The Shield USB 6.0 builds on the legacy of the Shield 4.0 using the same technology in a smaller form factor, based on years of improvements inspired by customer feedback. The 6.0 is the first of its kind – a small USB stick that plugs into any USB source for an extremely simple, portable, and functional solution for sensitive carbon monoxide detection in your aircraft. It measures a compact 2.5″ x 1.5″ x 0.75″ and weighs a mere 0.7 oz.
CARBON MONOXIDE SENSITIVITY
The Shield 6.0 features the same 30-second up and down response to carbon monoxide with 1 ppm resolution and +/- 15% accuracy. The 6.0 is temperature-independent with an internal temperature adjustment circuit that compensates for temperature-induced errors in the sensor between -10 C to +50°C. The state-of-the-art solid sensor requires no recalibration for at least 10 years under normal operating conditions and is completely unaffected by pressure and altitude changes.
BUILT-IN LIGHT INDICATORS
The hardened glass cover features a glowing ‘A’ logo of blue, amber, or red to visually indicate carbon monoxide ranges, controllable in modes of pulse/off/steady via the Aithre Connect application.
AITHRE CONNECT iOS APP
The Shield 6.0 is fully supported in the Aithre Connect App available on the APPLE store, providing discrete and 4-hr history trend data plus popup and Siri notifications to your headset (when paired) when threshold CO levels are crossed. You can set your custom warning level or depend upon the built-in 2 ppm, 10 ppm, and 50 ppm warning levels. Additionally, you can see trend data plotted vs. airspeed, altitude, and temperature to determine relationships in carbon monoxide levels. In the event carbon monoxide levels are detected, you will appreciate access to all your trip data stored on your iOS device automatically as a CSV file.
NO BATTERY – NO CHARGING
The Shield 6.0 operates by simply plugging into any USB power source. This can be a USB charger or a panel mounted USB plug. Even your computer can be used as the USB plug. No batteries or recharging is ever required in the Shield 6.0 device itself.
CLIP MOUNTED OPTION
Many customers enjoy the clip mount that made the Shield 4.0 predecessor popular. This same clip mount system is possible with the Shield 6.0 and two clips are provided for use in various settings like your hangar and airplane. When clip mounted, the 6.0 uses the included female-to-male USB extension wire to plug into your USB power source.

Our Office Location
4753 E. Falcon Drive, Suite #3
Mesa, AZ 85215
We operate out of a private hangar with limited public access. Simply call our office at (480) 300-3050 upon arrival so we may meet you for your appointment. Thank you for choosing Airplane Caretaker!

For aircraft with accessible exterior piano-style hinges, we apply a thin coat of Tri-Flow or LPS-2 (Owner’s choice).
We lubricate landing gear oleo struts with StrutWipe, a product designed specifically to both clean and lightly lubricate the exposed chrome surface, removing dirt, bugs, and moisture which could damage seals or cause pitting and corrosion over time. StrutWipes are presoaked in MIL-PRF-5606.

Where space and safety margins allow, your aircraft may be repositioned slightly fore or aft to relieve tire pressure points. This helps reduce tire flat spots and unnecessary vibrations during taxi or takeoff on your next flight. Wheel chocks are reset to secure the new position prior to moving, and if safe repositioning isn’t assured, your aircraft remains in place.

The average General Aviation airplane is now over 50 years old, and like classic cars, age and inactivity take a toll. With an experienced eye helping look things over, some issues can be caught early—potentially handled before your next flight.
Since many owners fly only once or twice a month—or even less—Airplane Caretaker becomes an essential partner in monitoring your aircraft’s status and condition between flights. When your airplane has something to tell you, but you’re not nearby to hear it, we’re available to help bridge the gap.
