What was recalled
In June of 2019, the U.S. Consumer Product Safety Commission (CPSC) announced a significant recall involving specific buoyancy compensation vests manufactured by Mares. These are not general swimming aids or standard pool flotation devices; they are specialized pieces of technical scuba diving equipment designed to help divers control their depth and maintain neutral buoyancy underwater. The recall targets products within Mares’ XR Line, a series known for its durability and performance in more demanding diving conditions. If you are a recreational diver who has used Mares gear, or if you are currently enrolled in advanced certification courses that utilize this specific line of equipment, it is crucial to understand exactly which items are affected by this safety notice.
The core issue lies within the inflation mechanism of these vests. Specifically, the recall covers models equipped with a deflation button that can potentially unscrew itself during use. While the vest may appear functional and intact on the surface, this mechanical failure poses a severe risk underwater. The affected items include several distinct configurations within the XR Line, identified by specific model numbers and descriptions. These include the Donut Bladder Single Tank (Model # 417511), the Donut Bladder Twin Tank (Model # 417512), the Sidemount Pure Light Bladder (Model # 417536), the Red Devil Single Backmount set (Model # 417539), the Red Devil Single Backmount set SSI (Model # 417540), the Pure Light Sidemount compl.set (Model # 417547), the Silver Knight Single BM set (Model # 417550), and the Blue Battle Single Backmount set (Model # 417551). Each of these models represents a different setup configuration, catering to various diving styles such as backmount or sidemount diving.
Identifying whether your specific vest is part of this recall requires checking two key details: the model number and the serial number. The model numbers listed above are printed on the product label. However, even if you have one of these model numbers, you must verify the serial number to confirm inclusion in the recall. The serial number is located on a rectangular label attached to the inflator body of the vest. The recall affects units with serial numbers ranging from 8A-02001 through 8A-07630. This specific range indicates that the manufacturing defect was limited to production batches within this timeframe, rather than affecting all XR Line vests produced by Mares. Consumers who own a vest with a model number in the list above but a serial number outside of this range are not subject to this particular recall action.
These products were sold through authorized Mares scuba dealers across the United States. The recall was officially announced on June 12, 2019. If you purchased your vest recently or second-hand after that date, it is possible it falls within the affected serial number range. Because these are high-value, specialized items often kept in good condition and passed down or sold among diving communities, checking your specific unit’s details is more important than the purchase date alone. The scope of this recall is precise, focusing only on the identified model numbers and serial ranges to ensure that divers with safe, unaffected equipment are not unnecessarily inconvenienced, while those at risk receive immediate attention.
The hazard, explained
When you are underwater, your buoyancy compensation vest (BCD) is not just a piece of gear; it is your primary interface with the environment. It functions as a life-support system that keeps you suspended at a comfortable depth, allowing you to breathe normally and observe the marine world without fighting gravity or sinking uncontrollably. The Mares XR line of vests relies on a precise mechanical link between your breath and the vest’s ability to hold air. Specifically, the deflation button is designed to release excess air from the bladder when you need to descend or equalize pressure. In the recalled units, this critical component has a manufacturing defect where the button can unscrew itself from the inflator body.
This failure is insidious because it often does not happen with a dramatic explosion or sudden collapse. Instead, the button may work intermittently at first, becoming loose over time until it eventually detaches completely. When this happens, the internal seal that holds air within the bladder is compromised. Air escapes rapidly and uncontrollably through the opening left by the missing or loose button. For a diver relying on that trapped air to stay off the bottom, this results in an immediate and total loss of buoyancy. You effectively become as heavy as your equipment, including your tank, regulator, and weights.
The physical consequences of this sudden weight gain are severe. Without positive buoyancy, a diver will sink rapidly toward the seabed or into deep water. This rapid descent can cause barotrauma to the ears and sinuses if the diver cannot equalize fast enough. More critically, it creates an extreme panic-inducing situation where the diver must scramble to inflate their vest manually using their oral inflator while simultaneously trying to maintain airway control and ascend at a safe rate. If the deflation valve remains open or disconnected, no amount of manual inflation may be sufficient to counteract the leak.
