Try the
fireboard. It’s a tad expensive but here’s a link to a review I did for them. I have had one for a year and track all my smokes and can share them.
Fireboard Review
Dear
Fireboard,
I purchased my
fireboard etreme BBQ edition in Early April 2017. I was going to be using it on a
Chargriller 50/50 with the side fire box. Here is the first cook ever, all charcoal and wood fire. This was before any mods with Charcoal tray still in.
Channel 1 was right and Channel 2 was left side of grill. As you can see my temps were all over the place. But the fireboard probes stood up to the heat and to this day I stll am using the same probes I was using that day. Over the course of last summer and this summer I have done many upgrades/improvement to my smoker. One thing that has stayed the same and constant is the fireboard on the original probes.
Here is a more recent cook on propane now.
My temps have evened out more and the food keeps getting better. This cook was done this April 2018. If you look at the channel names you will see I monitor all 4 points in the smoker. I started this cook with the battery fully charged and when I finished the almost 17 hour cook it still had 25% battery remaining. The battery is a over a year old and has been used in freezing temps doing cooks all day. Never been a issue.
The fireboard has remanied tried and true. When it say's it's done, It's done. I have done close to 200 cooking sessions with the firebord since buying. I have used it on the Gas Grill, Gas Griddle, Deep Fryer, oven, and stove top. I leave my cooks going all day. When I walk away, I know exactly what is going on at all times. Since coverting to a gas smoker I have started to have even more free time while cooking. Just set the alerts and the app will do the rest. Couldn't be more please with the fireboard and probes. The app or the website both work flawlessly for my Iphone 5 and 8 that I have now. Saves all your cooks so you can look back and see what you did. It makes you a better cook.
On another note there customer service is awesome and only something bigger companies could dream of. I had just a question about the fireboard when I first got it. I emailed them while I was on nightshift 2 am in the morning. By 9 am that day I had a reply with the answer from Ted one of the owners I believe. I have talked to them several times since and they're always happy to help. All in all the best purchase I have made for my grill/hobby. Well worth the money.
