Does everything exactly as advertised. Provides traffic, weather, built in CO detector and AHRS. Having used a Stratus 2s, I am very pleased with the Sentry. Both products (Sentry and Stratus) are high quality, but the the lower price and smaller form factor of the Sentry make it a clear choice. I highly recommend the Sentry to anyone looking for a high quality ADSB receiver.November 13, 2018Purchased
2 weeks agoDurability3 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5Would You Recommend?YesSmall cheap AHARS ADS-B and CO with 12 hour battery??? No brainer, take my money already!!!Great little unit. I was looking for a backup ADS-B/AHARS unit for the G-345 and I hate those little plastic CO detectors, and this little unit fixes both issues with one small box! Great battery life too, but like the original Stratus2, I hate the color.November 8, 2018Purchased

I put it off for months questioning whether I should spend the money or not well I wish now I would have bought months ago! Love foreflight and this just makes it even better!November 8, 2018Purchased

1 month agoDurability5 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5Would You Recommend?YesAbsolutely Great DeviceI was looking for a device that would provide be with traffic info and better situational awareness. Could not have chosen a better device. Has already alerted me to traffic I would have had great difficulty noticing even with a proper scan. Could not be easier to use. Have not yet seen weather reported on this device but looking forward to seeing that feature. Definitely worth the investmentOctober 25, 2018Purchased
1 month agoWould You Recommend?YesGreat addition to the cockpit at a great valueThe Sentry has been a great addition to my IFR flying. The ADS-B traffic and weather has come in handy a few times already. Helped me to divert around weather and see traffic before ATC did. Another good feature is the glide distance calculation which is always good to know just how far it is from any airport should the need arise. My CFI is super jealous and wants one for himself. Works flawlessly with ForeFlight as well.October 23, 2018Purchased

1 month 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 month 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

- Question and Answer
Browse 30 questions Browse 30 questions and 32 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 checkwhat 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.Is 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 it work on an Iphone instead of an iPad?BEST ANSWER: Yes, Foreflight will work on an iPhone and the Sentry will provide data.Can I use this item in Slovenia ( Europa )?BEST ANSWER: It would be used only as a GPS. You would notWill 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.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?
