Lawrance Elite/Hook 4 compatibile?

Hey guys/gals,

Wanted to get an extra transducer and power cable so I could use my fish finder on my back up kayak as well as my primary one.

Went to West Marine and naturally walked out with a entire new set up. I suspect these two have limited compatibility and that I should probably mount the newer one on my primary yak. So my questions are:

Can I use the newer head unit with the older transducer?

Can I use the extra Navionics gold chip I got with Elite 4 HDI on the Hook 4 instead of the Nautic Insight Pro chip? And if so is it any better?

Almost exclusively fish the Ocean or Bay but was second guessing my choice. Was thinking that if the old card would work on the new unit perhaps I should have gotten the Hook 4 with the lake maps instead?

Appreciate any advice.

If you call Lowrance, like I did, they'll tell you they are 100% compatible.  I use both cables from an Elite 4 with my HOOK 5.

The cards work with both, too.

Yup, what he said. Lowrance uses the same transducer for the 4" all the way up to the 9". Plug n play. As for the cards, make sure the software is up to date on all units and try it... I'm not sure.

I've moved the Navionics card between the Elite and the Hook as a test and it works fine in both units.

Thanks guys this is awesome news! Just in time too, was about to pull the the old transducer out and relocate it but sounds like it's even simpler than I thought.

 I'm starting to  think about fishing some of the great lakes we have access to. Anyone have an extra Lake Insight Pro chip they would like to trade for my extra Navionics gold chip?

Does the lake chip have something over the gold chip for California lakes?

I was told to make sure the fishfinders are OFF when you install or remove the nav chip.

Thought that the lake specific card would have more details but after doing a bit more searching it looks like I was incorrect and that the Navionics chip with an update is going to have the most details.

Guess I'll just stick with what I have.

Bah!  I was --><-- close to saying "Hell yeah, I'll trade you!"
