A:Answer according to Google AI:
Correct, from a pure hardware and sensor performance standpoint, the Charge 6 offers no advantage over the Inspire 3 for tracking pool laps.Both devices use the exact same internal motion sensors to count your lengths, and both suffer from the same tracking limitations when submerged in water.
Where They Performed Identically
Lap Counting: Both use basic accelerometers to detect the change of direction when you turn at the pool wall.
Heart Rate Limits: Water interferes with the optical sensor on the back of both watches, making heart rate data equally unreliable on both during a swim.
Water Resistance: Both hold the exact same 5 ATM (50-meter) waterproof rating.
The Only Practical Differences in the Pool
While the data collected is identical, you may prefer one over the other based on these two purely physical design factors:
Screen Readability: The Charge 6 has a larger, brighter 1.04-inch screen, which makes it much easier to peek at your lap count through foggy swim goggles. The Inspire 3 screen is tiny (0.74-inch), making it difficult to read mid-workout.
Menu Navigation: The Charge 6 lets you adjust your pool length settings directly on your wrist right before your swim. On the Inspire 3, you generally have to rely on setting the pool length beforehand within the phone app.
If you already own the Inspire 3, upgrading to the Charge 6 will not give you better swimming data. If you are choosing between buying the two solely for pool workouts, the Inspire 3 gives you the exact same results for a lower price.
