Smart Marine Bilge Alarm

Detect rising bilge water levels—even slow buildup—before it turns into mold, foul odors, or a sinking risk.

Boxed bilge alarm sensor.

Never Worry About Rising Water

The Smart Bilge Sensor uses a marine-grade float switch and temperature sensor to notify you the moment trouble starts. Alerts go out via voice call, SMS, email, and app push notifications—repeating every 3 hours until resolved—and can also notify your marina or service provider instantly.

Why It's A "Must Have" Sensor

Prevent Sinking & Water Damage: Monitors water presence continuously to spot early accumulation or sudden leaks.

Avoid Mold & Odor: Prevents long-term dampness caused by stale rainwater in the bilge.

Freezing Alerts: Notifies you if temperatures drop below 2 °C—protecting against freeze damage.

Multi-Channel, Persistent Alerts: Alerts repeat every 3 hours until addressed, ensuring you, your emergency contacts, and your marina stay in the loop.

How It Works

1. Mount & Activate: Position the float switch in the bilge; hold it in the raised position for 30 seconds to avoid false alarms.

2. 24-Hour Self-Checks: Daily health checks ensure the sensor is operating correctly.

3. Float Switch Detection: Rising water lifts the float; once triggered, alerts are sent via voice, SMS, email, and push notifications.

4. Marina & Providers Alerted: If configured, your marina or proactive care provider receives the same alerts for a coordinated response.

Boaters’ Insights on Lokket’s Smart Marine Sensors

We've been with Lokket for a couple of years now, and their customer service is great, the equipment keeps getting better and the price has gotten lower! Who does that? Very responsive when there were issues, even on weekends and holidays. The equipment now is very stable and the Internet is super-fast, and the price is extremely reasonable.

Have had Lokket on my boat in San Diego for years now and it works amazingly well. My boat has been moored in 2 different marinas and the signal has been strong and consistent at both. Technical service, while rarely needed, has always been provided quickly and efficiently... usually the same day.

I have been living on my 45-foot sailboat in America's Cup Harbor on Point Loma since November 2018. I joined Lokket WiFi in January 2019 and have been totally satisfied with their internet service. My internet connection has been extremely reliable and, on those infrequent occasions when there has been an issue, Eric and his team have been promptly responsive. They have been proactive in offering me of equipment upgrades. Lokket's billing system has dependably serviced my account without fail or complication. In reviewing my account, I found that my e-mails are answered within a day, and my few issues were resolved quickly - often on the same workday. As a retired Navy destroyer captain, I value Lokket's WiFi service reliability and dependable customer service to this afloat account. Well Done!

For the last two years my WIFI service from Lokket has been excellent. Upload and download speeds far better than my Cox service at home, and at a much lower cost. Having the right equipment is important, and your location in the Marina is much less of an issue than years ago.

Dockmaster - Fifth Ave Landing
We hired Lokket to upgrade our WiFi and security cameras at Fifth Avenue Landing Marina 2 years ago. Making the switch from Cox to Lokket was the best decision we could have made and we are immensely happy with their service. Our superyacht Captains, crew and guests have been 100% satisfied with the internet speeds (no small feat when you have 100+ users). The security cameras are high quality, reliable and able to store recordings which has been an added value to our security protocol at the Marina. Lokket's offerings are fantastic and they continue to provide excellent support and service.

We use Lokket wifi and security cameras on the entirety of our property at Kona Kai Marina. Since we switched from Cox, we have had excellent wifi in our office and for the boats in our marina. Our 540 tenants rave about how good the service is on their boats. Security cameras are high quality and easy to use. Their service is fast and effective. They really have changed the game for marina wifi and we couldn't be happier.