The ultimate risk is drowning. Even experienced divers can struggle to manage multiple emergencies at once. If they are pulled down by their own gear while trying to fix a mechanical failure, they may run out of air before reaching the surface. This is why the Consumer Product Safety Commission and Mares have classified this as a drowning hazard. The incident report noting a loose deflator button serves as a warning sign that the mechanism is failing. While no injuries have been reported in this specific batch yet, the potential for tragedy is high because the failure removes the diver’s ability to control their position in the water column.
Who is most at risk
The primary group facing risk in this recall consists of individuals who own and actively use Mares XR series buoyancy compensation vests (BCDs) for scuba diving. Specifically, the hazard targets divers who possess units with serial numbers ranging from 8A-02001 to 8A-07630. This includes a variety of configurations within the XR line, such as the Donut Bladder Single Tank (Model #417511), the Donut Bladder Twin Tank (Model #417512), the Sidemount Pure Light Bladder (Model #417536), and several Red Devil, Pure Light, Silver Knight, and Blue Battle sets. If you are a recreational diver, an instructor, or a professional guide who utilizes any of these specific models for underwater exploration, you are directly in the affected population. The risk is not theoretical; it is tied to the physical mechanism of the vest’s inflation system.
The core vulnerability here stems from the nature of the defect itself: the deflation button can unscrew and detach. In scuba diving, a BCD is your primary tool for controlling depth and maintaining neutral buoyancy. It allows you to ascend safely by adding air or descend by releasing it. When the deflation button fails, you lose the ability to quickly release air from the vest. This creates a critical loss of control over your vertical position in the water. For any diver, regardless of experience level, this is a serious emergency. However, the consequences are particularly severe for those who may already be managing other physical or environmental challenges.
While no specific demographic such as the elderly or children is uniquely targeted by the mechanical failure, the *context* of scuba diving makes certain physiological factors more relevant to safety. Scuba diving requires significant physical exertion and breath control under pressure. A diver who is fatigued, stressed, or dealing with a medical condition that affects breathing or stamina may find it much harder to cope with a sudden loss of buoyancy control. For instance, a diver who cannot quickly deflate their vest might experience rapid, uncontrolled ascent if they are already too buoyant, leading to decompression sickness or lung over-injury injuries. Conversely, if they cannot add air when needed, they may sink uncontrollably. This is why the risk is highest for those who rely on the precise function of this specific component for their safety margin.
Furthermore, divers who operate in challenging environments—such as strong currents, deep wrecks, or overhead limits—are at greater risk because they have less room for error. In these scenarios, a malfunctioning BCD can quickly turn a routine dive into a life-threatening situation. The fact that the defect involves a simple button becoming loose is especially concerning because it suggests a failure that could happen without warning during a dive. There is no gradual degradation that allows for easy detection; the button may simply come off at the worst possible moment. Therefore, all users of these specific models, regardless of their diving frequency or expertise, are equally vulnerable to this specific mechanical failure. The only way to mitigate this risk is to recognize that you own one of these vests and take immediate action to have it repaired before it impacts your safety underwater.
How to tell if you have the recalled item
If you are a scuba diver who owns or has recently purchased a Mares buoyancy compensation vest (BCD), it is important to verify whether your specific gear falls under this recall. Because the issue involves a mechanical failure in the inflation mechanism, visual inspection of the vest’s color or size alone will not tell you if it is affected. Instead, you must rely on two critical pieces of data: the model number and the serial number. The recall specifically targets units from the Mares XR line. To begin your check, locate the rectangular label attached directly to the inflator body of your vest. This label is the primary source of truth for identification.
