What was recalled
In July of 2022, the U.S. Consumer Product Safety Commission announced a significant safety recall involving specific SCUBA diving computers manufactured by Aqualung. This is not a vague or broad warning; it targets precise models that were designed to help divers monitor their depth and time underwater. The affected product is the i330R SCUBA Diving Computer, a wrist-worn device intended for use during recreational diving. If you are a diver who owns this piece of equipment, it is crucial to understand exactly which units are part of this recall so you can take immediate action.
The devices in question are characterized by their distinct physical appearance. They feature a black wristband and case, paired with a bright color display that makes readings easy to see underwater. The interface includes two buttons for navigation and control. For identification purposes, the brand name "AQUA LUNG" is clearly printed on both the front and back of each device. To determine if your computer is affected, you must look at the back of the unit where the model number and serial number are located. These numbers are also accessible by scrolling through the menus on the diving computer itself.
The recall covers three specific configurations of the i330R, differentiated by the type of gauges they display and their internal sensor types. The first affected model is the Black/NS159000 (GD-001004 to GD-015302), which features a 2-GAUGE, PSI console. This variant was manufactured in February 2021 and February 2022, with approximately 14,000 units affected. The second model is the Black/NS159001 (GM-001000 to GM-003305), which displays a 2-GAUGE, BAR console. This version was produced in December 2021 and February 2022, affecting about 2,200 units. The third affected model is the Black/NS159002 (GM-001011 to GM-001269), also a 2-GAUGE, BAR console, manufactured during the same period in late 2021 and early 2022, with 129 units impacted.
While the recall notice does not specify every retailer or website where these items were originally sold, it confirms that these specific serial number ranges were distributed to consumers between December 2021 and February 2022. If your dive computer falls within any of the model and serial number ranges listed above, it is part of this recall. The scope of this issue is substantial, touching tens of thousands of devices worldwide. Because these computers are critical safety tools, identifying the exact hardware you own is the first step in ensuring your safety.
The hazard, explained
At the heart of this recall is a critical software error within the Aqualung i330R SCUBA Diving Computers that fundamentally compromises the device’s ability to keep you safe underwater. To understand why this matters, it helps to look at how these computers work in the first place. Modern dive computers are sophisticated calculators that monitor your depth and time to ensure you ascend slowly enough to avoid decompression sickness (the bends). They do this by calculating "no-stop limits" based on the pressure of the water around you. However, air pressure changes with altitude. At sea level, the atmospheric pressure is standard. But as you travel higher up in elevation, the air becomes thinner, and the ambient pressure drops.
The specific flaw identified in this recall affects how the i330R handles these altitude adjustments. When a diver takes their computer to a location that is more than 3,000 feet above sea level—such as high-altitude lakes in Colorado, mountain streams in Montana, or diving sites in the Andes—the device fails to properly adjust its baseline calculations. Instead of recognizing that the lower atmospheric pressure requires different safety margins, the computer continues to use sea-level data. This creates a dangerous illusion of safety.
Here is how that technical failure translates into physical risk. Because the computer does not account for the reduced pressure at altitude, it may calculate dive times and ascent rates incorrectly. It might tell you that you are safe to stay down longer than you actually are, or that your ascent rate is acceptable when it is actually too fast. In practical terms, this means your body could be absorbing more nitrogen than the computer thinks it should. If you follow the computer’s incorrect guidance and ascend normally, the nitrogen trapped in your tissues can form bubbles, leading to decompression sickness. This is a serious medical condition that can cause joint pain, paralysis, organ damage, or even death.
Beyond decompression sickness, there is an immediate risk of drowning. If the computer provides incorrect data regarding gas consumption or depth limits, a diver might run out of air unexpectedly or fail to surface in time. In open water, especially at altitude where currents can be unpredictable and help is far away, these miscalculations are not just inconveniences; they are life-threatening errors. While the Consumer Product Safety Commission (CPSC) notes that only one incident has been reported so far involving an incorrect calculation display, the potential for severe injury or drowning remains a significant concern because the error is hidden from the user until it is too late. The device looks and acts like a normal computer, giving you false confidence while silently miscalculating your safety parameters.
Who is most at risk
The primary group at risk in this recall consists of recreational and technical divers who operate their Aqualung i330R SCUBA Diving Computers at altitudes exceeding 3,000 feet. While the device is designed to handle various diving conditions, its specific failure mode—displaying incorrect calculations for sea level dive times when used above this elevation threshold—creates a silent but dangerous trap. This hazard does not discriminate by age or experience level in terms of who physically possesses the device, but it disproportionately endangers divers who travel to high-elevation dive sites. These individuals might include those visiting mountain lakes, diving at resorts located in the Rockies or Andes, or participating in technical dives that require decompression stops at significant depths and altitudes.
