While the device delivers essential metrics for beginners, it lacks the advanced data some competitive swimmers might seek, such as stroke recognition or SWOLF (Swim Golf) scores.
Despite these limitations, the Inspire 3 stands out for its durability and ease of use, making it a practical option for those prioritizing basic swim metrics.
