You’ll need a swim tracker with at least 5 ATM water resistance for safe pool swimming, which handles water pressure up to 50 meters deep. Look for IPX7 or IPX8 ratings too—IPX7 protects during 30-minute immersion up to 1 meter, while IPX8 offers superior protection for deeper, longer sessions. Popular models like Garmin Fenix 8, Apple Watch Ultra 2, and Fitbit devices typically meet these standards. However, real-world conditions differ from lab testing, and you’ll discover why proper maintenance becomes essential for long-term performance.
Understanding ISO 22810:2010 Standards for Swimming Devices
When you’re shopping for a swim tracking device, you’ll encounter the ISO 22810:2010 standard—a thorough testing protocol that determines whether your device can actually handle water exposure.
This International Organization for Standardization framework puts devices through rigorous pressure testing, immersion trials, and condensation checks to simulate real-world swimming conditions. The comprehensive testing includes evaluations for overpressure resistance, shallow depth performance, strain tolerance, and thermal shock resilience to ensure devices meet strict aquatic safety requirements.
You’ll see devices classified by water resistance ratings measured in meters or atmospheres. A 100-meter rating means your device supports recreational swimming and water sports, while higher ratings accommodate professional marine activities.
The standard guarantees manufacturers use specific symbols and terminology when marking their products, so you’ll know exactly what activities your device can handle.
ISO 22810:2010 ensures clear product labeling so consumers understand their device’s true water resistance capabilities before purchase.
Proper compliance means you can trust your swim tracker won’t fail during aquatic workouts.
ATM Vs IP Rating Systems Explained
You’ll encounter two main rating systems when shopping for swim tracking devices: ATM ratings that measure pressure tolerance underwater, and IP ratings that focus on preventing water and dust from entering your device.
While ATM ratings tell you how deep your device can theoretically go, IP ratings show how well it blocks water intrusion from splashes, sprays, and immersion. Keep in mind that water resistance isn’t permanent since seals can degrade over time and with exposure to heat and temperature fluctuations.
Understanding both systems helps you choose devices that offer dual protection—pressure resistance for swimming depth and ingress protection for everyday water exposure.
Pressure Vs Ingress Protection
Understanding water resistance ratings requires distinguishing between two fundamentally different measurement systems that serve distinct purposes. ATM ratings measure your device’s ability to withstand static water pressure at specific depths, while IP ratings evaluate protection against both water ingress and solid particles under various exposure conditions.
| ATM Rating | IP Rating |
|---|---|
| Measures static pressure resistance | Measures ingress protection from water and dust |
| Depth-based (10m per ATM) | Exposure-type based (jets, immersion, splashes) |
| Ideal for swimming at constant depths | Better for dynamic water conditions |
| Doesn’t account for moving parts | Covers extensive environmental protection |
You’ll find ATM ratings focus solely on pressure tolerance, making them suitable for swimming activities. IP ratings offer broader protection, covering water jets, dust, and varied exposure scenarios that modern swim trackers often encounter. The ATM system originated from traditional watch manufacturing, where 1 ATM equals 10 meters of water pressure, establishing the foundation for modern waterproof standards.
Dual Rating Benefits
Since many swim tracking devices now feature both ATM and IP ratings, you’ll benefit from understanding how these dual systems work together to provide ample water protection.
When you see both ratings on a device, you’re getting thorough information about static pressure resistance and ingress protection against particles and water.
The dual rating approach gives you complete transparency about your device’s capabilities. ATM ratings tell you the exact water depth your tracker can handle, while IP ratings specify protection against dust, debris, and different water exposure types.
This combination helps you make informed decisions based on your swimming activities. Regular inspection of your device’s water resistance features ensures continued performance and helps maintain the integrity of both rating systems over time.
You’ll find dual ratings particularly valuable when comparing devices, as they eliminate guesswork about water resistance limitations and environmental protection levels.
5 ATM and IPX7/IPX8 Requirements for Pool Swimming
When you’re choosing a swim tracker for pool use, you’ll need at least a 5 ATM rating to handle the water pressure and submersion safely.
IPX7 provides basic protection for brief swimming sessions, but IPX8 offers the continuous immersion protection that’s better suited for longer pool workouts.
However, these lab-tested ratings don’t account for the dynamic forces you create while swimming, which can stress seals and components beyond their static test conditions. Most quality swim trackers are water-resistant up to 50m, providing adequate protection for recreational and competitive pool swimming.
5 ATM Pool Standards
While many swimmers focus solely on whether their device can handle water, the specific water resistance standards matter considerably more than a simple “waterproof” claim.
You’ll need to understand ATM ratings, which measure static pressure equivalent to water depth—1 ATM equals 10 meters of water pressure.
For pool swimming, you should look for devices rated at least 5 ATM (50 meters depth). This rating guarantees your device can handle surface swimming and shallow dives without water ingress.
However, remember that ATM ratings measure static pressure, not dynamic pressure from your swimming movements, which can increase effective pressure on your device.