The vulnerability here is compounded by the nature of scuba diving itself. Divers relying on these units are often in an environment where margin for error is virtually nonexistent. When a dive computer fails to adjust to altitude, it may calculate ascent rates and no-decompression limits as if the diver were at sea level. For a novice diver who is still building their situational awareness, this incorrect data can lead to catastrophic decisions, such as ascending too quickly or staying underwater longer than is safe. The risk of decompression sickness (the bends) increases significantly because the body absorbs nitrogen differently under pressure and altitude changes; if the computer does not account for the reduced atmospheric pressure at high altitudes, it cannot provide accurate safety windows.
Elderly divers or those with underlying health conditions may be at greater risk of severe consequences from decompression sickness. While the device itself poses a mechanical failure risk to all users, the physiological impact of an error can be more devastating for older adults whose bodies may have reduced capacity to filter out nitrogen bubbles. Furthermore, because this is a wrist-worn device with a two-button interface, divers wearing thick gloves in cold water or those with limited dexterity might struggle to notice the discrepancy between their expected dive profile and what the screen displays until it is too late. The danger is particularly acute for solo divers or those who lack immediate access to emergency medical facilities, as decompression sickness requires hyperbaric treatment to resolve effectively.
It is also important to note that while no injuries have been reported in the incidents documented by the firm, the potential for drowning remains a serious concern. If a diver suffers from decompression symptoms due to incorrect computer guidance, their ability to swim safely to the surface or assist others can be severely compromised. Therefore, anyone who has taken their Aqualung i330R to high-altitude locations between February 2021 and February 2022 falls into this at-risk category, regardless of whether they noticed any anomalies during their dive.
How to tell if you have the recalled item
If you are a scuba diver or enjoy underwater exploration, taking a moment to verify your equipment is one of the most important things you can do for your safety. The recall specifically targets Aqualung i330R SCUBA Diving Computers, and because this is a piece of specialized gear that looks quite different from everyday electronics, it is essential to look at the device itself rather than just relying on memory. Start by examining the physical appearance of your dive computer. You are looking for a wrist-worn device that is primarily black in color. A key visual identifier is the bright color display screen, which stands out against the dark casing. Additionally, check the controls; this specific model features a two-button interface on the side or front panel.
Once you have confirmed the general look of the device, you need to verify the branding and model details. The name "AQUA LUNG" should be clearly printed on both the front and the back of the unit. However, brand names alone are not enough to confirm a recall, so you must locate the specific model number. This number is printed directly on the back of the device. For the i330R, the model number will begin with "NS15900" followed by a suffix that indicates the gauge type. Specifically, look for one of the following model numbers: NS159000 (for 2-Gauge PSI consoles), NS159001 (for 2-Gauge BAR consoles), or NS159002 (for another variant of the 2-Gauge BAR console). If your device has a different model number, it is not part of this specific recall.
The most critical step in identification is checking the serial number. This is where many people get confused, so please pay close attention. The serial number is printed on a label located on the back of the device. You need to compare this number against the affected ranges listed by the manufacturer. For model NS159000, the recalled units have serial numbers ranging from GD-001004 to GD-015302. If you have model NS159001, check if your serial number falls between GM-001000 and GM-003305. For model NS159002, the affected range is narrower, from GM-001011 to GM-001269.
If you cannot easily read the serial number on the back of the device, or if the label has worn off over time, there is an alternative way to find this information. You can power on your dive computer and scroll through the diving computer’s menu system. The model number and serial number will also be displayed digitally within the device’s software interface. This is particularly helpful if you have owned the device for a long time and the physical printing has faded. Finally, while the recall does not restrict where the item was sold, it is worth noting that these units were manufactured in February 2021 and February 2022. If your device falls outside these dates or does not match the serial ranges above, you likely own a safe, non-recalled version of the i330R. When in doubt, it is always safer to double-check the numbers against the official list provided by Aqua Lung.
What to do — step by step
If you own an Aqualung i330R SCUBA Diving Computer, your immediate priority is to ensure your safety and the safety of anyone else who might use the device. The recall notice is clear: you must stop using this specific piece of equipment right away. Do not take it on its next dive, and do not let a friend or family member borrow it for recreational use. The risk here is not theoretical; the computer may fail to adjust correctly to your altitude, potentially displaying dangerous errors regarding how long you can stay underwater at sea level when you are actually at higher elevations. These incorrect calculations can lead to decompression sickness or drowning. Therefore, the first and most critical step is to physically remove the device from your dive bag and keep it in a safe place where it cannot be accidentally grabbed for a trip until it has been properly addressed. Once you have secured the computer, you need to initiate the remedy process arranged by Aqua Lung. You have two distinct paths depending on your technical comfort level and access to resources.

