Smart GPS Locator for Real-Time Asset Tracking

 Track your boat, tender, outboard engine, or personal gear with precision.

Marine GPS Tracker for Boast and Yachts

Piece of Mind While Your Away

The Sense4boat Smart GPS Locator activates upon detecting motion and sends location updates—from every 10 minutes during movement to once per day when stationary. Its rugged, battery-powered (3×AA) design supports up to 5 years of power and uses the global Sigfox IoT network—no SIM card or boat wiring needed—for reliable, anti-jamming monitoring.

Why It's A "Must Have" Sensor

Effortless Theft Protection: Alerts triggered by movement notify you when your asset is used or moved.

Covert & Flexible Placement: Small, IP67-rated housing fits discreetly anywhere—under hatches, in engine compartments, or mounted on tenders.

Long-Lasting Battery: Powered by replaceable AA batteries with up to 5 years of life—depending on reporting frequency.

How It Works

1. Place & Activate: Mount the locator on your asset—no wiring required.

2. Motion Detection: The internal accelerometer wakes the device when movement is sensed.

3. Location Reporting: Sends updates every 10 minutes while in motion, then switches to daily check-ins when still.

4. Track via App: View live GPS/GLONASS positioning, set safe zones, and receive alerts through the Sense4Boat app if the asset moves unexpectedly.

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.

Fred came out and did a fantastic job of getting me up and running quickly and efficiently. I am extremely happy with the follow up on the service and the quality of both the installation and signal. Not to mention the incredible savings. Highly recommended. Thank you Eric and Fred and all support.

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.
