Those of you that have installed the Seaclear wiring system, has anyone measured actual battery voltage versus voltage display at bow units? thinking of making a purchase. Currently staring battery is Group 31 AGM.

Yes I did, and switching to Seaclear gave me consistent voltage on all my graphs between battery and heads. I think it’s worth the money

If you can run an extension cord to an appliance you can run wire to an MFD. It’s that simple. 6 or 8 gauge wire to ( I like duplex)a 30 amp breaker/switch on the positive lead. Add a Pos/neg buss at the console. From the console buss to either 8 or 10 gauge to a buss at the bow. Done!
I buy my wire and fittings here.

If there's less voltage drop it's because the conductors are larger, more copper. Not because it says sea clear. You can get American made marine wire off amazon....buy the good stuff. IMO, you need a hydraulic crimper for 6 and larger.
You can make your own for quite a bit less. I ran one in my first boat. My second boat I remembered all it was a certain gauge Marine grade wire and connectors you can get on amazon. I made my own for a fraction of the cost. You're going to get voltage loss but with a heavier gauge air like they use, it will be minimal. My new boat I don't get much for voltage drop. The only one that has thrown me for a loop has been a Solix 15 on my dash. I have 12.7V but the graph displays 11.7-12 which is goofy. The Garmin 126 next to it displays the corrent voltage. I have even swapped the wires. I gave up on worrying about it.

The goal is to get large enough conductors to overcome voltage drop over the distance and load, and typically people aim for 3% for sensitive electronics. You can go bigger to reduce the percentage of drop, although it comes with the cost of money and weight. Depending what you run, 10 ga to the bow is fine for few and smaller graphs while larger graphs and more graphs likely need 8 ga.
