Thermoworks Smoke with gateway here. It’s pricey, but it’s a insurance policy especially after numerous cooks. You don’t want to trash. $30 turkey let alone a $75 brisket. My thermapro (rebranded Maverick, Familie, etc. ) had as much as a 30 degree temperature swing inaccuracy. Invest in either a Thermoworks Instant read to validate temps or, like me, start a Thermoworks obsession and buy a Smoke, Gateway, Dot and Thermapen! You won’t be disappointed.
