Protect yourself from an invisible danger.

The Radiant CO-Pocket™ is a fast, reliable carbon monoxide detector in a rechargeable, pocket-sized, self-contained unit, designed specifically for aviation.
 
It alerts at the FAA-recommended 41 PPM level with buzzer, audible alarm, and bright red strobe alarm, mirroring the trusted logic of Radiant’s CO-USB line. About the size of a flight timer, the CO-Pocket fits in a pocket, hangs from a lanyard, or mounts to a panel.
 
It has a USB-C charging port, with a standard USB-A to USB-C charging cable included. If you need USB-C to USB-C cable they are easily available at other retailers.
 
The unit runs up to six months on a single USB charge, displays CO level, temperature, and humidity, and can be zeroed to clean air for long-term accuracy.

To Our Customers

We are in the business of offering innovative aircraft instruments for experimental aircraft flying, and backup / CO instruments for general aviation (non-TSO/non-PMA). The instruments from Radiant Technology are not designed to be used in applications where their failure would endanger safe flight or human life in any way. They are intended solely for use in VFR conditions. They are not certified to meet any Technical Standard Order, and are not produced under a Parts Manufacturing Authority (TSO / PMA). As a result, they are suitable only for use in experimental and ultralight aircraft, and in Light Sport Aircraft, if meeting the requirements of the respective manufacture.

Support

If you need support for your Radiant instrument purchase, please contact us by email at support@radiantinstruments.com. Because of our small staff, we do not have a direct phone number.  We do our best to respond to emails as soon as possible. If you do not hear from us within 48 hours, please try again. You may also try kathy@radiantinstruments.com. Please check our our Warranty Information here.

Shipping Information

Since we offer innovative aircraft instruments, we often introduce new products for sale that are in the final engineering phase. Sometimes an engineering problem emerges in the final phase that delays our production runs. This means that if you are ordering a new product, we could be several weeks out from shipping. We try to keep our product pages up to date with shipping information.

​

As of 2025, there are only two of us working Radiant instruments. We manufacture products in batches, and cycles take about a month. It is always best to order now and get on the list. We do charge your card at the time your order is placed.

 

We are now able to offer 2nd day UPS shipping on domestic orders, as well as USPS Ground Advantage. In some cases, we may need to revise you shipping amount, and will notify you by email of that change.
