ADS-B receiver with CO detector

Sentry is a compact, affordable ADS-B receiver specifically made for ForeFlight. In addition to popular features like ADS-B weather and traffic, Sentry also includes a carbon monoxide detector to warn of dangerous conditions in the cockpit. No larger than a deck of cards, Sentry packs long list of features into a small size, but still offers 12 hours of battery life.

Features:

  • Subscription-free weather in flight
  • Dual band ADS-B traffic
  • Built-in GPS
  • Backup attitude information (AHRS)
  • Carbon monoxide alarm
  • Pressure altitude sensor
  • Weather replay
  • 12-hour battery
  • Connect to ForeFlight via WiFi (5 devices)

Integrated Weather Replay

With onboard memory supporting up to 30 minutes of FIS-B data, Sentry saves animated radar and other weather so data is available as soon as you connect. Turn off your iPad screen and save battery when not in use.

Carbon Monoxide Detector

A first for portable ADS-B receivers, Sentry provides a built-in carbon monoxide sensor and alerting system, with an audio and in-app alert when CO concentration reaches hazardous levels. The LED indicator also provides a visual indication of CO levels.

Synthetic Vision

ForeFlight Synthetic Vision provides a backup glass cockpit on your iPad that can help you stay aware of your position and surroundings in normal and emergency operations. Combined with Sentry, Synthetic Vision provides super responsive pitch and bank in addition to terrain and obstacle depictions. Simple calibration supports mounting Sentry on the left window, dash, or right window.

12 Hour Battery Life

Sentry’s efficient power usage allows 12 hours of continuous operation on a single charge, providing non-stop situational awareness for the long haul. Recharges using included USB-C cable.

Fast & Reliable Mounting with Quick Release

Sentry’s quick release mechanism means you can attach and remove it in under a second. The popular RAM® suction cup mount ensures a long-lasting seal and high heat tolerance so you can leave it in the plane between flights.

Compact Form Factor

If you’ve got room for a deck of cards in your aircraft, you’ve got room for Sentry. Large enough to not get lost under the seat, yet small enough that it doesn’t block your view, and the internal battery makes charging simple and straightforward. Measures 2.25”w x 3.25”l x 1.25”d.

Easy Firmware Updates Through ForeFlight

Updating Sentry’s firmware is a non-issue thanks to fast over-the-air updates through ForeFlight. When an update is available, ForeFlight provides one-tap installation that finishes in seconds.

In the box:

 
Note: Requires ForeFlight version 10.2 or higher.

Not the quality product that I would expect from ForeFlight.
This product constantly disconnects in flight. In looking back at other reviews for this unit, I can see 7 other reviews since 2018 complaining of the same issue. I don’t understand how this isn’t fixed yet. Does uAvionix not complete a rigorous user acceptance test before delivering the product to customers? If you need GPS and or traffic just for fun, this unit is ok. But if you are using it to watch out for other traffic or want a flight path to show your students in a debrief, spend the extra money and get a Stratus 3.

Used the ADS-B Receiver for the first time this weekend. We flew into the Downtown Kansas City airport that was very busy at the time. The Receiver worked perfectly and allowed us to see traffic that we were unable to see looking out the cockpit. Very pleased with the Receiver.

Just flew our new plane from Tulsa to Oxford, CT. We had a Cessna fly right over us that we only knew was there thanks to the Sentry! Paid for itself right then. Also amazing to see departure/arrival routes passing Cincinnati and New York’s class B airspace.

Product Review ForeFlight SENTRY
SENTRY disconnects from ForeFlight. This is a known bug confirmed by the manufacturer who said they are working on a fix.
When fully charged, the SENTRY battery never shows greater than a 95% charge level in ForeFlight.
No country of origin markings noted anywhere on the product or any of the packaging.
Instruction manual is bare bones, more like a quick start guide, and lacks detailed instructions and explanations.
A SENTRY product specification sheet is not available. This was confirmed by the manufacturer.
Case does not seem durable. On-off button feels cheap.
The window mount, protective case, and charge cable are great.

