2 weeks agoDurability5 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5Would You Recommend?YesImpressiveI spent some time debating between the Sentry and the Stratus and, after some extensive research figuring out the differences between the two, took the plunge on the Sentry. For those, like me, who were wondering exactly why the Sentry is $200 cheaper, it's because 1) the Sentry will only work with Foreflight and 2) the Sentry lacks the external antenna connections. If, also like me, you use Foreflight and have no need for external antenna connections, save the $200 and go with the Sentry. Every other feature advertised with the Stratus is offered in the Sentry, including all FIS-B weather, dual-band traffic, WAAS GPS, and customizable WiFi settings. In addition, the Sentry includes a quality, sturdy-sided carrying that holds the Sentry, the Ram Mount, and spare cables.
Setup with the Sentry is a breeze and it connected immediately without any problems to Foreflight. I was skeptical about the 12 hour battery life, so I tested it by connecting to my iPad running Foreflight with the Sentry in my office window. After 11 hours and 20 minutes of uninterrupted operation, the Sentry finally shutdown. During the entire time, I was receiving UAT and 1090 traffic as well as GPS. It never once disconnected from Foreflight. The only thing that didn't happen was a shortcoming with Foreflight, not the Sentry. Specifically, while Foreflight warned me when the Sentry battery was at 20%, it never announced that it had disconnected. Otherwise, everything went exactly as it was supposed to.
Ultimately, if you need to use apps other than Foreflight or need to be able to connect external antennae, then the Stratus may be required. But, if not not, the Sentry is a excellent product at a great price point.October 16, 2018Purchased
1 week agoMuch better value than other optionsI’ve considered the Stratus for a couple years, but the price seemed way out of sorts with the hardware, should have been ~$400. When Scout came out last year, I seriously considered it. The lack of GPS didn’t bug me, I had GPS in my iPad. The AHRS was a bigger concern, but the lack of battery ended up being the blocker for me as running a cable to an external battery or power outlet seemed like too much clutter in the cockpit. When the Stratus 3 came out with the better price, I thought maybe they realized they had to come in lower (Still $300 above where I thought it should be). When Sentry came out around the same time and still undercut it by $200, had 50% more battery life and included a CO sensor, plus was smaller I was sold. In the plane, performance has been great. No problem getting weather and traffic. Flying near the NYC Bravo, the extra view of traffic is great & I love weather reports before picking up ATIS. At $500, it’s a 4 star, drop another $100 and it’d be 5.October 14, 2018Purchased

Only used once so far and only did pattern work so didn't do much (anything) with wx but will update my review when I have. Did see plenty of aircraft notifications though. GPS is slightly less accurate than my Dual 160. Tracking/Logging seems to work just as it should.
Space saer combined with CO monitor. I'm now able to get rid of my homebuilt 'stratux' and my Dual GPS. Those will be going up for sale!

1 month agoWould You Recommend?YesCould’t Be happier with my SentryI 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.September 14, 2018Purchased

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 140September 5, 2018Purchased

- Question and Answer
Browse 28 questions Browse 28 questions and 30 answersWhat’s the difference between this device and stratus 3?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?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?BEST ANSWER: Not sure about the GPS or the new frequencies. Will have to checkIs the weather resolution the same as an XM weather unit?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?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.Will the sentry pick up lightning and echo tops?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?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?BEST ANSWER: No, just the WiFi is required.Can it be connected to Android devices?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?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?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.BEST ANSWER: It will fully function and operate while being charged, just tested this out in flight recently.Can I used with my iPad?BEST ANSWER: Yes, it works with the iPad and ForeFlight.Will the Stratus 3 or Sentry work with heated windows on corporate aircraft?ForeFlight Sentry ADS-B ReceiverBEST 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?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?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.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?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?BEST ANSWER: No, the Stratus app will not work with this device.Can this unit be operated while being charged in the cock pit?BEST ANSWER: Yes, it can be charged in the cockpit.Do you have a payment plan?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?
