3 Therms diff temps????

Ok I have a herpstat on my rack. Set at 92 because I have a regular glass therm in there reading at 86. So I got new batteries for my coral life therm ( Probe style) Thats reading 91.6 should I go with the herpstat and coral life? Or listen the the ole trusty glass?:confused:

Glass one im guessing isnt digital but using some sort of liquid inside.

Listen to the Digital one with probe.. Being off 1-2 degrees is fine. And in mean time, hop on ebay and pick up a $20 infrared temp gun

Yea its not digital. I was looking for a temp gun at the show over the weekend but didnt see any. I was thinking the herpstat and the coral life being within 1 degree of eachother would be the ones to listen to. Just wanted to get some other opinions.

Also you can get temp guns at auto part stores.
