Topic: Replace 597ci with what Helix model?

[country water]

I have a 597ci that has a bad GPS (for the 2nd time).  The cost to fix it is $300 which is about the same price as a Helix unit.  My question is what model do I choose for a direct replacement?  I don't want to re-do the transducer as the boat is on a lift.

If your model is the 597ci HD Combo (2d/GPS)

The Helix comparable would be the Helix 5 Sonar GPS ...
