Reviewer: david s.
Been Diving with a 17 year old parts anymore so had to purchase a New Reg....did a lot of shopping..comparing...Dive shops tried to sell me all brands and high end cold water regs. I dive warm water non-technical all over the world. Decided on the Aqua Lung Titan LX. Did my first dive trip with it in Grand Cayman (It was an almost Free vacation) Reg worked Great! I like the fact the boat crew cant blow water into first stage :) SCUBA Com was fast and good price. Recommend for warm water diving!

  • joan:

    Id like to purchase an aqualung regulator from When and if I need warranty work done on the regulator, how does that work? Would I send it back to the manufacturer, or to or can I take it to my nearest dealer?

    Arthur  (Certified Scuba Instructor at

    Good morning, The Free Parts for Life Program allows the customer to receive free parts when the regulator is due for overhaul. Free parts consist of the normal replacement items as found in the Regulator 1st & 2nd Stage Service Kits. Labor charges are not covered. Assuming the program guidelines are followed, the Free Parts for Life Program will apply to the life of the regulator and will significantly reduce the cost of ownership. This program is in addition to the standard product warranties outlined in the owner’s manual. The Free Parts for Life Program is a commitment by you (the Regulator owner), your Aqua Lung Dealer and Aqua Lung. To participate, you must be the original owner and have purchased the regulator from an Authorized Aqua Lung or Apeks America Dealer. The regulator must be brought to an Authorized Dealer at least once a year for inspection or overhaul according to the below schedule: Year #1: Inspection Year #2: Overhaul Year #3: Inspection Year #4: Overhaul Etc. To keep the Free Parts for Life Program active, both inspections and overhauls need to be documented in the Annual Service & Inspection Records included in the Owner’s Manual CD or can be found online here. If an inspection or overhaul is missed, the regulator no longer qualifies for the Free Parts for Life program.

  • Joan:

    As far as warranties are concerned, Is a registered dealer with Aqualung and not a grey market dealer?

    Darrick  (Certified Scuba Instructor at

    Hello Joan, we are an authorized dealer for all of the gear we carry. But to find out if a place is an authorized dealer all you would have to do is call the manufacture directly and they would let you know who is authorized dealer or gray market dealer.

  • Jordan:

    Hi, I have an older Titan LX and Im looking to replace the 1st stage, if possible. Id like to find out if I can just order a first stage with 2 HP ports like the newer one has. Is there a way to just order the 1st stage? If so, what would be the cost? Alternatively, Ive looked for an HP splitter but those are very hard to find and Im not sure if it is a good/safe solution.

    Darrick  (Certified Scuba Instructor at

    Hello Jordan, this would be a special order item. You would need to call us at 1.800.347.2822 for the pricing and lead time on the 1st stage you are looking for.

The ever-popular Titan LX is not only light weight and travel friendly, it comes standard with Aqua Lung’s auto-closure device (ACD) . The ease of breathing is rated superior on the ANSTI breathing machine. All this, along with an attractive mid-range price, makes the Titan LX a sure value.

The auto-closure device (ACD) keeps corrosive water out of the first stage thereby ensuring top performance

The balanced diaphragm first stage, by the nature of its design, is environmentally sealed and provides superior, consistent performance from beginning of dive to end of dive

A pneumatically-balanced second stage results in superior ease-of-breathing

Available in yoke (3300 psi / 232 bar max) or din (4350 psi / 300 bar max)

The T-shape of the first stage optimizes the location of the 4 MP ports and 1 HP port

Lighter weight makes it a great travel companion

Uses parts that are common to other Aqua Lung models for easier servicing

The easy-to-grip venturi lever prevents unwanted freeflow at the surface while giving a performance boost at depth

Compatible with nitrox, up to 40% O2, new out of the box

Equipped with Aqua Lung’s patented Comfo-bite mouthpiece along with a reusable mouthpiece clamp

The Supreme cold water version is resistant to freezing when diving in waters colder than 50°F / 10°C

Available for shipment to U.S. zip codes only
