Additionally, the device comes with doneness settings that let you adjust the end result to your preferences - be they rare or well done. Also, you can set your own temperatures.

The large LCD display with backlighting is designed to fit perfectly on the grill or smoker, so you can easily monitor temperatures without opening the lid and losing valuable heat.

The count-up timer is perfect for keeping tabs on how long your food has been in the oven or on the grill while you are waiting for it to reach the correct temperature.

The count-down timer is useful for side dishes and other items that need to be cooked for a set amount of time before being turned off.


TP20 has two meat probes, and each of them can withstand a maximum temperature of up to 716°F while still maintaining its function and accuracy and sending data to the wireless receiver.

You can place the probes of TP20 in two different types of meat or use one probe to track ambient grill temperature.

The TP20’s dual-probe system is designed to find your meat’s internal temperature precisely and quickly with a step-down tip design.

  • Simple setup and sync
  • A more accurate reading than the ET-733
  • Count-up timer function
  • Easy-to-use and durable thermometer
  • The alarm is not loud

The Maverick ET-733 thermometer is wireless and can be used to monitor the temperature of your food from 100 yards away.

This thermometer has an alert function that alerts you when your desired target temp has been reached, so you don't have to worry about constantly checking it and overcooking or undercooking your meal.

Wireless Range

he ET-733 is perfect for homes with a large yard, as it has an extended wireless range of 300 feet.

This allows you to freely move around your back garden without breaking the signal.

It also has an inbuilt alarm that creates audible alerts when you have moved outside the range for around 60 seconds.

Accuracy and Range

The thermometer's wide temperature range of 32°F to 572ºF (0°C to 300°C) makes it versatile for measurements both indoors or outdoors.

However, compared to the TP20, this instrument may not be as precise with tolerances up to 3-4ºF.

Using an accurate food thermometer takes the guesswork out of cooking.

This BBQ thermometer comes with a whopping 15 meat temperature presets.

In addition to the nine that you will find in the TP20, the ET-733 has some more eclectic choices like moose and elk.

Regardless of what you are cooking, the ET-733 has a preset to ensure you end up with safe and properly cooked meat.

Setup and Display

The temperature display of the ET-733 has a nicely backlit LCD screen and is quick to respond. Like the TP20, it is large enough for three rows of information that are easy to see and read.

The setup of this digital meat thermometer is relatively simple.

However, it is recommended that you turn the receiver on before the transmitter to avoid conflict. By using this turn-on order, you will be assured of a stable connection.

The timer on the ET-733 is of the count-down variety. It works great for timing how long something has been cooking, which is critical when cooking a full meal.

Unlike the TP20, the ET-733 does not have a count-up function. Instead, it relies on the temp alarms to keep the cook informed as to when the meat has reached its desired doneness.


The ET-733 has two probes that come with individual grill clamps to ensure they stay in place while cooking.

Each grate clip ensures that the individual single probe does not move while sending information to the main unit.

You can use one as a meat probe while using the other as an ambient temperature probe.

The dual probes can withstand temperatures up to 716°F, and they have wires that are 3 feet in length.

  • Each dual-probe has individual grill clamps
  • 15 programmed presets for meat and game
  • Excellent wireless range
  • Probes need to be replaced more frequently

ThermoPro TP20 Or Maverick ET-733 - Which One is Better?

Overall, the TP20 and ET-733 digital meat thermometers are both popular thermometers because they are of high quality and very easy to use.

Neither version is an instant-read thermometer, nor are they infrared thermometers. Instead, each is a wireless device that extends beyond the Bluetooth range.

Additionally, these BBQ thermometers have many similar features.

For example, they are both battery-powered by four AAA batteries, can use both Fahrenheit and Celsius units, and come with heat-resistant probe wires.

However, there are enough differences between these digital thermometers that I can unhesitatingly recommend the ThermoPro TP20 as my top choice.

If you are looking for a new thermometer, the TP20 has unparalleled accuracy and an easy-to-use display interface that offers exceptional functionality.

The flexibility of the count-up and count-down timers is a bonus for the cook looking to time multiple dishes.
