*Converted from £395 GBP sale price
Each option offers unique features tailored to different rowing scenarios. For example, the SpeedCoach GPS 2 is a standout choice for its rowing-specific design, offering precise real-time data and compatibility with the NK LiNK Logbook app for both iOS and Android. This makes it especially appealing for coaches managing multiple athletes. As Jim L. noted:
"Great piece of equipment for data-driven coaches!"
Waterproofing is another critical factor. The SpeedCoach GPS 2 boasts IP67 and NEMA-6 ratings, making it ideal for wet, marine environments. In contrast, fitness watches like the Garmin Fenix 7 Series are rated at 5ATM, suitable for submersion up to 164 feet. Apps like CrewNerd and RowHero, however, depend on your smartphone’s water resistance, which could be a limitation on the water.
Cost is another consideration. The SpeedCoach GPS 2 is a one-time $469 investment, while apps like RowHero require ongoing subscription fees. Dedicated devices like the SpeedCoach also provide better durability, longer battery life, and impeller compatibility, ensuring more accurate current measurements compared to smartphone apps.
Ultimately, the best device depends on your training goals and how much you value features like durability, battery life, and data integration. Whether you’re a competitive rower, a coach, or someone just starting out, there’s an option to fit your needs.
Final Thoughts
Choosing the right GPS device depends on your rowing preferences and goals. The options in our top five cater to different priorities, so there’s something for everyone.
If you’re a competitive rower or a serious athlete, the SpeedCoach GPS 2 is hard to beat. Designed specifically for rowing, it provides real-time performance data with impressive accuracy – essential for competitive racing. Coaches will also appreciate its wireless data transfer to various devices, making the $469 price tag worthwhile thanks to its reliability and specialized features.
For those who enjoy rowing as part of a broader fitness routine, the Garmin Fenix 7 Series is a strong contender. Although it lacks rowing-specific features, its versatility across multiple sports and durable waterproof design make it a great choice for cross-training.
Budget-conscious rowers might lean toward CrewNerd, which delivers basic metrics without breaking the bank. Meanwhile, indoor rowers may find RowHero appealing, though its subscription model is worth considering.
It’s worth noting that smartphone-based solutions, while convenient, come with limitations. Their accuracy depends on your phone’s GPS capabilities, water resistance, and battery life, which could fall short during extended sessions. On the other hand, standalone GPS devices offer more reliable satellite connections and better precision. For serious training, where accurate metrics make a difference, this reliability is a game-changer.
That said, no technology can replace the essentials. Mastering rowing fundamentals and staying attuned to the water remain the foundation of effective training.
FAQs
What should I consider when choosing a GPS device for rowing that fits my needs and budget?
When picking a GPS device for rowing, it’s important to think about your goals and budget. If you’re after a cost-effective option, the Garmin eTrex 32x delivers dependable tracking for distance and time without stretching your wallet. On the other hand, if you’re interested in advanced features like heart rate monitoring and activity tracking, the Garmin Vivoactive HR is an excellent choice for rowing enthusiasts.
Key factors to keep in mind include ease of use, battery life, water resistance, and how well the device fits into your rowing routine. Whether you’re hitting the water or training indoors, selecting a GPS device that matches your needs can make a big difference in enhancing your rowing sessions.
What are the main differences between a GPS device and a smartphone app for rowing?
Dedicated GPS devices are designed to be tough and dependable, featuring waterproof construction, extended battery life, and the ability to function without relying on cellular networks – making them perfect for rowing in remote areas. On the other hand, smartphone apps are cheaper and more flexible, offering regular updates and advanced mapping tools. However, they depend on cell service and aren’t as durable for outdoor adventures.
Why is the waterproof rating of a GPS device important for rowing?
When you’re rowing in wet conditions, the waterproof rating of your GPS device becomes a key factor in its durability and reliability. A rating of IP67 or higher means the device can withstand splashes, rain, and even being briefly submerged – up to 3.3 feet for 30 minutes. This level of protection ensures your device stays functional, letting you track your distance and time without worrying about water damage, even in tough on-water scenarios.
