What's the difference between the TP08, TP08S and TP08B?

The difference between the TP08, TP08S and the TP08B is the button layout, probe style, appearance and range.

TP08 has an older button layout, it also comes with 1 angled probe for internal meat temperature and 1 ambient air temperature probe.

The TP08S has a newer button layout and comes with 2 straight probes that can be used for both internal meat temperatures and ambient air temperatures.

The TP08B has a newer design/color and operates off of a different frequency giving it up to 500 feet of range.
