Ok I have several questions for y'all.
I have a Humminbird 788 and 798. The 788 has really erratic speeds when slow trolling. Example: .1 jump to .9 back to .2. Not really usable while the 798 works pretty good, might jump around .1-.2 but you can get a good average.
- Is there anything I can do to improve the accuracy on my 788?
- Can I link to my 798 and use that speed?
- Would a software update help?
- I can buy a helix 5 with gps for $285, would that be my best bet?
