Standout Benefits of the Lavatools Javelin Pro Duo
The Javelin Pro Duo is built to make checking temperatures simple and safe. The design gives users a highly accurate temperature reading with convenience and ease of use.
Lavatools Javelin Pro gives you the accuracy you need when you are cooking and grilling. It consistently provides a temperature readout with an accuracy of less than a single degree (Fahrenheit). Because of this, it makes for the most accurate cooking times, so you avoid overcooking your food.
Its ambidextrous design makes it one of the only thermometers that work as well for lefties as it does for right-handed people. You don’t have to twist your head to read the display because the readout automatically rotates for you.
That alongside the probe’s foldable angle makes it perfect for use with either your left or right hand. That also fixes issues when you are trying to check the temperature from strange angles, say in a turkey.
You are sure to stay safe with the long-handled design of the Javelin Pro Duo. The entire length of the handle plus the probe make sure your hands are far away from a grill (or another heat source) when you are checking temperatures. Avoiding burns is a great benefit, whether or not it is a simple solution.
A Guide to Using the Javelin Pro Duo Your First Time
The Lavatools Javelin Pro Duo is simple to use, straight out of the box. The Lavatools Javelin Pro will automatically turn on and off. If it is left idle, it will turn itself off, and as soon as you pick it up, it turns back on.
Since it comes pre-calibrated, you don’t need to worry about the accuracy of your new thermometer. Choose whether you want Fahrenheit or Celsius displayed before using. Once you have this simple step done, you are ready to go.
Just insert the probe into the food you want to check, and wait for the thermometer to beep. The beep is to let you know it has locked in the temperature and will continue to display it on the screen for several seconds.
Make sure to wipe off the thermometer when you are done using it. While it is IP65 splash resistant, it will ensure your product keeps working (and isn’t a sticky mess).
Lavatools Javelin Pro Duo Description & Features
The Sturdy Body | The Ambidextrous Display | The Intelligent Stabilization Alert
The Javelin Pro Duo is a great piece of equipment and comes packed with features and incentives galore.
The overall build is both a simple aspect of the Javelin Pro Duo and one of its best perks.
The Sturdy Body
The sturdy body of this thermometer shows that it will not only last a drop to the floor (most likely) but it won’t break down because of a splash of soup or brewing beer.
The body comes with an antimicrobial coating as well, which is nice to know, even if you are going to clean it after every use. Nobody likes food contamination, and Lavatools listens to those worries.
The Ambidextrous Display
The ambidextrous display is another awesome feature of the Lavatools Javelin Pro Duo, and might just be where it gets the name from (though that is not certain).
The display is great all around. It is a 2-inch display, making it easy to read even in the harshest conditions, and features a backlit display that turns on automatically when needed. The auto backlighting is very helpful for grilling at night.
The Javelin Pro Duo’s display automatically rotates, so if you change the angle of the thermometer, the display rotates to always show the right side up. This is a fantastic addition for any left-handed grillers out there.
It can be a pain trying to check temperatures when the display is either upside-down or facing away from you. The display allows anyone to easily check the most awkward angles of their food. Roasting a turkey? This will make it simple to get in any position you need to check its temperature.
The Intelligent Stabilization Alert
The intelligent stabilization alert and temperature display hold is a combination that makes the Lavatools Javelin Pro one of the best digital thermometers out there.
Within three seconds or less of inserting the probe into your food, the thermometer will beep at you. That beep is to let you know that the temperature has been found.
The locked-in temperature will continue to display on the screen for several seconds. This makes it simple to check temperatures in the oven or grill when you want to get in and out quickly.
You don’t have to stare into the oven with the thermometer still in your food, instead, you just insert the thermometer and wait to hear the beep. Once the alert goes off you can pull your Lavatools Javelin Pro Duo back and check the temperature easily.
Who Is the Javelin Pro Duo For?
The Javelin Pro Duo is a great product for anyone needing a new thermometer. If you are a griller, baker, cook, or even a beer brewer, this thermometer is the top-of-the-line for what you are looking for. It is in the mid-range price of an average instant-read thermometer, but the extra money shows in the Javelin’s design and features.
If you are looking for a cheap thermometer, you might not want the Lavatools Javelin Pro Duo, but you will wish you had spent the little extra cash to ensure you had the extra features.
