The smartLink 851 is a Flight Data Recorder, CO Detector, USB Power Supply (dual 2.7 amp)  that works with the Guardian Avionics smartPlane app system. This unit
is remote mounted behind the panel or on a smartPlane iPad mounts to save space in smaller panels. The smartLink 851 communicates with the smartMFD iOS app via a hard wire USB connection.

Start with the CO Poisoning Prevention that Guardian Avionics is Known For.

The smartLink 851 is built around the reliable and accurate Carbon Monoxide detection technology that Guardian Avionics and CO Guardian has been known since 2003. The sensitive onboard CO sensor alarms an initial warning when CO levels measure greater than 50 parts-per-million (PPM)
up to 99 PPM. When the CO level is triggered at 50 to 99 PPM will signal an alarm around 3-1/2 minutes. A warning will trigger when levels climb above 100 PPM immediately when detected.

Your GPS, Engine Monitor, and Attitude Connect & Display on Your iPad & iPhone.

The smartLink 851 can be connected to your onboard GPS (Garmin GNS430, 480, 530, GTN625, 635, 650, 725, 750, GTN750Xi, 650Xi, GNX375, GNC355, and Avidyne IFD440 and 540). AHRS data from Garmin G5 or 3X and G3X Touch
can be displayed on IOS app. Engine Monitor (Garmin G3X and G3X Touch, JPI EDM730, 830, 900 primary and Experimental, 930, Guardian Avionics EM100 see link below for a full list of products) via RS-232, allowing accurate navigation and engine performance data to be aggregated,
transmitted, displayed, and recorded on your iPad and/or iPhone through the Guardian Avionics smartMFD app. The data stored on the iPad or iPhone is transmitted to the Cloud via cellular or Wi-Fi located at www.guardianavionicsdata.com.
As a result, your iPad and iPhone become mini-multifunction displays -- fully equipped with accurate VFR and IFR maps and charts, rich graphical engine performance information, and even a mini-PFD/MFD for
quick reference. All Carbon Monoxide alerts and levels are also available on the smartMFD app too!

Your 851 connected to your ADS-B.

With our new smartLink system unit 851, it’s now easy for you to connect your Flight Data Recorder to your ADS-B! Meets the FAA requirements of January 2020.

ADS-B receivers can make your flight safer and more efficient by providing you real-time weather, traffic, TFRs, and other flight data. 

Our Flight Data Recorder can easily be connected to a large panel of ADS-B units in the market such as FlightBox ADS-B, Avidyne IFD series (440,540) and much more.

Your 851 connected to your Radio (NAV/COM) 

Our smartLink 851 Flight Data recorder cannot only be connected to your GPS, Engine Monitor and ADS-B, but also to your own Radio through a solid RS-232 connection. 

Radio includes Navigation and communication tools such as VOR/LOC/GS and VHF comm transceiver allowing you to have a full and complete package. 

Our 851 Flight Data recorder is compatible with a large panel of Radios available in the market such as the Garmin SL-30, Trig TY91, Trig TY92, GTR225, and GNC255. 

All Your Flight Data is Sent and Stored in the smartData Web site at www.guardianavionicsdata.com for You.

Through the smartMFD app, all of your flight data is stored and uploaded to your account on the Guardian Avionics smartData web site via 3G/4G/LTE or WiFi at the end of every flight, with the ability to download and view flight tracks on programs like Google Earth, view engine data
through rich charts and graphs, and even export your data for use through other programs or to send to others. If your iPad mini is connected to your audio panel through a 3.5 mm audio jack, the app will even record the audio from your intercom and upload it to your account for each flight too!

How can you use the data?
See how accurate your recent practice approaches were on a recent flight. Send trend data to your A&P or engine manufacturer to troubleshoot an issue. Evaluate all aspects of a recent training flight, including radio procedures.

Budget and Panel Space Friendly.

Equipping the smartLink 851 is like bundling multiple pieces of equipment into one compact remote mounted or smartPanel mounted unit. In the past you’d need to buy and install a CO detector, GPS signal booster, USB Power
Supply and backup AHRS for your iPad/iPhone as separate items – and flight data recording on an app for both navigation and engine data was not even available! Now you can get all of that in one small, easy to install package for one reasonable price!

FAA NORSEE Approved for Part 23 Aircraft Installation.

All smartPlane products from Guardian Avionics are approved for installation in certified aircraft under 14 CFR Part 23, 27 and 29 as "Non-Required Safety Enhancing Equipment" (NORSEE) as outlined in FAA
memorandum number PS-AIR-21.8-1602. Installation requires only a minor alteration logbook entry by the installing A&P mechanic or
inspector.

Great toy for our best boys!
Color: Consuela the Cactus - Large, Size: Large Dog
You can never go wrong with BarkBox toys and this was no exception. Our dogs like toys that have squeakers and that they can tear into. This style of toy fits the bill. The design is cute as well. I’ve had this in the house for months and, while it’s definitely seen better days, it’s still intact and they haven’t gotten to the inner layer. (Not for want of trying.) The perfect type of toy for our fur babies.

Survives 7 months so far.
Color: Christmas Consuela, Size: Large Dog
It is still intact after nearly 7 months of constant play. My blue heeler normally destroys toys in just a few weeks. Consuela has exceeded expectations of survival with an extremely chewy, destruction prone dog.

Short-lived but much enjoyed as a chew toy
Color: Consuela the Cactus - Large, Size: Large Dog
I bought two of these for my "granddogs" in the size for Large dogs. The German Shepherd-mix stole the one intended for the border collie-mix and had both toys halfway destroyed within a day--I'm pretty sure they didn't survive much longer after that. Much enjoyed! Maybe I should've bought the Extra Large size, because the Large barely fit in her mouth and she wanted to play tug-of-war, so there wasn't much for me to grab onto. Then the border collie wanted in on the action (she's older, so she needed help tugging!) but there wasn't enough material for her to grab onto without accidentally sinking her teeth into me instead.

Love all the Barkbox toys
Color: Christmas Consuela, Size: Large Dog
This is our third "Consuela"! Our dogs LOVE these toys, and they are the most durable we can find for our heavy chewers. They really like the ball inside as well. Highly, highly recommend these toys. I won't be buying other toys anymore, just barkbox.
