I got an electronics gift

[GTRIEM]

Hey guys,

Need some advice-

We have been fishing with less than up-to-date electronics for years,

a decent old garmin gps and a hummingbird fish-finder, can't really complain as we usually do pretty well.

Now for my "problem" a friend upgraded his electronics and donated his used stuff to my boat.

Its a LMS-520c and an X510c, also have the LGC3000 external gps ant. and a (i believe)200hz skimmer transducer.

Now as far as i can tell both units need a power cord, i have 1, and the 520c is the combo that the gps connects to with the "network" wire.

If i get another power cord and a shoot-thru-hull 200hz transducer, should i run the 520c with gps and sonar with the shoot-thru-hull and the x510c with the skimmer transducer off the back? Is there any reason to network to two?

FYI, the original owner really doesnt know jack about this/his stuff and I'm just trying to upgrade, if its worth the effort. Have not run a sonar test yet to see if the Pursuit hull is ok with shoot-thru.

Guess what i'm asking is - what would you do with this free stuff? do you know of a maker of cheaper power cords?

Thanks in advance,

GTR
