Frequently Asked Questions
Can I wear these trackers in saltwater or at the beach?
Yes—devices with a 5 ATM or water-resistant rating are designed for swimming and beach use. After exposure to saltwater, rinse the device and strap with fresh water and dry thoroughly to prevent corrosion or lingering odors.
Do these devices track swim stroke type and lap counts accurately?
The ULTRAK 495 stopwatches include dedicated stroke and frequency modes and reliable lap recall for coached sessions. Wrist trackers like the Amazfit Band 7 offer swim modes and automated lap counting, but wrist-based stroke classification can vary with stroke style and fit—expect good general metrics but not professional-level stroke analysis.
Will these trackers give me GPS routes for open-water swims?
The reviewed ULTRAK stopwatches focus on timing and stroke data rather than GPS route mapping. The Amazfit Band 7 emphasizes battery life and swim modes; it does not advertise built-in GPS in the product features shown here. If detailed route tracking is crucial, look for a device that explicitly lists built-in GPS in its specifications.