Best Pilot's help for small aircraft
I used it the moment I recieved it. The Sentry is an amazing tool for all pilots that have don't have aircraft with the capability of getting weather and any related information from their basic avionics on dashboard. Its small, portable and relays all info to the ipad. It's beyond my expectations. Recommended !!!

Impressive little device!
Has performed flawlessly so far. Battery life appears to be as claimed, having gone down 50% in 6 hours of flying. Mount is very convenient and secure. A huge improvement over my old receiver.

What’s the difference between this device and stratus 3?
A shopper on Jul 26, 2018
BEST ANSWER: The Sentry has no external antenna connections, a longer battery life of 12 hours and a CO detector. The Stratus 3 has flight data recording, external antenna connections, and is capable of working with apps other than ForeFlight.
Are there any feature/function comparisons with the Stratus 2S and 3?
A shopper on Jul 25, 2019
ForeFlight Sentry ADS-B Receiver
ForeFlight Sentry ADS-B Receiver
Stratus 3 ADS-B Receiver
Stratus 3 ADS-B Receiver
ForeFlight Sentry Mini ADS-B Receiver
ForeFlight Sentry Mini ADS-B Receiver
BEST ANSWER: Stratus 3, 8-hour battery, GPS, ADS-B in and AHARS
Sentry 12-hour battery, GPS, ADS-B in and AHARS
Sentry mini must provide a power source, Provides GPS and ADS-B in.
Other than the CO2 monitor, what is the primary difference between this and the scout which costs less than half of what this unit retails for?
Scott E on Jul 23, 2018
BEST ANSWER: Scout does not have a built in GPS, battery, or AHRS for backup attitude. It only does ADS-B.
Does this support GLONASS or only GPS? Also what about the new GPS frequencies that are coming online L2 and L5?
A shopper on Jul 23, 2018
BEST ANSWER: Yes it does both GPS (WAAS) and GLONASS.
Are there any altitude or line of sight limitations for using Sentry?
Charles on Mar 27, 2019
BEST ANSWER: Like all ADS-B receivers, you'll need to be in flight to get reception most of the time. Coverage is quite good above about 1500 ft. AGL, but like VOR the reception does depend on line of sight.
what is the benefit of the stratus 3 having an external antenna port and the Sentry not having one? What exactly does the external antenna do?
A shopper on Sep 12, 2018
BEST ANSWER: It just offers more options for mounting - you could mount the Stratus semi-permanently under the panel or in the back of the airplane, and use an external antenna to maintain good reception. The other benefit would be in areas of marginal ADS-B coverage, where that antenna improves reception. However, most of the time it's not a big issue.
DOES THIS PRODUCT COMES WITH A MOUNT ?
A shopper on Jul 23, 2018
BEST ANSWER: Yes, it has a suction cup mount.
After 5 hours charging the pwr light is blue not green. This normal?
Neil T on Aug 16, 2018
BEST ANSWER: My initial charge took longer than 10-15 minutes. But honestly I don't recall the total time. If you leave it on the charger the unit will shut the lights down when fully charged. Blue light while charging. Disconnect the power and turn the unit on it will display level of charge via light colors.
Will this unit function normally in flight while charging? Such as forgetting to charge before a flight and don’t have time to charge prior to departure.
A shopper on Sep 4, 2018
BEST ANSWER: It will fully function and operate while being charged, just tested this out in flight recently.
Can I Use this item in Japan?
A shopper on Aug 2, 2018
BEST ANSWER: Yes, the Sentry can be used world wide. The FIS-B functionality will only work in the US and UK but all other functionality will be supported world wide. You'll still have GPS, CO monitor, ADS-B Traffic reception, and AHRS regardless of location.
Is the weather resolution the same as an XM weather unit?
A shopper on Aug 14, 2018
BEST ANSWER: For the most part it's the same, except that ADS-B radar only shows good resolution within about 150-250 miles of your airplane. SiriusXM weather is full resolution nationwide. So if you're comparing radar at long distance, the ADS-B will be noticeably blockier.
Does the Sentry have the "Smart Wi-Fi" feature like the Status 3? "Smart WiFi - use your iPad’s LTE connection while connected to Stratus 3"
Russell F on Jul 28, 2018
BEST ANSWER: "Smart Wi-Fi" feature will available in the future app update.
Does this only work with fore flight?
Evert O on Jul 23, 2018
BEST ANSWER: Yes, it only works with ForeFlight.
I lose wifi all the time when I fly? Does anyone else lose wifi when crossing borders or going past 10500
A shopper on Aug 22, 2019
BEST ANSWER: I was having the same problem with my Sentry. I called the manufacturer directly and spoke with their technical support. I was advised that my device required a firmware update to resolve the issue. That seems to have corrected the problem. Good luck!
I understand it is ForeFlight only....my company uses jepp FD Pro x.....can i switch back and forth from foreflight ADSB and Jepp FD Pro location service seamlessly?
A shopper on Jan 5, 2020
BEST ANSWER: No it will not. The GPS is not shared via location services in iOS, so all of the features are limited to ForeFlight.
Can I Use this item in Europe : France and Switzerland ?
A shopper on May 29, 2019
BEST ANSWER: The Sentry will perform ONLY as a GPS, AHRS and CO detector. ADS-B weather is not available outside the US.
Does it have flight recording capability as with the Stratus?
A shopper on Jul 25, 2018
BEST ANSWER: It is possible but I have not heard of any mention of that either. Please watch our website.
Is the unit reliable in business jets above 18,000 feet?
A shopper on Feb 22, 2020
BEST ANSWER: Yes it is.
When I connect with my Cellular iPad, it loses internet due to the the Is there a setting that I can still have access to the internet over cellular while connecting to the Sentry? because now once I connect to Sentry I lose internet.
A shopper on Feb 18, 2020

