Authorized Poseidon™ Dealers are general dive equipment retail partners with access to purchase the Poseidon recreational SCUBA product range at wholesale pricing, and who agree to always adhere to our business policies and practices. Assuming your retail dive business is located in the US or Caribbean and meet the criteria, we will help establish your dealership with Poseidon Diving Logistics. To apply to become an Authorized Poseidon Dealer, just complete our Dealer Application to tell us about your shop and your team.

The Poseidon.com website maintains resource locator page at https://www.poseidon.com/en-US/dealer-locator that lists all our Flagship dealers, On-line retailers, and Service Centers. Standard Poseidon dealers in the US may no longer be listed on the locator page, contact our sales team to start a discussion on how your enterprise can be listed on the Poseidon resource locator page.

Because Poseidon Diving Logistics LLC is located in Florida, for goods and services delivered within the State of Florida we incur special record keeping requirements related to B2B transactions that do not collect and remit our state sales tax.

• The business or organization must be registered with the Florida Department of State - Division of Corporations at Sunbiz.org records.
• The business must provide us with a copy of their current DR-13 Florida Annual Resale Certificate for Sales Tax or in the case of organizations a DR-14 Florida Consumer’s Certificate of Exemption, issued by the Florida Department of Revenue.
• The business name and address on the unexpired certificate must match the bill-to name and address on our sales invoice.

Florida law also grants state, county, and municipal governmental entities an exemption from Florida sales and use tax. To be eligible for the exemption, Florida law requires they provide a DR-14 Consumer’s Certificate of Exemption. However, the United States federal government and any of its federal agencies (such as Navy, NOAA, Coast Guard, NASA and NPS) are not required to provide a DR-14.

PAID shipping orders that are in-stock typically dispatch within one business day. See the map above for typical ground transit times in business days for your location. Faster transit times are available using expedited service options. International shipping is typically less than a week to the Caribbean.

FREE shipping delivery times are typically one to two weeks for the US and up to one month for the Caribbean. However, please select a PAID shipping choice if your order is time-sensitive, requires door-to-door tracking during transit, or to choose a specific carrier service level.

The short answer is yes for most countries and territories in the Caribbean Sea and Poseidon Diving Logistics LLC guarantees safe arrival of your order. Orders shipped outside the US are subject to local import fees collected by the courier upon delivery.

For other countries and territories in the Americas that are not currently served by an Authorized Poseidon Distributor we may be able to ship to established local dive retailers with approval from Poseidon Diving Systems HQ.

The official Poseidon Diving Systems factory warranty period in effect worldwide for decades continues to be 24 months. Products purchased through an Authorized Dealer of Poseidon Diving Logistics are supported with our enhanced US Limited Warranty that varies by type of product. Effective 2025, Poseidon Diving Systems branded products purchased in the US are now guaranteed for the useful life of the product. See US Limited Warranty for details.

The goal of Poseidon Diving Logistics LLC is to maintain stock in the US for all Poseidon brand service kits and field replaceable parts that have been ordered within at least the previous two years. This should offer immediate availability of parts for all current consumer products and most commonly requested parts for older equipment. Very rarely requested parts, or parts for obsolete products with limited availability, may be backordered from Sweden with approximately 30-day availability (ARO). Unfortunately, there are a few very old and long discontinued Poseidon products for which some parts are no longer available (NLA) or for which service is not cost effective.

Any authorized Poseidon Flagship Dealer or Service Center can provide warranty, repair, and maintenance for Poseidon equipment. We can also recommend a qualified service provider in your area if needed.

Poseidon also operates a dedicated service depot in the United States to provide consistent, expert repair and maintenance service regardless of location. Simply ship Poseidon brand equipment to the depot, then get it back fully serviced and ready to dive. To get started or learn more, please contact Poseidon Diving Logistics.

Periodic service by a certified Poseidon Service Technician, as specified in the product manual, is recommended to maintain the US Limited Warranty and ensure optimal performance. Poseidon supports right-to-repair, and the use of third-party service or non-OEM parts does not, by itself, void the warranty. Poseidon Diving Logistics does not restrict their Authorized Dealers from retail sale of parts to individuals nor do they restrict access to maintenance manuals.

However, availability of service kits, replacement parts, specialized tools and maintenance manuals does not imply qualification to assemble and/or service Poseidon Diving Systems equipment. Improper service of diving equipment can result in serious injury or death. Poseidon recommends that divers participating in more advanced technical and exploration type diving be trained in equipment service. We recommend that non-qualified individuals seek professional training/mentoring before attempting repairs or servicing on any diving equipment.

Authorized Poseidon™ Service Centers are specialized partners authorized to service Poseidon products and handle warranty issues according to Poseidon’s guidelines. These centers have a designated individual certified within the last 36 months as a service technician on Poseidon products and benefit from access to Poseidon equipment service kits and parts.

Service technician training courses are available remotely on-line via video conference or on-site in-person classroom format. Upon successful completion of training the certification as a Poseidon Service Technician is valid for three years (36 months). Visit Poseidon Service Technician Training for details.

Poseidon Diving Logistics does not restrict their Authorized Dealers from retail sale of parts to individuals nor do they restrict access to maintenance manuals. Manuals are available on their website at https://www.poseidondiving.us/manuals

Availability of sub-assemblies and components, repair parts, specialized tools and maintenance manuals does not imply qualification to assemble and/or service Poseidon Diving Systems equipment. Improper service of diving equipment can result in serious injury or death.