Devices below 5 ATM might resist splashes but won’t survive sustained pool sessions. After each swimming session, you should rinse your device with fresh water to remove chlorine and other chemicals that could potentially damage the seals over time.
IPX7 Vs IPX8 Differences
ATM ratings tell only part of the water resistance story for swim tracking devices.
You’ll find that IPX7 and IPX8 ratings provide more relevant protection standards for modern swim trackers with integrated electronics.
IPX7 protects your device during immersion up to 1 meter deep for 30 minutes. It’s adequate for short swimming sessions and accidental water exposure, but you’re limited to shallow pool areas.
IPX8 offers superior protection for continuous immersion beyond 1 meter, with manufacturer-specified depth and duration limits.
You can swim longer sessions and use deeper pool areas without worry.
Since most pools have deep ends reaching 3 meters, IPX8-rated devices provide better versatility.
You’ll get reliable sensor functionality during backstroke, diving, and extended swim tracking sessions that IPX7 devices can’t handle. These ratings follow the IEC 60529 standard which establishes the testing protocols for water ingress protection.
Dynamic Swimming Force Limitations
Beyond static water pressure ratings, dynamic forces from your swimming movements create additional pressure that affects device performance.
When you swim, the water resistance against your moving arms creates dynamic pressure equivalent to approximately 5 meters of additional water depth beyond the device’s static rating.
However, competitive swimmers typically don’t generate more than 50 kPa of dynamic pressure, which equals just 5 meters of extra depth pressure.
Manufacturers already account for these forces by applying 125% safety margins to their test pressures.
This means you don’t need extremely high ATM ratings for pool swimming—contrary to common misconceptions. Professional maintenance checks every 12 to 18 months help ensure your device continues to perform reliably under these dynamic conditions.
- Dynamic pressure adds roughly 5 meters to effective depth exposure
- Competitive swimming rarely exceeds 50 kPa additional pressure
- Safety margins of 125% already account for movement fluctuations
- Overestimating dynamic effects leads to unnecessary high-rating purchases
Popular Swim Tracker Models and Their Water Resistance Ratings
When choosing a swim tracker, you’ll find that different brands offer varying levels of water resistance alongside distinct tracking capabilities. Most swim-focused devices feature 5 ATM or 50-meter water resistance ratings, ensuring they’ll handle pool sessions and open-water activities without damage.
| Brand | Model | Water Resistance | Key Features |
|---|---|---|---|
| Garmin | Fenix 8 | 5 ATM | Extensive swim tracking, deep-sea activities |
| Coros | Pace 3 | 5 ATM | Four stroke detection, 30g weight |
| Apple | Watch Ultra 2 | 50 meters | Underwater heart rate, advanced metrics |
| Fitbit | Various Models | 50 meters | Continuous HR monitoring, triathlon support |
You’ll notice that while water resistance ratings remain consistent across brands, each manufacturer focuses on different tracking strengths to meet swimmers’ specific needs. Top-tier models like the Garmin Fenix 8 offer SWOLF measurements that help swimmers analyze their efficiency by combining stroke count and time data.
Real-World Swimming Performance Vs Laboratory Testing
While manufacturers test water resistance under controlled laboratory conditions, your swim tracker’s real-world performance will likely differ greatly from these ratings.
Lab tests use static fresh water without movement, temperature fluctuations, or physical stress. However, when you’re swimming, dynamic water pressure from arm movements, temperature changes, and chemical exposure from chlorine or saltwater can compromise your device’s waterproofing over time.
Your tracker’s accuracy will also decrease considerably during actual swimming. Water turbulence and rapid arm movements introduce measurement noise, causing heart rate readings to deviate by 13-56 bpm from accurate measurements. The faster and more intensely you swim, the worse these deviations become. Additionally, sweat exposure can be more damaging to your device than water immersion, as sweat contains corrosive salts that can degrade seals and internal components.
- Dynamic water pressure from swimming creates stress not present in static lab tests
- Temperature fluctuations cause seals to expand and contract, potentially compromising water resistance
- Pool chemicals and saltwater can corrode gaskets and degrade waterproofing capabilities
- Measurement accuracy drops considerably, with heart rate deviations increasing by 49-52 bpm during active swimming
Maintaining Water Resistance Over Time and Usage
Even though your swim tracker passes initial water resistance tests, its protective barriers will deteriorate with regular use and environmental exposure. Salt water, chlorinated pools, and temperature changes weaken seals and adhesives over time. You’ll notice degradation after 1-2 years of frequent swimming through fogging screens, charging issues, or corroded ports.
| Environmental Factor | Impact on Device | Prevention Method |
|---|---|---|
| Salt water exposure | Accelerates corrosion around buttons | Rinse immediately with fresh water |
| Pool chemicals | Degrades seals and coatings | Activate water lock before swimming |
| Temperature fluctuations | Weakens adhesives | Avoid hot showers and saunas |
You can extend your device’s water resistance by following manufacturer guidelines, cleaning charging contacts with a soft brush, and seeking professional maintenance when you notice deterioration signs. After each water activity, immediate cleaning is essential to prevent residue from drying on your device and compromising its sensitive components.
