You know, I really don't know. We were fully sight fishing so I was in side imagining mode, and that mode does not display temp. Having messed with the 2 of them for about 15 casts, they were working together, same bed, not two. About 10 minutes later after we released it they were both on the bed again together. Only 3rd time ever on Saguaro, so I was just overly excited to even see a crappie. Let alone get him to hit my jig.
