Tiger, wireless remote control
1.You can press "+ -" on the TIGER to adjust Fan speed.
But you can not change fan speed on handy set.
2.Both probes are same technically. The outer port is for Pit temperature, and the inner port is for meat temperature.
3.This is more a hobby than a business. If you American accept it, I will upgrade it to a formal business. So far technically it is successful, but commercial it is uncertain. I sell about 20 pieces per month. This sale can not support a formal business. Hope I can find An American partner soon.