Yes and no—this simple question has a complex answer because there is no widely recognized U.S. scuba diving standard defining suitability for oxygen service. From the point of view of stringent U.S. aerospace guidelines and Compressed Gas Association handling standards for oxygen, nothing in general use in recreational diving is suitable for oxygen service. For safety and liability reasons in the US, Poseidon Diving Logistics considers all Poseidon regulators manufactured since 2015 to be Nitrox Ready from the factory, meaning their design and materials (including o-rings & lubricants) are oxygen compatible and clean for use with compressed breathing gases containing a maximum of 40% oxygen.

In terms of cleanliness and compatibility with oxygen, there is no difference between "Nitrox Ready" and "Oxygen Service" prior to initial use. Nonetheless, the 'clean state' of the equipment applies only prior to initial use. Thereafter, periodic inspection and cleaning are a necessity. Divers must meticulously follow the recommendations of the US Department of Transportation (DOT), Compressed Gas Association (CGA), and other federal/state/local agencies, plus their dive training agency for equipment maintenance, handling, storage, labeling, filling, transport and use of compressed gases. Oxygen-related fires and explosions can result in serious injury or death. Ultimately, the diver must make the final decision to assume all risks associated with the use of any compressed gases, including those in excess of 23.5% oxygen.

It's not just that the Duration has green color accents. In the early 2000's, no Poseidon regulator was considered oxygen compatible or oxygen clean from the factory by any standard at that time. When the EN 144-3 "Outlet Connections For Diving Gases Nitrox And Oxygen" standard in the European Union was established in 2003, a unique and incompatible M26x2 connector for oxygen service was required on tank valves and SCUBA regulators. Also at the time, conventional wisdom for diving with oxygen enriched gas mixtures was to substitute oxygen compatible lubricant for silicone grease and to substitute fluorocarbon based elastomers (originally developed by DuPont under the name Viton™) for nitrile o-rings. Those engineering changes were reflected in the Xstream Duration. The Duration M26x2 model of the Xstream was specifically tested and approved for use with pure oxygen, but only in the European Union by their standards.

Eventually the use of nitrox and oxygen became so common that it was more cost effective for dive industry manufacturers to adopt oxygen compatible and clean manufacturing for all their regulators. Also, some concerns regarding characteristics of fluoroelastomers in breathing gas applications began to appear and ethylene-propylene-diene-monomer (EPDM), which is equally oxygen compatible, has become more commonly used. Since 2015, Poseidon now uses oxygen compatible lubricant and oxygen compatible o-rings in all their regulators, including the Deep and Black versions. Some products, like the Duration, that were previously engineered for oxygen service still use Viton o-rings since that was the version that was originally approved for oxygen service.

The Classic and the Xstream first stages paired with an Xstream or Jetstream second stage have an acceptable intermediate pressure range of {109 – 145 psi | 7.5 – 10 bar}, and are set during factory production for {123 psi | 8.5 bar} at {2900 psi | 200 bar} supply pressure. Poseidon’s Xstream and Jetstream second stages require a minimum of {109 psi | 7.5 bar} to seal properly when initially pressurized. If the intermediate pressure exceeds {145 psi | 10 bar}, certain soft components inside the second stage may risk being damaged. Because the Xstream and Jetstream second stages are upstream design, since 2008 the first stages incorporate an OPV that opens if the IP exceeds approximately {200 psi | 14 bar}.

The Classic and the Xstream first stages paired with a Cyklon second stage have an acceptable intermediate pressure range of {145 – 189 psi | 10 – 13 bar}, and are set during factory production for {167 psi | 11.5 bar} at {2900 psi | 200 bar} supply pressure. Because the Cyklon second stage is downstream design, if the IP is too high the second stage will free flow and if the IP is too low the regulator will be difficult to breathe.

For details on Poseidon IP settings & behavior, see TECHNICAL BULLETIN – 2025-06-02.

Routine maintenance as described in the applicable Poseidon product manual is recommended to maintain the US Limited Warranty and ensure optimal performance for all Poseidon products. Poseidon recommends their SCUBA diving regulators used in recreational diving applications receive an annual inspection plus a preventive maintenance service from a certified Poseidon Service Technician at least once every 24 months or 100 dives, whichever comes first. Please keep in mind that the recommendation is based on typical sport diving usage; other types of usage may require more frequent inspection and maintenance. A regulator comprehensive preventive maintenance service includes replacing wear parts using an OEM service kit, cleaning and lubricating, along with testing and adjustment on a flow bench to verify performance.

The widely accepted absolute maximum useful lifespan of all galvanic chemistry oxygen sensors in rebreather applications is 18 months, typically 12 months or less depending on usage and environmental factors. Because oxygen sensors are so critical to the operational safety of Poseidon rebreathers, we recommend discontinuing the use of R-22D type oxygen sensors that have been in-service over 12 months or have a total age over 18 months. The expiration date printed on some sensors is not a guarantee they can remain in-service until that date; it is a caution against use after that date. There is no field test, dive procedure, or calibration that can reliably validate a galvanic oxygen sensor for use beyond its expiration date or recommended service life.

Unlike galvanic chemistry type oxygen sensors, the digital Poseidon Solid State Oxygen Sensor (SSO2) has no need for routine periodic replacement. The useful life of the Poseidon SSO2 is estimated as being at least ten years, possibly much longer.
