Digital Thermometer advise

FB is a temp controller, has a fan to increase air flow.
Above is a thermometer.

Two different applications, not a fair comparison.

I'm pretty sure that is the electronics from a Maverick ET-733 in a different housing.  The probes look different as well. I have been through a couple of previous versions of the Maverick ET and they worked fine. My only complain was the probes failed.  Only other complaint was it was a pain to set the alarms but it looks like they have improved that.  The old versions only had an up arrow and if you passed your setpoint you had to roll back around like a crappy old alarm clock.  This unit might be worth a shot. 

As others stated this is just to monitor the temp. The flameboss actually controls the temp so it is a different animal. 

I think the Cadillac of remote temp monitoring would be the new smoke:

Thermoworks makes professional grade equipment. 

Welcome and Congratulations on the new egg.

Here is my humble advise...

I recommend that if you don't already have a instant read thermometer, that should be #1 on your list (the ThermoWorks Thermapen is the gold standard). 

After that, if your looking for a remote thermometer to monitor your pit and meat temps, you consider the ThermoWorks Smoke. It's built well and very easy to use. 

I'd hold off on a temp controller. I'd spend some time and learn to control temp manually. It's a bit of a learning curve, but you'll find that once you stabilize your temp, the egg holds it very steady for many hours. After that you made decide that you really want a temp controller... or not.  

Have fun with your new egg, try new recipes and techniques if you have any questions please ask, the folks on this forum are always willing to help.

I would also recommend the Thermoworks Smoke as well. Everything Thermoworks makes is very good quality.

Look at www.fireboard.io and thermapen

Hey @JBPRIME - a little advice:

The remote thermometer is a great tool to have, but they are a bit finicky in my experience.  At least, the probes are.  Here's what I've learned by ruining a few probes:

Water - do NOT get any water on the probe where the cable/wire enters it.  So when you wash them you can't just toss them in a sink full of soapy water.

High temps - High cooking temps will ruin them too.  With mine once the Egg hits about ~550*F I get an error reading of "HHH" and if I don't get it out of the Egg fast enough it'll stop working all together.   

I've got an extra probe laying around just in case I kill another one.

I mention the heat because you said you want to start with steaks/burgers/etc.  I like cooking my steaks at temps that will ruin my probes.

Welcome and good luck!!

What makes the smoke better than maverick or igrill?

I own both. I think the Maverick is OK for occasional backyard use. However, I cook in competition and the Mavericks have failed me more than once. Quality is far better with the Smoke. There is a good comparison in Amazing Ribs.

@chasgh  - Glad you asked.  For me, from a backyard cook perspective, the difference is in some few seconds of read speed.  And I cannot justify the $$ against the pop lag time.  I have gifted several pops to relatives and friends-all appreciate the response.  I would replace my thermapen with a pops (which did not exist when I bought the ...pen) should it ever go to the thermo graveyard.  FWIW-

I will pile on the Thermworks bandwagon. I have Thermopop and Thermopen. I will likely get the Smoke also when the gateway (wi-fi push to an App on your phone) becomes available later this year. 

FYI, I emailed Thermoworks before Christmas to ask them if I purchased the Smoke now would the Gateway work with it when it was released and they said yes.  It seems they are two separate devices, so you can get the Smoke now and the gateway later.  Not sure if this changes anything for you but just wanted to let you know.

They are not on TSA's list of prohibited items.  TSA says that knitting needles are allowed, so I am guessing that the Thermapen should be ok.  Don't have any idea about international flights.
