Gpacers Diver Rescue System

One of the Worst Feelings a Diver Can Have...

Surfacing with land almost not in sight.
The boat is the size of a pinhead on the horizon.
The sun is going down behind you, and you know it’s shining straight into the captain’s eyes—so he can’t see your tiny SMB.

If that situation doesn’t resolve fairly quickly, none of the outcomes are good ones:

• A long swim to shore and a night in the dark under a coconut tree, swatting away mosquitoes
• Getting picked up by a passing superferry and taking an unwanted trip to wherever it’s headed, in a wetsuit with no money
• A third scenario… not even worth thinking about

Enter the Gpacers Diver Rescue System

All of this can be avoided by carrying a Gpacers Technology diver rescue system. It consists of:

• A radio transmitter carried by the diver
• A receiver and an iPad (or other device) with the Gpacer app installed, on the boat

This basic setup—used for self-contained, on-site monitoring—works best for us, especially since we operate in small wet boats.

For the initial setup, you’ll need an internet connection to download a map of the area you're diving in. Once saved, the app works completely offline, so you’re covered even in the most remote locations.

The receiver is placed on the highest point of the boat—in our case, roughly 2.5 meters above the water—giving us about a 6 km range. Once turned on, the receiver appears in the center of the map, knowing its location via GPS.

Now, if a diver surfaces and can’t see the boat for any reason, they just turn on their transmitter, and their location pops up on the map. The boat can go straight to them. We can also trigger an audible alarm to get the crew’s attention if they're focused on something else.

It’s that simple, and that easy to understand.

Why This Matters

Diver searches are stressful, expensive, and often depend too much on luck—especially since it’s usually hours after a diver goes missing that the boat reports it and support is dispatched.

This system changes everything.
It becomes almost impossible to lose a diver in the first place.
We can “see” where they are as soon as they surface.

The level of comfort this gives both divers and operators can’t be overstated.

Even if the boat breaks down and can’t reach the diver, the app records a visible drift history. That means rescuers know exactly which way the diver is drifting—no need to guess where to begin the search.

Gpacer makes everything as secure as it can reasonably be.

Flexible and Scalable

The system can be tailored to your needs:

• Simple on-site monitoring, like we use
• A base station setup on a liveaboard or large resort
• Monitoring multiple boats and dive teams over wide areas

Next time you're diving at Tech Asia, you'll see this in action.
