Old FishHawk Thermo Troll 840 manual

[Organized Slime]

I run the older display unit with the newer, smaller clear probe.  A couple of years back I was getting readings all over the place.  It was so bad it made my unit useless.  With the help of my manual, I did a "factory reset" which fixed everything.  I wondered how many other fellow fishermen trying to nurse an old unit along in this great economy of ours were in the same boat?  I came on here and offered a scaned copy of the complete manual and was surprised at how many people messaged me.  Just thought It wouldn't hurt do it again.  I see the older units going for next to nothing so for someone on a budget it might be the route to go.  I am a firm believer having run both that the newer probe will make the biggest improvement.