I asked the previous question - so hypothetically a passenger could use this same WiFi in flight on their phone or tablet?
A shopper on Jan 30, 2020
BEST ANSWER: Yes, you can connect up to five devices to one Sentry.
So this device actually produces a WiFi signal - I have ForeFlight on a non-cellular iPad mini - no other WiFi in the plane - my G335 transponder only does ADSB out?
A shopper on Jan 30, 2020
BEST ANSWER: Yes, you can use this with the WiFi only iPad. It provides ADS-B in.
I understand if I use this in Europe (stationed here right now, should be back in the US in 1.5 years or less) it will not receive FIS weather, but will it show ADS-B traffic as it uses standard frequencies?
A shopper on Jan 28, 2020
BEST ANSWER: It should show the traffic if transmitting on 978 or 1090 Mhz.

A shopper on Jan 3, 2020
BEST ANSWER: -4 to 113F
-20C to 45C

A shopper on Jan 3, 2020
BEST ANSWER: The US
Does this unit do adsb out?
Doug S on Dec 31, 2019
BEST ANSWER: No, this is an ADS-B IN only device.
I used this device on a recent trip coupled to my IPAD and using Foreflight. I have a Cirrus SR-20 with Perspective avionics and got a Data mismatch and cross talk error on my perspective PFD. Does this device when used with Foreflight and coupled via FLIGHTSTREAM introduce errors with the GARMIN 1000 avionics?
Steve W on Dec 27, 2019
BEST ANSWER: Sentry plays well with GARMIN. These are GARMIN messages that normally appear when you load a new Nav database before the expiration date of the old one. The G1000 sees both databases and tells you that there is a mismatch. Call the friendly folks at GARMIN tech support and they’ll help you sort it out.
Can this connect to an iPad that is WiFi only?
A shopper on Dec 21, 2019
BEST ANSWER: Yes, the Sentry produces a Wifi signal that the iPad will connect to.
Is this 2020 compliant?
A shopper on Dec 14, 2019
BEST ANSWER: No, This is an "IN" receiver to be compliant you must have an "OUT" transmitter.