What can happen if you ignore it
When a piece of safety-critical equipment like a scuba diving computer stops functioning correctly, the temptation to simply "keep going" or wait until next month for a repair can feel minor in the moment. However, continuing to use the recalled Aqualung i330R SCUBA Diving Computers without addressing the issue transforms a potential inconvenience into a life-threatening scenario. The core problem is not just that the device might be wrong; it is that it provides false confidence during one of the most technically demanding activities on earth.
The specific danger lies in how these computers manage decompression limits. When you dive at altitudes exceeding 3,000 feet, the atmospheric pressure changes significantly compared to sea level. The recalled units fail to adjust their internal calculations to account for this shift. Instead, they continue to display dive times and no-decompression limits as if you were at sea level. This is a silent, invisible error. You do not get an alarm, a flashing light, or a warning message. You simply see numbers that look correct but are fundamentally misleading.
If you rely on these incorrect calculations, you may stay underwater longer than your body can safely handle. As you ascend, the nitrogen dissolved in your bloodstream needs time to escape slowly through your lungs. If you ignore the computer’s faulty advice and exceed the safe limit for your actual altitude, that nitrogen forms bubbles in your blood and tissues. This condition is known as decompression sickness, often called "the bends." The consequences can range from painful joint pain and skin rashes to severe neurological damage, paralysis, or even death. In the context of being underwater, a sudden onset of symptoms can lead to loss of consciousness or motor control, directly increasing the risk of drowning before you can reach the surface or receive help.
While the manufacturer has reported one incident where the computer failed and displayed incorrect calculations, no injuries have been documented in their records so far. This lack of reported injuries is fortunate, but it does not mean the hazard is absent; it means that for some divers, luck intervened. Relying on luck is not a safety strategy. The device’s failure to adjust for altitude creates a gap between what you think is safe and what is actually safe. Ignoring this recall means stepping into that gap without any of the protective margins the computer was designed to provide.
Furthermore, trust in your gear is the foundation of dive planning. When your primary reference point for safety is compromised, every decision you make—how long to stay, how fast to ascend, and where to surface—becomes a gamble. By ignoring the recall, you are not just risking a technical error; you are compromising the entire safety architecture that keeps you alive underwater. The remedy is free and straightforward, but the cost of inaction is far too high to consider.
Staying safe: broader tips
While specific product recalls address immediate defects in particular batches, true safety in the world of scuba diving relies on a culture of continuous vigilance and proactive maintenance. Diving computers are sophisticated life-support devices that translate complex physiological data into actionable information for your brain under stress. Because no device is infallible, treating your gear with respect means understanding its limitations and verifying its integrity before every single dive. This section outlines general best practices that apply to all recreational divers, helping you build a safety net that extends beyond any single manufacturer’s warranty or recall notice.
First, never rely solely on the dive computer for critical decisions. Always carry a backup method of tracking your dive profile, such as a traditional analog depth gauge and a reliable timer or watch. This redundancy is crucial because electronic devices can suffer from battery failure, software glitches, or sensor errors—exactly the kinds of issues highlighted in recent industry recalls. If your primary computer fails to adjust for altitude or displays incorrect decompression data, having an independent reference point allows you to make conservative decisions, such as extending safety stops or aborting the dive early, rather than trusting faulty calculations.
Second, establish a rigorous pre-dive inspection routine that goes beyond just checking if the screen turns on. Before entering the water, physically inspect your dive computer’s seals and buttons for wear, corrosion, or damage. Ensure the display is legible in various lighting conditions, including low-light scenarios common at deeper depths. Furthermore, verify that your device has been properly calibrated according to the manufacturer’s guidelines. Many modern computers require altitude calibration before diving at elevation; failing to do so can lead to significant errors in no-decompression limits, just as seen in the Aqualung i330R issue. Regular servicing by authorized technicians is not optional—it is a fundamental requirement for maintaining the accuracy of your life-support equipment.
Third, stay informed about the broader health and safety landscape of your gear. Manufacturers occasionally update firmware to correct bugs or enhance features. Subscribe to newsletters from your dive equipment suppliers, join local dive shop loyalty programs, or follow official regulatory bodies like the U.S. Consumer Product Safety Commission (CPSC) on social media. These channels often provide early warnings about emerging hazards or voluntary recalls before they become widely publicized. Additionally, participate in regular safety briefings with your dive buddies. Discussing equipment quirks, battery status, and emergency procedures builds a shared awareness that can be life-saving if technology fails when you need it most.
Finally, remember that the best safety tool is a conservative mindset. Technology assists you, but it does not replace judgment. If your dive computer behaves unexpectedly—whether due to a known recall defect or an unknown glitch—trust your instincts and prioritize a safe ascent. Divers who combine updated knowledge, redundant equipment, and disciplined habits are far better equipped to handle the unpredictable nature of the underwater environment than those who rely on a single point of failure.