On this label, you will find a serial number printed clearly. The recall affects products with serial numbers ranging from 8A-02001 through 8A-07630. If your serial number falls within this range, your vest is included in the recall, regardless of its specific configuration. Additionally, you should check the model number printed on the same label or on the product’s original packaging and tags. The following model numbers are confirmed to be part of this safety notice:
- 417511 (Donut Bladder Single Tank - XR Line)
- 417512 (Donut Bladder Twin Tank - XR Line)
- 417536 (Sidemount Pure Light Bladder - XR Line)
- 417539 (Red Devil Single Backmount set - XR Line)
- 417540 (Red Devil Single Backmount set SSI - XR Line)
- 417547 (Pure Light Sidemount compl.set - XR Line)
- 417550 (Silver Knight Single BM set - XR Line)
- 417551 (Blue Battle Single Backmount set - XR Line)
If you have any of these model numbers and your serial number is within the specified range, do not assume the vest is safe to use. The defect involves the deflation button potentially unscrewing itself, which can lead to a sudden loss of buoyancy underwater. If you are unsure about your serial number or cannot locate the label, contact Mares directly using the consumer contact information provided in the recall notice. They can help you verify your specific unit’s status. Until you confirm your vest is not part of this batch, treat it as recalled and refrain from using it for diving activities.
What to do — step by step
If you own one of the recalled Mares buoyancy compensation vests, your immediate priority is personal safety. The very first and most critical step is to stop using the vest entirely. Do not take it on any dives, and do not use it for any water activities where buoyancy control matters. Even if the vest appears to be functioning correctly right now, the defect involves a mechanical failure that can happen without warning. A loose or unscrewed deflation button means you could lose all your air and buoyancy instantly underwater, which poses a serious drowning hazard. Please treat this with urgency and keep the equipment out of reach of anyone who might try to use it. Once you have secured the vest away from active use, you need to verify exactly what you have to ensure it falls within the recall scope. Look for the rectangular label on the inflator body of your vest. This label contains the serial number you need to check against the recall list. The recall affects specific model numbers in the XR Line, including 417511, 417512, 417536, 417539, 417540, 417547, 417550, and 417551. Crucially, the recall applies to serial numbers ranging from 8A-02001 through 8A-07630. If your serial number falls within this range, your vest is definitely part of the recall. The next step is to arrange for a free repair. You should not attempt to fix this issue yourself, as improper handling could compromise the integrity of the inflator mechanism further. Instead, take the recalled buoyancy compensation vest to an authorized Mares scuba dealer. These dealers are equipped to perform the necessary repairs at no cost to you. This is the official remedy provided by the manufacturer, and it ensures that the defect is addressed by professionals who understand the specific design of these vests.

If you have identified that your Mares buoyancy compensation vest is part of this recall, the most important thing to know right now is that you do not need to pay for the fix. The Consumer Product Safety Commission (CPSC) has required Mares to provide a clear and cost-free remedy for everyone affected by this safety issue. Specifically, the company has decided to offer a free repair rather than issuing refunds or sending out entirely new units. This approach is designed to address the specific mechanical failure—the deflation button coming unscrewed—by having trained professionals correct the defect directly on your existing equipment.
The process for getting this repair started is straightforward, but it requires you to take a specific action: you must bring the recalled vest to an authorized Mares scuba dealer. You cannot simply mail it in or attempt to fix it yourself at home, as the recall instructions explicitly state that the repair must be performed by a dealer. This ensures that the technical expertise required to reseat and secure the deflation button is applied correctly, restoring the vest’s safety standards without risking further damage or improper handling of the inflation mechanism.
To find an authorized dealer near you or to get more details on the repair process, you have several reliable ways to contact Mares directly. You can call their consumer support line at 800-874-3236. This service is available between 9 a.m. and 5 p.m. Eastern Time, Monday through Friday. If you prefer written communication, you can send an email to Recall@us.mares.com. For those who like to browse information online first, Mares has dedicated a specific page for this recall at https://www.mares.com/us-US/sports/extended-range/recall/. You can also navigate to the Mares USA main website, hover over “Scuba Diving” in the gray toolbar at the top of the page, and click on “Recall” to access the same information. These channels are monitored by the company specifically for this issue, so they will be able to guide you through the next steps.
