I leave all chamber probes outside in the smoker year round suspended from the top rack so I can just plug in the displays (3) and (4 probes) and not thread everything every smoke. They stay under the cover in between smokes and are rarely cleaned while the transmitters come inside between smokes. I cook on the middle two racks with a drip pan on the bottom rack. The top rack is my hottest and I smoke dishes and pizza up top. The BT Soraken I got three years ago appears to have the same app as inkbird, tenergy, synergy, chugod, morpilot, silipower, ching chang, fling flang, ding dong etc. and many more now since I got it. I don't use all six but maybe for a whole packer brisket and another meat or two. It's been awesome and all four probes are meat and I just got the two colors I didn't have ($12) to occupy all six ports if needed but I don't foresee that . The meat probe I use as a dedicated chamber probe is accurate and faster than my other blunt ended chamber probes. I look forward to continued reviews on the rechargeable permanent batteries in the Inkbird devices which is the deal breaker for me. I know that heat will kill the longevity of any battery faster than anything so I don't quick charge my cell phone, especially wireless quick charge because of the heat that gets over 40*C or 104*F. I know how frustrating it is when you need a tool and it's battery is not charged like a drill whether nicad, nickle metal hydride or lithium. Since all my therms last three years plus on alkaline batteries, I'd hate to replace a device since the sealed waterproof battery failed. I wish all well with Inkbird rechargeable devices but I'm just curious and look forward with great anticipation on continued reviews with these rechargeable batteries. I have several inkbird products including their new wifi sous vide circulator just none of them have a non replaceable rechargeable battery.
