The original MEATER and MEATER Plus use the same probes, and the difference in range comes from the Bluetooth booster in the MEATER Plus charger.
The probes that come with MEATER Block have the same range as the original MEATER and MEATER Plus probes, so just like with MEATER Plus, the charger should stay as close as possible to your cooker to stay connected and boost the signal over WiFi.
