now available in our online store at www.JillsDiveShop.com

This is the recent expedition to Bahamas Blue Holes with Dr. Kenny Broad, Wes Skiles, Brian Kakuk and Jill Heinerth. Stunning underwater footage! Even a bit of rebreather controversy stirred up in the silt. Plenty of rebreather footage, as Jill, Brian and Kenny push CCR technology to the limit.

Buy it today and own a copy of one of the most beautifully filmed expeditions to earth's most dangerous frontier!

New Oxygen Connection to Meg Head

Recent Megalodon models have been shipping with a screw fitting to the oxygen injection in the head rather than a quick connect fitting. In both cases, it is extremely important that this fitting is kept clean prior to connection. Anything in the opening of the hose or on the quick connect can be forced into the solenoid valve. Salt water over time can cause corrosion of interior parts. Blow a little gas through the fitting before connecting.
The threaded hose is a very secure connection, however, it is a little inconvenient in the prep process. You may not be ready to connect to the head, but you have an open LP hose. Purchase a small slider valve to protect the hose end when it is not attached to the head. Leave it in the off position. Now you are able to check tank pressure if you need to. Use the slider as a bleed valve to depressurize the line. Then unscrew before hooking up to the head. Think of it as a cap for the hose, keeping it clean.
I’m not a fan of sliders that are used to disable oxygen supply to the solenoid. I think they leave room for mistakes. I prefer feathering the tank valve on and off in the event of a high PO2 failure.
