Lavatools Javelin PRO Duo Thermometer Review

Lavatools Javelin Pro Duo Thermometer

Out of all the thermometers we've tested, the only one that meets our criteria of ease of use, accuracy, durability, AND at a reasonable price is the Lavatools Javelin Pro Duo Digital Meat Thermometer. 

At around half the price of its closest competitor in terms of performance and features, the Javelin Pro Duo is a tremendous value.

Value For Money



What We Like

  • Response time of 3 seconds.
  • Has most of the features as the more expensive, best-in-class Thermapen MK4.
  • Ambidextrous intelligent display automatically rotates depending on where it's held, great for lefties!
  • A large 2" backlit anti-fog display, great for cooking around steam.

What We Don't Like

  • Splash resistant but not waterproof so you can't go swimming with it (joke people).
  • You cannot leave it in the oven.
  • Not remote enabled.

The Lavatools Javelin PRO Duo is a fantastic upgrade from its predecessor, the original Lavatools Javelin. The Javelin PRO Duo is extremely accurate to within 0.9 +- F.  It has a large 2" backlit display that is motion-sensored, meaning that you can illuminate the display by simply moving the thermometer. This makes the Javelin PRO easy to operate even with bulky oven gloves on! 

The plastic shell is impregnated with a silver-based antimicrobial additive, inhibiting pathogen growth, killing bacteria at a rate of 99% or greater.

The thermometer will automatically shut itself off if left idle for more than ten minutes. This saves battery life and you simply have to move the thermometer to wake it up again.

Perhaps the coolest feature is the anti-fog, ambidextrous display. The Javelin PRO has built-in motion sensors that detect when the device is upside down. It will rotate to meet the user's eyes accordingly. This is great for awkward angles as well as left-handed people!

Lavatools Javelin Pro Duo Thermometer Review


The Lavatools Javelin PRO Duo is the most recent addition to the Lavatools family and is a terrific update to their classic original Javelin thermometer.

This mid-range priced digital thermometer has most of the same features of the expensive, best-in-class Thermapen MK4. Let's go through all of the cool features that Javelin PRO Duo has to offer.

Overview of Features

The Lavatools Pro Duo has a lot of great features that are incredibly helpful in the kitchen or bbqing outside on the grill.

  • Incredibly fast 3 second temperature reading response time.
  • A motion-sensored backlit display, the display lights up when you simply move it, great for bbqing outside in the twilight of evening.
  • Splash resistant shell.
  • A rotating display, the display will rotate around for left-handed users.
  • Stabilization alert.
  • Motion-sensored sleep/awake feature, if left idle for more than 10 minutes it will turn off on its own. To turn on again simply move it.
  • Antimicrobial coating. The shell is coated with a silver-based anti-microbial coating, which inhibits pathogen growth with efficacy of 99% or higher.
  • Ultra-sensitive thermistor sensor located on tip of the probe.
  • A maximum/minimum temperature feature that shows you the max/min temperatures for your current cooking session.
  • Battery life of 4000+ hours.
  • A magnetic attachment on back for easy storage.

Product testing and final verdict

We tested the Lavatools Javelin Pro Duo ourselves to see how well it performed.

To check the Javelin's accuracy, we cross-checked the Javelin's temperature readings with two other thermometers.  We chose the Original Super Fast Thermapen and the 6 probe Tenergy Solis Digital Meat Thermometer (the Tenergy Solis has over 300 -5 star reviews on Amazon.)

We cooked some chicken thighs in the oven.  After 20 minutes we checked the temperature, the Javelin PRO Duo gave a temperature reading of 149 degrees Fahrenheit in about 3 seconds, matching the reading of the Tenergy thermometer and within 2 degrees of the Thermapen.

One of the cool features of the Javelin PRO Duo is the motion-sensored, anti-fog backlit display, which can be helpful in dimly lit ovens or steamy environments.

The speed and accuracy of the Javelin PRO Duo checks out and is comparable to the other high quality digital thermometers on the market. With its multitude of features including its long  lasting battery life, the Javelin PRO Duo is a fantastic thermometer that performs on par with thermometers that are twice its price.

We're not the only fans of the Javelin PRO Duo, there are over 1000 reviews of this awesome thermometer on Amazon with a 4.5 star out of 5 rating. Check out what other people are saying by clicking the link below. Thanks for reading!
