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.

Great Except the the Mount
I am pleased with the Sentry and would have given it 5 stars except for the mount. It is huge and so powerful that it sucks a dent in the side windows of my Cessna 140. I am concerned that if I leave the mount in the plane it would set up a permanent dent....especially in hot weather.

Otherwise, the Sentry works great. I’ve flown with it for about 9 hours since I got it and the signal dropped only once. Perhaps from the placement of the unit? I’ve moved it since then and no issues.

The AHRS system is a nice backup to have if I ever get myself in a bind. Getting the attitude set prior to takeoff in a tailwheel airplane can be a bit difficult. I set mine at 10 degree pitch up and that gets me close. But, I don’t ever expect to takeoff into IMC so not an issue.

Battery life is good. I was down to 80% after a 3 hr flight. Charges quick.

Aside from the mount, the unit is compact and light. Not too intrusive on the appearance of my 73 year old airplane.

Small, lightweight with a 12 hour battery and considerably less expensive than its nearest competitor.
I’m using my Sentry in a 1941 Interstate Cadet and a 1940 de Havilland Tiger Moth. Works very well and I’m planning on using it on a long cross country from Indianapolis to Ocean City, Maryland.

Happy with my purchase
Have owned my Foreflight Sentry for just over a month. I’ve used it about 20 hours on 10 flights, in 5 different aircraft with no issues. I’m very pleased with the performance, compact size, capabilities, and liked that it also included a RAM mount and carry case, unlike Stratus. The Sentry ABS-B appears to be more sensitive than the Stratus 3 I returned. At times Sentry displayed aircraft that the Stratus delayed to show, or, did not show at all. I also had a CO carbon monoxide alert on climb-out that I squawked. It will be interesting to hear back what the mechanics found. All-in-all a great product that I would not fly without.
I would add that the Sentry plastic housing appears a little flimsy, like it would not do well if dropped and the on-off button feels cheap. I would also like to see more detailed explanations in the owners manual and “Made in USA” markings on the product.

worked great out of box on long cross-country
After my Stratux failed for a second time (bad connection between battery and box), I decided to purchased a Sentry. I bought the Sentry at Sporty's and used it from the box on a five-hour journey home. No issues at all. No ownship ghost images and the AHRS set-up was automatic and worked great. Because it is brand new, I can't comment on the durability or reliability, but so far so good!

Bought in December 2019
Well, the unit refuses to turn on unless it's plugged into a charger. I reached out to Foreflight and they were responsive. My request for help was passed on to three different people at Foreflight, then I got an email telling me they were forwarding my email to uAvonics. I've used this device about 4 times (total of less than 2 hours) and it's already failed. It's difficult to actually recommend buying a device that costs this much yet fails after less than 2 hours of real use.

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.
How long does the CO sensor last and do I have to service it once a year?
Andy K on Mar 16, 2020
BEST ANSWER: The sensor does not need service. It is good for 10 years.
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.
Can the unit be mounted upside down? Foreflight appears to have three mounting settings for it, and the one that's not on a side window appears to be right-side-up on the glare shield. Suction cup upside down from the center of the windshield between the sun shades would be an ideal, out of the way location in my plane. But curious if Foreflight will accommodate this orientation.
Chris on Nov 29, 2018
BEST ANSWER: Yes, I connected my iPad to the sentry with the unit upside down. Make sure to mount the unit then turn it on so that the Sentry can calibrate.
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 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 PRODUCT COMES WITH A MOUNT ?
A shopper on Jul 23, 2018
BEST ANSWER: Yes, it has a suction cup mount.
Does this only work with fore flight?
Evert O on Jul 23, 2018
BEST ANSWER: Yes, it only works with ForeFlight.
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.
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 but remember it does not provide internet access (WiFi is just for short range data transmission).
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.
Can/will you ship the Foreflight Sentry (with lithium battery) to Alaska?
A shopper on Aug 13, 2018
BEST ANSWER: Yes, we can send it via UPS. We can not send it via the Postal system.
Can this unit be operated while being charged in the cock pit?
Todd L on Jul 30, 2018
BEST ANSWER: Yes, it can be charged in the cockpit.
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.
Had an issue with a new Sentry. Received it and connected to iPad and all good. Worked fine and saw SW flight flying overhead. Plugged in iPad charger overnight and blue light was on and then off in the morning so fully charged. Took it to the aircraft and problems. First, I pressed the power button to turn on and all good, but it would not shut down. Pushed and pushed and nothing. Also, while it connected to the same iPad yesterday, today nothing. I contacted FF and one of the techs suggested that I could have overcharged and messed up the BMS...battery management system. I used my normal Apple iPad usb charging block. Does this sound possible or did I just get a bad unit? Anyone know what the specific charging voltage should be. I thought USB C’s were 3 volts, but not sure. Thanks
David K on Jun 18, 2019
BEST ANSWER: Sounds as if the unit is defective. Please return it to us.
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.
When will this item be back in stock?
Rochelle P on May 30, 2020
BEST ANSWER: We expect to have this back in stock on June 6th, 2020
So, do I understand correctly that the sentry will not work if you loose a wifi connection?
Taylor W on Apr 29, 2020
BEST ANSWER: The Sentry connects via WiFi so if the connection is lost it will not provide information to the iPad. But remember WiFi is short range from the Sentry to the iPad, it does not require a cell/data connection.
Is the traffic and weather available in Canada?
Joseph B on Apr 3, 2020
BEST ANSWER: No, it is not.
Is the gps in your phone the same strength as the gps in this device?
Joseph B on Apr 2, 2020
BEST ANSWER: No it is not. The GPs in Sentry is a WAAS GPS.
One review mentioned not being able to use his devices cell signal (LTE) while connected to the Sentry. Is that correct?
swtbabyjesus on Mar 16, 2020
BEST ANSWER: With the current IOS you are able to run another app that can use the cell service. Foreflight is not able to use the cell service and be connected to the sentry. .
I run Fore Flight full subscription with an I pad with its on network card, form what i understand I would be getting traffic and CO detection as additional features correct?
also does this work in Canada
ken s on Mar 16, 2020
BEST ANSWER: With the Sentry you will receive Traffic and CO detection. To receive Canada plates and maps you have to have a subscription for Canada.
Compatible with aerovie?
A shopper on Mar 16, 2020
