In the 2 photos below, you can see that the Thermocouple for the Silverton 620 is vertical with no other screws nearby except the 2 screws securing the thermocouple.

Both of those things make it difficult to place a 3rd party probe nearby the thermocouple to compare the ambient temperature.

Also in the 2 photos you can see where I placed 1 probe from the Inkbird IBBQ-4T using a Probe Grill Clip.
I chose that location to use up as little grill grate area as possible & also to keep the probe out of the way of the meat, etc.

My concern with that location is whether some cool air may be leaking in from the corner of the grill cover.
But, I also did not want to get the probe too close to the very hot side wall.

With the Inkbird IBBQ-4T probe at the location shown in the 2 photos, it registered the ambient temperature to be 25 - 28 degrees less than what the thermocouple registered.

There are several threads where it has been suggested that you can attach a strap to one of the probe screws and then attach your probe to that. Here is an example of a strap:

I believe I have seen every photo there is here.

None of them specifically show the vertical position of the thermocouple of the Silverton 620.

My hopes in starting this thread was to get some input / photos Re the suggested placement in the Silverton 620.

I don't want to have to reinvent the wheel if I don't have to.

The premise would be the same whether the probe was vertical like hours or horizontal, right?

Not really.

As you will see in the photos, the "vertical" thermocouple has a "shield" around it.
I assume that is because it is so close to the metal side wall, it needs to be protected from reading the higher heat radiating off of that metal side wall.

A "horizontal" thermocouple would be further away from that wall.
All of the photos I have seen show that.

A "vertical" unshielded / unprotected probe tip would also be that close to the metal side wall & would not be registering the correct ambient temperature of the interior of the grill.

My thought is that I have to bend the strap to have the probe in a "horizontal" position & far enough away from the metal side wall, but still in the general vicinity of the thermocouple.

Looking for a metal that would be harder to bend the way I need it, but it would hold that bend.

It appears to me that it is easier to add a 3rd party probe next to a "horizontal" thermocouple than a "vertical" thermocouple.
