ACR OLAS Exposure Series Tag Crew Overboard Tracker
ACR OLAS Exposure Series Tag Crew Overboard Tracker — Product description
The OLAS Exposure Series Tag is a wearable man overboard tracker that pairs to your phone over Bluetooth. If someone goes over the side, the app alarms within eight seconds and marks the GPS spot so you can turn around and get back to them fast. Small enough to clip to a life jacket, a kid, or the dog.
The OLAS Exposure Series Tag is a wearable crew tracker built around one job: knowing the instant someone leaves the boat. It talks to your phone or tablet over Bluetooth 4.1, and the free Exposure OLAS app keeps a virtual tether to every tag on board. Break that tether, and the alarm sounds within eight seconds.
Here's what that looks like in the real world. Someone goes over the side at night, or you're single-handing and lose your footing. The app catches the dropped connection, sounds off, and records the exact latitude and longitude where the tether broke using your phone's GPS. Then it points you back to that spot with clear visual bearing data so you're not guessing in the dark. Every incident is time-stamped and stored, which is exactly the information the rescue services ask for.
The tag itself is small, about 1.81 by 1.38 inches, and it weighs next to nothing. It ships with a universal silicone wrist strap and a stainless steel buckle, but you can clip it to a life jacket, a dog collar, a child, or a personal locator beacon. One phone tracks up to six tags at once, and any tag can be watched by an unlimited number of phones, so the whole crew can keep an eye on each other.
Boating alone? Turn on Solo mode and the app will text your emergency contact with GPS coordinates if you get separated from the boat. You do need a 2G phone signal for that one, so it's a coastal and inland feature, not a bluewater one.
Range covers vessels up to 40 feet, which suits most center consoles, sailboats, and cruisers. If you run something bigger or want a permanent setup that doesn't lean on a phone, the tag drops right into the larger OLAS ecosystem: the Guardian engine kill switch, the CORE base station, and the Extender that pushes coverage out to 80 feet. Start with one tag, scale when you need to.
The CR2477 lithium battery is user-replaceable and runs about 3,500 hours, roughly four months, in armed mode. Power it off between trips and it lasts a lot longer. It's waterproof to IP67, so spray and rain are no problem, but note that it does not float on its own.

Frequently asked questions
How fast does the alarm sound if someone goes overboard?
Within eight seconds. The app keeps a virtual tether to each tag over Bluetooth, and the moment that connection breaks it sounds the alarm and records the GPS position where it happened.
How many tags can one phone track at once?
One phone or tablet tracks up to six tags. And any single tag can be watched by an unlimited number of phones, so everyone aboard can monitor the whole crew.
Does the tag float if it lands in the water?
No, it doesn't float on its own. It's meant to be worn on a wrist strap or clipped to a life jacket, not tossed in the water as a marker.
What battery does it use and can I replace it myself?
It uses a CR2477 lithium coin cell that you can replace yourself. In armed mode it runs about 3,500 hours, roughly four months. Powering it off between trips stretches that a lot further.
How big a boat does it cover?
The tag covers vessels up to 40 feet. If you run something larger, adding the Extender pushes coverage out to 80 feet as part of the wider OLAS system.
Do I need cell signal to use it?
No. The tag pairs to your phone over Bluetooth, so man overboard alerts work with no cell coverage at all. The one exception is Solo mode, which sends an SMS to your emergency contact and needs a 2G signal to do it.
What comes in the box?
Each tag ships with a universal silicone wrist strap, a stainless steel buckle, and a pre-installed CR2477 battery, so it's ready to arm and wear out of the package.