It is worth noting why a repair is the chosen remedy in this case. The hazard involves a specific component—the deflation button—rather than a fundamental flaw in the vest’s entire design or bladder integrity. Because the rest of the buoyancy compensation vest remains functional and safe, replacing the whole unit would be an unnecessary waste of resources. Instead, fixing the loose button restores the critical safety function that prevents accidental loss of buoyancy while diving. By taking your vest to a dealer for this free repair, you are ensuring that your gear is back to its original, safe condition without any out-of-pocket expense to you.
While you wait to get your vest repaired, please remember the immediate safety instruction: stop using the recalled buoyancy compensation vests right away. Do not take them on any dives until they have been officially serviced by a Mares dealer. This recall affects serial numbers from 8A-02001 through 8A-07630 across several XR Line models, including the Donut Bladder Single and Twin Tank, Sidemount Pure Light, Red Devil, Silver Knight, and Blue Battle sets. Once you have confirmed your model matches one of these and contacted a dealer, you can rest easy knowing that the fix is free, professional, and readily available.
What can happen if you ignore it
When a recall notice lands in your inbox or appears on a retailer’s website, the natural human response is often one of mild annoyance rather than immediate alarm. It is easy to think, “I will just finish this dive season,” or “It probably won’t happen to me.” However, with the Mares buoyancy compensation vests recalled due to the risk of the deflation button unscrewing itself, ignoring the warning carries consequences that are far more severe than a simple inconvenience. The core issue here is not merely a mechanical failure; it is a catastrophic loss of control in an environment where air and buoyancy are your only lifelines.
The specific hazard identified by the Consumer Product Safety Commission (CPSC) is that the deflation button can come unscrewed, leading to a sudden and unintended loss of buoyancy. In scuba diving, buoyancy compensation vests (BCDs) serve as your primary tool for maintaining neutral depth. If the button detaches, air escapes rapidly from the vest. This does not happen gradually; it happens instantly. For a diver at depth, this rapid deflation causes an uncontrolled ascent. The physics of diving dictate that as you rise, the air in your lungs and any remaining air in your gear expands. Without the ability to manage your buoyancy effectively, you may shoot toward the surface too quickly.
An uncontrolled ascent is one of the most dangerous scenarios in recreational diving. It can lead to decompression sickness, commonly known as “the bends,” which occurs when dissolved nitrogen forms bubbles in your bloodstream and tissues due to rising pressure too fast. More immediately, it can cause pulmonary barotrauma, where expanding air damages your lung tissue, potentially leading to a collapsed lung or air embolism—a life-threatening condition where air enters the bloodstream and blocks blood flow to the brain or heart. These are not theoretical risks; they are immediate physiological dangers that arise from the loss of equipment function.
While the firm has reported only one incident involving a loose deflator button and no injuries have been recorded thus far, the absence of injury does not reduce the severity of the hazard. It simply means that, so far, luck has protected those affected. The potential for drowning remains acute because a vest that loses buoyancy can sink, pulling the diver down or making it impossible to surface safely if currents are strong or if the diver is exhausted. Continuing to use the recalled vest assumes that the button will hold every single time, but mechanical components under pressure and saltwater exposure degrade. By ignoring the recall, you are betting your safety on a component that has already been proven unreliable.
The real-world consequence of inaction is that you remain exposed to a known, unmitigated risk without any recourse if something goes wrong. The remedy offered—a free repair at a Mares scuba dealer—is designed specifically to eliminate this danger by securing the button properly. Choosing not to act leaves you vulnerable to an event that could result in serious injury, hospitalization, or worse, all because a simple safety step was delayed. In diving, equipment integrity is non-negotiable; treating a recall as optional undermines the very foundation of safe diving practices.
