Guys,
I am getting crazy down temp. reading with my fish hawk. I am running the new x4 probe also. Readings are from 17 to 90. I have to watch it for awhile and guess what I assume to be correct. I have tried the probe on different riggers with the same results. The down speed reading seems to be ok. Batteries are new in the probe. The display is wired directly to the batteries. The 840 display is mounted under the hard top ceiling on the port side. Not sure what I'm missing. Thank you in advance for any insight.
