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.

Performs as expected. In a 10 hour round trip flight, had one disconnect. Could have been user error.

Could’t Be happier with my Sentry
I fly frequently in aircraft with Stratus 2S recievers on board and was looking for something to purchase for use in the non-equipped aircraft I fly. I liked the Sentry’s features, smaller size and longer battery life so I decided to go with it. I couldn’t be happier with it’s performance. I’ve flown over 30 hours with it on trips in Southern California in the last 10 days. The data and graphics were every bit as good as the Stratus 2S. I could highly recommend the Sentry to someone in the market.

Best purchase in years
As a true Foreflight fan this is the best tool for situational awareness. During pattern work it was great to locate other aircraft that reported generic location (South of airport) when they showed on the iPad as Southeast. My tracklog was spot-on based on the built-in GPS. Unit is mounted Vertical in right rear window of Cherokee 140

Easy Setup
This worked right out of the box with minimal fuss. Tried it first in my kitchen window, received one tower and was tracking planes in flight as well as radar. Finally flew with it over Labor Day Weekend, the mount is solid, and the signal was great throughout the flight.

Lousy customer support from ForeFlight
The device is excellent but customer support at ForeFlight is woefully inept. I’ve been trying for almost a month to link Sentry to a new iPad. No joy and ForeFlight ignores my email requests for assistance. I regret having been loyal to ForeFlight after several years when I could have bought the Stratus from Sportys at the same price point.

Flawless incorporation with foreflight. ADS-B display is easy to read. Highly recommend this product.

Excellent Unit / CO Detector Alarm could be louder
Really like the compact size, easy of use and setup (nothing really to do), long battery life, good/fast ADS-B and GPS reception, easy mounting, Foreflight connection fast, AHRS feature works well, great price point. My only nit pick is the volume of the CO alarm - I do not think it is loud enough in piston aircraft especially as most pilots wear headsets (many of them noise cancelling). I raised this with Foreflight and they immediately had uAvionics send me a replacement to see if my unit was defective, but the volume was the same. Nevertheless, my overall initial experience is very positive. I give it 4.5 stars; if CO alarm volume was louder it would be 5 stars.

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
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.
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.
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 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.
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.
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
