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.June 1, 2020Purchased
2 weeks agoPerformance5 / 5Ease Of Use5 / 5Value3 / 5Would You Recommend?YesSmall, 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.May 28, 2020Purchased
2 weeks agoDurability3 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value4 / 5Would You Recommend?YesHappy with my purchaseHave 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.May 25, 2020Durability5 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5May 19, 2020Purchased

4 weeks agoDurability4 / 5Reliability4 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5Would You Recommend?Yesworked great out of box on long cross-countryAfter 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!May 15, 2020Durability5 / 5Reliability5 / 5Performance5 / 5Ease Of Use5 / 5Value5 / 5Very easy to connect!

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.May 12, 2020Purchased

- Question and Answer
Browse 79 questions Browse 79 questions and 92 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.Are there any feature/function comparisons with the Stratus 2S and 3?ForeFlight Sentry ADS-B ReceiverBEST 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?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: 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?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?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.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?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"BEST ANSWER: "Smart Wi-Fi" feature will available in the future app update.DOES THIS PRODUCT COMES WITH A MOUNT ?BEST ANSWER: Yes, it has a suction cup mount.Does this only work with fore flight?BEST ANSWER: Yes, it only works with ForeFlight.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.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 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.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?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?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?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?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 10500BEST 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?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. ThanksBEST ANSWER: Sounds as if the unit is defective. Please return it to us.Can I Use this item in Europe : France and Switzerland ?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?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?BEST ANSWER: We expect to have this back in stock on June 6th, 2020So, do I understand correctly that the sentry will not work if you loose a wifi connection?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?BEST ANSWER: No, it is not.Is the gps in your phone the same strength as the gps in this device?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?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 CanadaBEST 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?BEST ANSWER: It is not. It is only compatible with Foreflight.
