GPS/Finder Elite 5 vs. Elite 5 DSI

[BottomBouncer]

Have any of yins seen the reviews for the new DSI fishfinder? What are your thoughts about the difference between the standard 83/200Khz finders versus the 455/800Khz units? Which would you choose? Is this a no brainer?
Thanks for your input. I need to upgade from my Eagle Cuda.

I will take a stab at this even though my electronic know-how is limited.

The deeper the water, the higher Khz is needed.

I have two elite 5s in my boat, i love them. But what i see on the DSI looks pretty good. If price is not an issue, AND you have a use for the new tech than i would go with DSI.
