The Core 2, the second iteration of the body temperature sensor from Core, is anticipated to be released in late March 2025, presenting a more compact, lighter, and user-friendly design to the market. While it doesn’t overhaul its predecessor, it introduces smart enhancements to an already valuable instrument for those regulating heat during training and competition.
More Compact and Lightweight
If you have utilized the original Core sensor, the modifications in the Core 2 will be apparent immediately. It is nearly half the dimensions and considerably lighter, meaning it’s less obtrusive during extended runs, cycling, or races. Specifically, it is 48% smaller and 30% lighter than its predecessor. The attachment mechanism has also been redesigned to stay secure during activity while simplifying the charging process.
A great feature is the implementation of an LED status indicator. It allows you to quickly verify the battery or device condition without needing to interact with your smartphone or training watch. This is another functional enhancement that you might overlook initially but will surely value during regular usage.
Maintaining a Focus on Real-Time Heat Training
Similar to its predecessor, the Core 2 remains concentrated on monitoring body temperature in real time. This is beneficial if you regularly train in warm environments. The small device is compatible with well-known platforms like Garmin and Wahoo through Bluetooth and ANT+, ensuring that your data is readily available and actionable during training sessions. This enables you to check your statistics without managing additional apps or gadgets.
Even though the Core 2’s capabilities are quite alike to the original at launch, the hardware is designed to adapt to future software updates. These anticipated enhancements, expected to be released later in 2025, may introduce new features that keep the sensor pertinent for years ahead.
Facilitating Transition for Current Users
Priced at CHF 269.95—the same cost as the original—Core 2 will be accessible globally starting in March 2025. For current Core 1 users, the company has put forth a trade-up initiative. By returning their old sensors, they can receive credit toward the Core 2. Furthermore, the company offers a discount on Core 1 units while supplies last, providing new users a chance to experience the platform before committing to the next-generation model.
