  • Maverick ET-732 Wireless Thermometer Review

    Hey, All -

    I just posted a review of the Maverick ET-732 on Amazon, where I purchased it.  Thought I'd post it here as well, as there seems to be a fair bit of discussion about it and like products on this site...  

    Purchased this item with high hopes, based on mostly good reviews here.

    I grill with a Big Green Egg. My (wonderful!) wife got me the BBQ Guru temp control unit for Christmas. Love the Guru, but it's not wireless, so I've been using the Maverick ET-732 in conjunction. The Guru is meant to maintain the correct temp, I used the Maverick to alert me in case something went wrong.

    Got the grill set at 250 degrees. Had the temp probes for the Guru and the Maverick in the same exact spot. Both had been calibrated properly. For the first four hours of an 18-hour smoke, the temps registered within 1 to 2 degrees of each other. Everything working perfectly! Woo hoo!

    About 4 hours in, the Maverick alerted me to a temperature spike - it shot from 250 to 302 in a matter of about 2 minutes. I ran outside to see what was happening. The BBQ Guru temp probe was still registering 250. The dome thermometer on the Egg was about 240. I peeked inside to see if the Maverick probe had come loose and moved closer to the fire. Not the case - everything still in exactly the same spot. 

    Within about three hours, the two probes were back in sync - momentarily. Now the Maverick was showing a swing to the low side. The alarm went off when the Maverick hit 210. Dubious, I went outside to check. Guru said 245. Egg dome registered 240. Maverick at 206.

    This continued throughout the cook. For 18 hours, I had a steady temp, according to the BBQ Guru (which, by the way, is an AMAZING piece of equipment!!) and the dome thermometer on the Egg, with both registering plus or minus 5 degrees of desired temp. The Maverick was the only thermometer that didn't stay in the same range the entire time, swinging wildly from temps as low as 194 to as high as 306.

    Long and short, I love the wireless capabilities of the Maverick - but it doesn't do me an ounce of good if it's not accurate. I'm willing to accept that any given thermometer is going to have a margin of error. However, the Maverick's margin of error appears to be plus or minus about 50 degrees, which is simply unacceptable.

    Do yourself a favor and forego this inaccurate piece of junk.

    All's well that ends well, tho - 17 pounds of pork butt now resting at the cooler, both pieces having hit 197 internal after 18 hours.  Seems that the Guru got the job done on my first overnight cook!
