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:

  • Sentry
  • Charging cable (no plug)
  • Suction cup mount
  • Rugged carrying case
  • Quick start guide
 
Note: Requires ForeFlight version 10.2 or higher.

I doesn’t always want to recalibrate and I need to do this each time a fly because I use it in different aircraft. The synthetic vision works fine some days and doesn’t on others. The ADS-B in works great always. The airspeed and altimeter do not always show. Sometimes they are on screen and other times they are not.I’m still undecided if I would buy again.

New Sentry - First Use
I used my new Sentry ADS-B in receiver on a 2-day ferry trip for the first time and it worked well.

The only issue I had is when I just put the white block in my flight bag without being in its very nice case, the power on button can be activated easily touching other items and when I took it out to mount it, it was warm to the touch. I did run USB power to it for the entire flight since I could not trust the remaining battery life. I will place a hard piece of cardboard or thin plastic over the flush button and wrap it with a rubber band.

Sporty’s, Foreflight and Sentry
I am using this in conjunction with Foreflight and synthetic vision in my Super Stol. Easy setup and excellent performance with iPad mini4, 9.7” iPad and iPhone 8. A wonderful way to have a full performance avionics suite for $499. You will not be disappointed with the sentry or Sporty’s customer service.

Got this device for Christmas. So far - very impressed. Very easy set up with ForeFlight, and impressive performance. Only think I have not yet figured out is how to get pressure altitude working - but GPS altitude and AHRS impressive

Restart Required on All Flights So Far
The AHRS rarely works on startup. Once I am in flight and level I have to restart the Sentry to get the AHRS to work at all. At startup and until I restart the Sentry I just get “No Attitude Information Available”. Everything else works fine. I love the smaller size compared to my previous solution. Battery life is excellent. The RAM window mount included works great. If I could just remember to restart and check the Sentry prior to takeoff all would be great.

Mostly great
The Sentry is fantastic with one minor exception: electrically heated windows. I’m 100% happy with it in all the smaller GA airplanes I fly, but it is unable to receive any signal trough the heated windscreen on the G650. When mounted on the heated side window in the crew rest area, it’s better, but still doesn’t get great ADS tower coverage.

Amazing device a must have
My fiance bought this for me as a chritmas present. Amazing device, easy to use. Easy to hook up with foreflight. It does everything for you. GPS, traffic info and backup attitude. Works right of the box It picks up the signal great. The adsb is not working yet. Im waiting to take it up to see. Im guessing the reason why it hasnt pick up the adsb signal is because i probably too far away from a ADSB tower. Plus the instruction says ADSB ground station will not be available until airborne at around 1000 AGL. The value of this device is great also it has alot for 499. I would highly recommend. Must have trully

Great Device & Fantastic Value vs. Stratus
Picked up a ton of aircraft outside of KORD from the ground. ForeFlight integration is incredibly simple. No complaints.

I’ve played around with Stratus 1S, 2S, & 3, as well as Startux. I would say that Sentry is by far the best value and its incredibly simple to get started, don’t need a bunch of antenna’s or extra connections to make it work. I will be keeping it!

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.
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: Not sure about the GPS or the new frequencies. Will have to check
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.
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.
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 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.
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.
Does it come with a mounting device like a suction cup?
Don R on Dec 31, 2018
BEST ANSWER: Yes, this included the suction cup.
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.
I love the integrated CO monitor, but electronic CO monitors usually have a life of 5-7 years. Does this have an EOF for the CO monitor?
Paul P on Nov 21, 2018
BEST ANSWER: The manufacturer does not list an end of life for this unit.
Will it work on an Iphone instead of an iPad?
A shopper on Nov 10, 2018
BEST ANSWER: Yes, Foreflight will work on an iPhone and the Sentry will provide data.
Can I use this item in Slovenia ( Europa )?
Slavko K on Nov 8, 2018
BEST ANSWER: It would be used only as a GPS. You would not
Will the sentry pick up lightning and echo tops?
A shopper on Oct 3, 2018
BEST ANSWER: It will when products are broadcast over the ads-b system.
Do I need the foreflight synthetic vision for backup-attitude, or is (pure) attitude provided in the basic foreflight package?
bergfalke on Sep 24, 2018
BEST ANSWER: Yes, you should be able to use the AHRS without the Synthetic vision.
Do I need wifi plus cellular on my iPad for full functionality?
Mike P on Sep 14, 2018
BEST ANSWER: No, just the WiFi is required.
Can it be connected to Android devices?
Mike P on Sep 14, 2018
BEST ANSWER: No, the Sentry is an IOS exclusive product.
Does it work with other EFB's besides Foreflight?
A shopper on Sep 6, 2018
BEST ANSWER: No it does not.
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 used with my iPad?
Baker on Aug 25, 2018
BEST ANSWER: Yes, it works with the iPad and ForeFlight.
Will the Stratus 3 or Sentry work with heated windows on corporate aircraft?
Russ S on Aug 22, 2018
ForeFlight Sentry ADS-B Receiver
ForeFlight Sentry ADS-B Receiver
Stratus 3 ADS-B Receiver
Stratus 3 ADS-B Receiver
BEST ANSWER: The heated windows present a problem for the reception with both units, although in most cases they will work. For particularly thick windsheilds (Learjets, for example) an external antenna may be required. The Stratus includes ports for an external GPS and ADS-B antenna, while Sentry does not. I would recommend the Stratus if you're concerned about it.
Does anyone know if this unit also receives and shows air traffic as part of its presentation?
Richard on Aug 16, 2018
BEST ANSWER: Yes it is a dual band (1090 and 978 MHz) receiver, so it will receive ADS-B traffic. Note that this can be limited unless your airplane has ADS-B Out. Details in this article: https://ipadpilotnews.com/2016/01/ads-b-traffic-101-2/
Hi. I am not sure if I understood it correctly. Is it portable datalink or does it only store the weather information downloaded on the ground? Than it would be useless... Maybe the stupid question from me. However, if it is a portable datalink, which downloads the weather information dirung the flight and than shares with your iPad, does it work also in Europe? How old can be the frames maximum? Ive heart that sometime datalink shares even 20 minutes old weather information which makes it pretty useless in changing weather. How is downloading of the data charged? Thank you for answers.
Martin K on Aug 15, 2018
BEST ANSWER: This receiver is an ADS-B receiver. The weather information is broadcast from ground stations here in the US. The weather received is between 5-7 minutes old. The data is not downloaded. When received by the receiver it is sent via a WiFi signal to the iPad to be displayed on Foreflight.
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.
Will the AHRS in this device work with the AHRS app for an iPhone 6s without Foreflight?
A shopper on Jul 30, 2018
BEST ANSWER: No, the Stratus app will not work with this device.
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.
Do you have a payment plan?
Gautam B on Jul 29, 2018
BEST ANSWER: You can choose a payment plan when paying with PayPal at checkout.
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.
Who makes the unit?
Ralph H on Jul 28, 2018
BEST ANSWER: uAvionix makes it for ForeFlight.
What's the difference between Sentry and Stratus 3? Which is better?
A shopper on Jul 26, 2018
BEST ANSWER: Reply | Flag for CS | Optout | Go to Answer | Edit | Attach itemsThe Sentry has no external antenna connections, a longer battery life of 12 hours and a CO detector.
