MEATER Plus Wireless
Best for: Smoker and grill owners who want phone-based monitoring.
#3 in our rankings · Best mid-range
Lavatools Javelin Pro Duo
Best for: Home cooks who want fast reads and a display they can read at arm's length.
Our recommendation
Our take: This is a use-case decision, not a quality contest. Choose the MEATER Plus for smoking and long roasts where continuous monitoring replaces babysitting. Choose the Javelin Pro Duo for grilling and everyday roasting where fast spot-checks are the job. Many serious cooks eventually own both because the jobs do not overlap.
Monitoring versus spot-checking
The MEATER stays in the meat for hours, reporting internal and ambient temps to your phone. The Javelin gives you a reading in 3 seconds and comes back out. Smoking needs the former; grilling needs the latter.
Complexity and failure modes
The Javelin has one job and no dependencies: pick it up, read, done. The MEATER depends on Bluetooth range, battery charge, and the app. When everything works, the MEATER is magical; when the battery dies mid-brisket, you will wish for the Javelin.
Speed and precision
For the final doneness check, the Javelin's 3-second instant read beats waiting on a wireless probe's update interval. Wireless probes sample periodically; instant-reads answer now. That is why pitmasters use both.
Choose MEATER Plus Wireless if…
- You smoke meat for hours at a time.
- You want phone alerts instead of hovering.
- You cook roasts where oven monitoring helps.
Choose Lavatools Javelin Pro Duo if…
- You mostly grill steaks, burgers, and chicken.
- You want the simplest reliable tool.
- You prefer no apps or charging.

Strengths and limitations
MEATER Plus Wireless
Strengths
- Completely wireless probe with 165 ft Bluetooth range; no cables to snag or melt.
- Dual sensors track internal meat temp (to 212°F) and ambient cooker temp (to 527°F) simultaneously.
- App estimates cook time and rest time from the temperature curve.
Limitations
- Bluetooth range drops with walls between the grill and your phone.
- The probe is thicker than instant-read probes, leaving a bigger hole in delicate fish.
- Requires charging between cooks; a dead probe mid-smoke is a real failure mode.
Lavatools Javelin Pro Duo
Strengths
- Reads stabilize in about 3 seconds, close enough to premium for most cooking.
- Large auto-rotating backlit display is readable in bright sun and dark kitchens.
- IP65 waterproof and magnetic back sticks to the grill or fridge.
Limitations
- Not as fast as the 1-second Thermapen ONE for thin cuts like fish.
- Plus-or-minus 0.9°F accuracy, a step below the Thermapen's 0.5°F.
- No app or wireless features for long cooks.

Questions, answered
Can one replace the other?
Not fully. A wireless probe cannot match an instant-read's speed for the final check, and an instant-read cannot monitor a 12-hour smoke. If you do both kinds of cooking, budget for both tools over time.
Which should I buy first?
The Javelin. Every cook needs an instant-read; only smokers need wireless monitoring. Buy the MEATER when long cooks become a regular habit, not before.
