Condar and Insert

So is there honestly any benefit in buying a Condar cat probe for my Blaze King insert? I am looking at the one with the numbers on it, for curiosity mainly and for helping with directions to my wife.
I am also curious if anyone has the digital catalytic monitor that they sell, or if it will even fit my stove?
I am really looking for input/feedback from owners of my insert but all input is obviously welcome.

Personal preference I guess. Some people find the BK thermometer without the numbers works just fine and others like me want more detailed info. The Condar digital probe would work but you would have half the probe and wire hanging out the top.

Thanks for the input Todd.
