Ultimate Holiday Bundle

Cook 4x the meat

The ultimate gift package for BBQ Bosses and Pitmasters. Cook a whole cow at once, nothing can stop you. 

Set includes four 2nd Gen Predictive Thermometers with WiFi Boosters and a WiFi Display to manage them all. The kit comes with a handsome black carry case, fridge magnet, pot clip, and stainless steel ID tags. 

Rugged 2nd Gen Thermometers

Nitrogen-flushed, and hermetically sealed with a brazed ceramic bond, the 2nd generation CPT has the highest ingress protection possible (IP69K). It’s suitable for vacuum-sealing (hello sous vide!) and can tolerate extreme cooking temps of up to 900ºF. 

Extended standby life for every thermometer

Each Booster keeps a CPT ready to go with up to 9 months standby time. Recharge your thermometer up to 16 times from a Booster’s onboard battery.

So much WiFi

Monitor your food from anywhere with MeatNet™ Cloud and the Combustion App. Use any of the WiFi Boosters or the WiFi Display as a base station, and stream all that delicious cook data to your phone or tablet. 

Cook on or off-grid

All the tools work with or without a WiFi connection - so if you’re on the range or on the run from the law, you can still enjoy a quick steak or hide away from society without sacrificing the quality of your brisket. Watch the temps on the Display or on your phone over local MeatNet. With this set, the whole world is your cookspace. 

All the features you love from Combustion, plus numerical superiority

Every Predictive Thermometer uses 8 sensors to give Total Temperature Awareness™ with live temps from edge-to-edge plus ambient temp. The TrueCore™ technology always locates and measures the lowest internal temp – even if you miss the center. And there’s SafeCook™ and the peerless Predictive Engine™ and more.

Cook all the things!

  • Integrated food safety

    The Ultimate Holiday Bundle now includes SafeCook

    Combustion’s SafeCook™ keeps a running total of the bacterial body count at every step in the cooking process.

    It tells you exactly when your food has met US government food safety guidance.

    These are the same USDA-FSIS/FDA standards used by commercial food preparers. But with SafeCook, the Predictive Thermometer does all the math.

Shipping

All orders are shipped in the order received. 

It takes 1-3 business days to process orders and get them on their way. At that point, you'll get a shipping confirmation email. Shipped!

In periods of very high demand, products may be temporarily back ordered while we are waiting for inventory to arrive.

In that case, the estimated ship date will be listed in checkout (for example “ESD: Aug 21, 2023”) - that’s when your order is expected to arrive at our US warehouse for processing.

When it arrives depends on the shipping method, location and (for international orders) customs inspections and other random events. 

Domestic shipping

Prices and shipping options are listed in checkout. (Please don't use the fast delivery options for products that are out of stock or for preorders. It won't get there faster.)

Worldwide shipping

No surprises! We ship to most countries Delivered Duties Paid (DDP). That means everything-taxes, duties, import fees, and shipping fees-are calculated and pre-paid at check-out.

What changed with the 2nd generation Combustion Predictive Thermometer?

A more durable, fully hermetic seal and higher maximum temperature range.

Using high-temperature ceramic-to-metal brazing, we create a true hermetic seal between the ceramic handle and steel tube. Unlike conventional seals or adhesives that can degrade over time, this brazing process creates a permanent metallurgical bond at the molecular level. 

The result is a completely hermetic seal that's tested to IP69k standards – the highest ingress protection rating available.

Key improvements:

  • True hermetic seal - safe for vacuum sealing, sous-vide, and deep-frying
  • Extended temperature range - high-temp region now reaches 900ºF (482ºC), up from 600ºF
  • Enhanced sensor performance - relocated ambient sensor provides faster, more accurate readings
  • More durable construction while maintaining all original smart features.

We also introduced built-in WiFi to the second generation accessories (WiFi Display, WiFi Booster, Giant Grill Gauge).

What about WiFi?

Any Combustion Predictive Thermometer (CPT) can be used with any of our new WiFi accessories (WiFi Display, WiFi Booster, Giant Grill Gauge) to connect to WiFi and send live cook data to anywhere in the world with internet access. Be sure to get the newest firmware to use this feature!

WiFi's higher transmission power (more than 10x that of Bluetooth) allows for excellent coverage throughout your home and, through your network, anywhere with internet access. This is especially useful when cooking from your basement or other locations where lower-power signals might struggle.

Why isn't WiFi in the thermometer itself?

It comes down to optimizing battery life while maintaining performance. WiFi draws significantly more power than Bluetooth, and the thermometer's battery must be small enough to fit near the probe tip. By using Bluetooth's energy-efficient design, we can achieve industry-leading battery life (over 92 hours) while still maintaining rapid data updates - every 5 seconds during normal cooking, and up to 5 times per second when it matters most.

Using a separate tool for WiFi connectivity means the thermometer can dedicate its power to what matters: collecting data, calculating predictions, running algorithms, SafeCook™, and all the other features that make the CPT special. 

This design choice helps us maintain the longest functional battery life of any wireless thermometer, even while processing more data than our competitors.

Anything else I should know?

Oh my yes. 

The Combustion Predictive Thermometer was designed to be a tool for professional chefs, but to also be easy to use by cooks at any skill level. 

Read as much as you can. The deeper you dive, the more I think you’ll appreciate the genius (and occasional madness) of what we’re doing. 

We’ve been very fortunate to have found a community of like-minded cooks who appreciate the extra insight and deep data our tools can provide. And we’re regularly surprised by the new and unusual uses that people are finding for the Combustion Predictive Thermometer (Beehives? Raw milk?). 

If you like cooking and science and the science of cooking, welcome. You’re in the right place. 

If you’re not sure about the CPT yet, do your research. Watch Chris’ videos - they’re full of surprising cooking science and practical techniques. Read the posts on our subreddit - there’s a lot of really specific discussion about how to use the thermometer and the people there are always pushing the limits. 

There’s also a ton of info on our help center, searchable by topic and keyword. 

Or you could always just jump in - we stand behind all our products with a 30-day money back guarantee. 

If the Combustion Predictive Thermometer doesn’t improve your cooking outcomes, or your process, or if it’s just not your bag for whatever reason, return it for a full refund of the purchase price.

I have a different question that is not answered here?

The first thing to try is our help center/FAQ. You can search by topic and learn more than you ever needed to know about the Predictive Thermometer and other Combustion tools. 

If you have no luck there, our subreddit is a good bet.

If that’s not your jam, please write us (there's a link in the footer). We’re always happy to help.

Can we split up this set and go fourth-sies?

No. I mean, that would totally work and we can’t stop you.

Each Predictive Thermometer could work on its own using its Booster for WiFi (or direct to a phone/tablet with Bluetooth). 

You’d have to divvy up the WiFi Display and the various accessories though. 

We would prefer it if you bought one Ultimate Holiday Bundle for each and every person on your shopping list and a spare for your postal carrier. They work so hard all year.
