Anybody know what the correct length probe for a Buck 80 would be? I've having problems keeping the cat in my Buck 80 the safe range. it's be an on again, off again problem. Last January when my Buck 80 was installed it came with no Cat thermometer, Buck failed to put in it before shipping. Dealer said "No problem I'll pull one from one we have in stock." Next day I was in the area and picked it up. He said the probe came from a Buck 91 (6.5 inch length) but it was the same one used in the 80 at which point I took it home and thought nothing more about it. I just learned the 91 has a larger cat, actually I think it has 2 cats side by side so it must take a longer probe. I think this would mean the longer probe of the 91 would actually touch the cat in the 80 giving false high readings. Any thoughts???? I can call tomorrow but I thought I come here first. Thanks!!
