I have two pretty much brand-new humminbird 1199 KVD units. I am considering upgrading but have no idea what something like these sell for used. They are hardly used and in perfect condition. Any advice?

Generally they would go for around $100 a piece, but since I like you, I'll take them off your hands for $400.

I like the guy better. I'll give u 1,000 for both.

Because they say "KVD".

They sell new for around $1,000-$1,100/piece. Their worth has dropped significantly because of the Helix units.

You guys are awfully generous!....lol. Like I said, just curious what the toughts are.

Were seeing there sell 600 ish a piece. Hard when the new 9 and 10s are 1k to 1500 and alot better quality. Bring them babys up to boris Marine and were take them as trade towards your new stuff

ill take them both for a fair price,,,PM me

Does the HB1198/1199 transducer work with the new Helix and or Onix ?

Helix yes, Onix no

Thanks 44 Diesel for the info.
Is the Helix a big step up from a 1199 ?

Brighter screen contrast, I believe also a higher pixel count in the larger units with the HD unit.

Yes , but I wouldn't trade the 1199 for anything less than the Helix 10. I traded my 1199s for Helix 12s. The Helix 9 10 12 also have auto chart live

Not familar with autochart.

You happy with the switch to the helix units? I love my 1199's. Just concerned that if I don't swap them out in the next little bit they'll become obsolete.
