Some fancy cars have HUD displays. MPH, speed limit, map directions, and other information can be projected on the windshield. Now similar functions can be found in swimming goggles! Here’s more from Wareable!
The built-in heart rate monitoring negates the need for additional wearables (though integration with the Apple Watch and Garmin watches remains), and Form’s internal tests suggest the accuracy can match up pretty closely to a chest strap.
We’ll be showing our own findings in our full Smart Swim 2 review (coming soon), but the company indicates that these latest goggles exhibit an average deviation of +/- 4 BPM compared to the chest strap, whereas a typical wrist-based optical heart rate monitor showed a variance of +/- 10 BPM.
