Being careful is not a system

Supervision matters. Fences matter. Swim lessons matter. But real life is full of distracted moments, wrong assumptions, and quiet lapses that feel small until they are not.

BCone adds one more layer of protection for the moments you cannot fully control. It's the silent guardian that never blinks.

How BCone Works →

For the moments you worry about most

After bedtime when everyone is asleep.

When guests are over and distractions are high.

When one adult thinks the other is watching.

When your toddler is faster than expected.

"BCone is there for the moments when the pool should not be part of the story."

Ready when it matters

Precision engineering that's incredibly easy to use. No complex wiring or professional installation required.

1

Place & Activate

Place BCone in the pool and set it to On Mode when no one should be in the water.

2

Detect & Alert

If pool entry is detected, the system sounds an alarm at the pool and inside the home, and alerts your phone.

3

Swim Mode

Switch to Swim Mode when in use. It automatically reactivates after the water settles — so you never forget to turn it back on.

BCone system — pool unit, home unit, and app

Built for real peace of mind

Dual-Siren System

Loud alarm sounds simultaneously at the pool unit and the indoor home unit, ensuring you hear it wherever you are.

Instant App Alerts

Get critical notifications sent directly to your phone the moment water entry is detected.

5 Sensitivity Levels

SMART TECH

Automatic Re-arming

After Swim Mode, BCone automatically reactivates itself once the water has been still for several minutes — no forgetting to turn it back on.

What parents want to know

No. After Swim Mode, BCone automatically re-arms itself once the water has been calm for several minutes. You never need to worry about forgetting to turn it back on.
Not at all. BCone requires no wiring or professional installation. Place it in your pool, pair the home unit via the app, and you're protected within minutes. The pool unit runs on 2 standard AA batteries lasting up to 18 months. The home unit charges via USB-C.
BCone works with in-ground and above-ground pools, spas, hot tubs, and garden ponds. One unit covers up to 20' × 40'. For larger pools, connect up to 4 pool units to a single home unit. It's also IP68 waterproof certified and works with saltwater and chlorine pools.
No. BCone is designed to be one additional layer of protection, not a replacement for adult supervision, fences, or swim lessons. It's the backup for the moments that slip through.

Put it in place before you need it

The best time to add another safety layer is before the moment that makes it obvious. Protect your pool, protect your peace of mind.