Reasons to Think Twice
If you are a griller that enjoys moving around as you grill your food, an instant-read thermometer might not be what you’re looking for. A wireless remote thermometer might be more up your alley.
This is especially true if you smoke food often, or slow grill your food at specific temperatures.
The Lavatools Javelin Pro is great for single food items, and for checking quickly at a time, but it won’t give you readings on the temperature of your grill, and won’t display several temperatures at once.
Lavatools Javelin Pro PROs & CONs
The features and overall build of this Lavatools Javelin thermometer are both big pros for the product. The automatically rotating screen, intelligent stabilization alert, and automatic power switch are all fantastic perks that are rare to find in other instant read thermometers.
The price may be the biggest con with the Javelin Pro Duo. It certainly costs more than the low-range instant-read thermometer. For some people, $50 can seem a bit expensive for a single piece of cooking equipment, especially one that isn’t technically cooking anything.

Final Thoughts on Our Lavatools Javelin Pro Duo Review
This is my last chance to say how wonderful the Lavatools Javelin Pro Duo thermometer works. My only concern is that it is on the mid-range of the price side and may not fit into everyone’s budget. If that is your concern, a great low-cost alternative is the original Lavatools Javelin PT12, which is around half the price.
Even with that, I’ve been waiting to test out this thermometer for a while now and for the most part, I love it.
The Javelin Pro Duo is a pretty awesome product, and I believe, it’s at a reasonable price for the benefits and features you get. Don’t think twice about buying this one if you are in the market for a true instant read thermometer that will stand the test of time. You won’t find much better.

Very interesting piece of equipment. Thanks for sharing your views on it Patrick. You seem to be a BBQ chef and you sure know your stuff. You do have a serious collection of products to chose from.
One question though: Are you in favor of gas or charcoal for BBQing?
An instant read thermometer is one of the most used pieces of equipment every time I cook. I can’t stress enough how helpful a fast and accurate thermometer is for upping your grilling game. I am a fan of charcoal and cook on a charcoal grill eight out of ten times, but I also have a gas and wood pellet grill I enjoy using as well.
Thanks for stopping by John and Happy Grilling!
Thanks for your helpful review. The information provided convinced me to purchase the Javelin Pro Duo after seriously considering your top rated Thermapen MK4. Amazon customer reviews also supported your assessment, but your review made up my mind. The MK4 looks like a good option but I probably wouldn’t realize any advantages offered and I’m happy to save $50. On the other hand, I’m pretty sure I’d miss the Pro Duo’s features if I’d purchased the Javelin Pro for $25 less. The Pro Duo filled that sweet spot in-between those two alternatives. I’m looking forward to its arrival.
BTW — I a recently purchased a Big Green Egg after many years of using gas grills. Do you have any tips for a BGE newbie? Thanks again.
Hi Steve. Sorry for the late response but I have been laid out with the flu. I excited to be back up and grilling again. I get really pumped when I am able to help someone so I thank you for your comment. Even though I have been using a Thermapen for a while, (and I love it by the way) I get a chance to test many different cool gadgets. I think you will be happy with your new Javelin Pro Duo as it performed very well for me while I tested it. I hope you stop back by to let us know how it is working out for you.
I want to be the first to welcome to the BGE Brotherhood! I love mine and I know you will love yours too. It takes a little getting used too, especially coming from a gas grill, but once you get it down you will be wondering how you cooked without it. A great resource for all things BGE can be found here. Also, Youtube is your friend. You can find awesome videos with recipes and cooking methods for the Egg that is really helpful. If you have any specific questions, shoot me an email and I will be glad to help out.
Thanks again for your support.
I AM TRYING TO BUY 3 JAVATOOL JAVELIN PRO MEAT THERM. AND I CAN’T GET ANYWHERE WITH AMAZON.
I AM SICK OF THIS
Hi Richard. Not sure what is going on but if you explain, maybe I can help out.
How do change between F’/C’? I’ve followed the instructions and cannot find ANY toggle switches inside the battery bay.
Certainly expected ease of operation for the investment.
There are toggle switches inside the battery compartment to switch between F’/C’ as well 3 additional options. The switches are labeled 1 through 4 if I remember correctly. A small flat head screw driver will make it easier to manipulate the switches.
Here is a copy of the user’s manual with some pictures that may be helpful.
