I've got guy selling 2 597ci di for $300 for the pair, seems like a good deal, very trusted guy, I want to run one on the bow, and one off the console. What I figure they're not linkable but I heard I can move way points via SD cards? Any thoughts and opinions on these ?

Yes you can transfer GPS data via memory card.

The display has the highest resolution in the industry.

It's the top of the line DI unit that is non linkable and discontinued when the 600 series was added to Hummunbird's inventory.

Awesome definitely going to pick them up then.

The price is excellent. Basically you are getting two units for less than the cost of two DI transducers.

You know your stuff !!!

I have a 597ci HD DI Combo registered in my Humminbird account to have access to the unit software for one of my brother-in-laws.

 

Register yours so you get the software updates.

Those things are junk! Give me the contact info for them and I'll make sure they are off the market so no one gets taken by this crook!

These are outdated haha I needed them

^^^AAhhh, the old Fishmark 320; what a popular unit that was. I upgraded from the same thing to a 597 Cidi on my bow and a 798 si at my console. Great deal you found; good for you. You'll love those 597's.
