Fabisense Mars

Invisible Gases. Real Dangers. One Compact Solution.

Every year, thousands of people are exposed to dangerous levels of carbon monoxide (CO) and carbon dioxide (CO₂) - often without ever realizing something is wrong. These gases are completely invisible, completely odourless, and completely capable of changing a normal, everyday moment into a life-threatening one.

You can’t see them.

You can’t smell them.

You can’t feel them until your body begins to fail.

That’s why we created the Fabisense Mars: 
a compact, elegant, intelligent device designed to detect danger before your body does.

Engineered for Adrenaline

The beauty of outdoor exploration lies in the unknown. But the hidden risks behind that unknown can’t be ignored.

CO and CO₂ levels can rise anywhere, yet the danger increases dramatically when exploring the outdoors where smaller living spaces like tents, vans, and huts trap air far more quickly than we realise. At the same time, adventurers face a long list of other challenges: darkness, shifting temperatures, rising humidity, unpredictable weather, and unfamiliar environments.

And yet, most traditional monitoring devices simply aren’t built for this reality. Some only measure basic temperature and humidity. Others are bulky and heavy - the kind of equipment that feels like a brick in your pack. Very few offer the essential combination of lighting, portability, multi-gas detection, and environmental awareness that outdoor safety truly requires.

For the past five years, our team has been dedicated to solving this gap. We’ve immersed ourselves in the world of outdoor living - interviewing over 200 experienced adventurers, camping creators, foresters, geologists, and field workers across multiple regions. Their needs were remarkably consistent, and their frustrations clear:

We took this feedback and engineered an all-in-one solution designed specifically for the realities of the outdoors: The Fabisense Mars
