Does the HandPlus B2 work in open water?
Yes. It is designed for heart rate monitoring in both pools and open water.
Can I see my heart rate inside my goggles?
Yes, when HandPlus B2 is paired with compatible HoloSwim goggles, it displays real-time heart rate data directly in your field of view.
Which HoloSwim goggles are compatible?
HandPlus B2 can be paired with HoloSwim 2 Pro or HoloSwim 2S for real-time heart rate display in the goggles.
Does it support HoloSwim 3 Pro?
Support for HoloSwim 3 Pro is expected in September 2026, so it is not the right choice if you need that compatibility immediately.
Who is this best for?
It is best for swimmers who want stable, high-precision heart rate monitoring during swim sessions, especially those training with compatible HoloSwim goggles.
