7 Best Tracking Devices For Open Water Swimming Rated

Watching your child transition from splashing in the shallow end to confidently tackling open water is a major milestone in their athletic development. Finding the right tracking device can turn a simple swim into an empowering data-driven journey that builds their self-discipline and focus. This guide helps you navigate the technology landscape to find the perfect fit for your young swimmer’s current stage and long-term goals.

Garmin Swim 2: Best for Open Water Metrics

When your 11-to-14-year-old starts expressing a serious interest in competitive open water swimming, you want a device that speaks their language. The Garmin Swim 2 is purpose-built for the pool and the lake, offering dedicated modes that track distance, pace, and stroke count with impressive precision.

It’s a fantastic "bridge" device. It offers the professional-grade metrics a developing athlete craves without the overwhelming complexity of a high-end multisport watch. If your child is moving from casual summer camps to structured club training, this is a solid, durable investment that won’t feel like "kiddie gear."

• Best for: Competitive youth swimmers (ages 12+).
• Bottom line: A reliable, focused tool that rewards technical improvement.

Apple Watch Ultra 2: Top Multisport Tracker

If you have a teen who is involved in everything from cross-country running to ocean swims, the Apple Watch Ultra 2 is the ultimate "all-in-one" solution. It is rugged enough to handle the salt and sand of the beach while providing a familiar interface for kids who are already tech-savvy.

While it is a significant financial commitment, its longevity is its secret weapon. Because it functions as a lifestyle watch, it stays useful long after the swim season ends. For the multi-sport athlete, this device eliminates the need to buy three separate trackers, making it a surprisingly practical choice for the busy family.

• Best for: The active teen involved in multiple sports.
• Bottom line: A premium, versatile investment that grows with a teenager’s diverse interests.

Coros Pace 3: Reliable GPS for Open Water

Many parents worry about buying expensive gear that might end up in a drawer if a child changes their mind about a sport. The Coros Pace 3 strikes a rare balance: it is incredibly affordable compared to its competitors, yet it offers the high-end GPS accuracy needed for open water navigation.

It’s lightweight and low-profile, which is a major plus for younger swimmers who might find bulky watches distracting or uncomfortable during long strokes. For a 10-to-13-year-old just starting to explore lake swimming, this provides professional-level data without the "pro-athlete" price tag.

• Best for: The budget-conscious parent supporting a budding swimmer.
• Bottom line: High performance at a sensible price point that minimizes financial risk.

Suunto Race: Best Battery for Long Swims

Is your child training for longer distance events or open water clinics that last several hours? The Suunto Race is the endurance king, boasting a battery life that outlasts almost anything else on the market, ensuring the data never cuts out halfway through a long session.

This watch is best suited for older, highly committed teens who are tracking their progress over long distances. It’s a specialized tool for the athlete who has already moved past the "beginner" phase and is now focused on stamina and endurance benchmarks.

• Best for: Long-distance endurance training and advanced youth athletes.
• Bottom line: Unmatched battery reliability for the dedicated distance swimmer.

Polar Vantage V3: Advanced Heart Rate Data

Understanding how hard the heart is working is a key lesson in physiological self-awareness for young athletes. The Polar Vantage V3 is renowned for its heart rate monitoring accuracy, helping older students learn to pace themselves and avoid burnout during intense training.

This device is ideal for the 14+ age group, where understanding recovery and exertion becomes as important as speed. It provides the kind of analytical depth that can help an athlete work smarter, not just harder, as they prepare for high school or collegiate-level competition.

• Best for: Older teens focused on physiological metrics and recovery.
• Bottom line: A data-rich tool that teaches the science behind athletic performance.

Form Smart Swim Goggles: Heads-Up Display

Sometimes, the best way to help a child improve is to give them immediate, real-time feedback. Form goggles project your child’s pace and distance directly onto the lens, removing the need to stop and look at a watch—which is a game-changer for maintaining a smooth, efficient stroke.

This is particularly helpful for visual learners who struggle to "feel" their pace. While it’s a unique piece of equipment, it can be a massive confidence booster for a child who needs to see their progress to stay motivated.

• Best for: Visual learners and swimmers working on stroke rhythm.
• Bottom line: Revolutionary feedback that makes training feel like a video game.

Finis Smart Goggle: Real-Time Pace Tracking

If your child is a data-driven learner who loves seeing numbers tick up, the Finis Smart Goggle is a fantastic entry point into wearable tech. It is less intrusive than a watch and focuses purely on what matters in the water: keeping a consistent pace.

These are excellent for younger swimmers (ages 9-12) who might find a watch on their wrist distracting during their stroke. By keeping the display in their line of sight, they learn to self-correct their speed naturally, fostering independence in their training sessions.

• Best for: Younger swimmers who find wrist-worn tech distracting.
• Bottom line: A clever, unintrusive way to build pace awareness.

Essential Safety Gear for Open Water Swimmers

No matter which tracker you choose, safety must always be the priority in open water. A bright, high-visibility swim buoy is non-negotiable; it makes your child easily visible to boaters and provides a place to rest if they become fatigued.

Additionally, always consider a brightly colored silicone swim cap for visibility. For younger children, ensure they are swimming in areas with lifeguards or within a clear, supervised boundary, regardless of how "smart" their tracking device is.

• Safety Tip: Always pair tech with a high-visibility buoy.
• Bottom line: Technology is for tracking, but safety gear is for surviving.

Understanding GPS Accuracy in Open Water

It’s important to manage expectations: GPS signals struggle in water. When your child’s hand enters the water during a stroke, the GPS signal is momentarily blocked, which can lead to slight variations in distance tracking compared to a run.

Explain this to your child so they don’t get frustrated by minor discrepancies. Teaching them that these devices are tools for trends—rather than laser-perfect measurements—is a great lesson in managing data and focusing on personal improvement over perfection.

• Developmental Lesson: Teach kids to focus on their own progress, not just the device’s numbers.
• Bottom line: GPS in water is an estimate; use it as a guide, not an absolute truth.

How to Choose the Right Swim Tracking Device

When deciding, look at your child’s commitment level rather than their age alone. A 10-year-old who swims competitively year-round may need a different tool than a 14-year-old who swims for cross-training.

Consider the resale value and sibling hand-me-down potential. Brands like Garmin and Coros often hold their value well, making them easier to pass on or sell if your child’s interests shift. Ultimately, the best device is the one that makes your child excited to get in the water.

• Decision Matrix:
  • Casual/Beginner: Affordable, simple interface (e.g., Coros).
  • Competitive/Serious: Durable, advanced metrics (e.g., Garmin, Polar).
  • Multisport/Teen: Versatile, high-tech (e.g., Apple Watch).
• Bottom line: Match the device to their current passion, not their future potential.

Investing in a swim tracker is about more than just logging laps; it’s about giving your child a sense of ownership over their own athletic journey. By choosing a device that aligns with their current developmental stage, you are providing them with the tools to build discipline and self-awareness. Trust your instincts as a parent, and remember that the best results come from the joy of the swim itself, not just the data on the screen.
