Maybe I can use a compass I already have to help me figure out if the electronics will affect it. I'm not sure I want to buy one just to test it out. I'd like to have a compass because sometimes the GPS is less than accurate showing my direction of travel. I'd also like to be able to tell how much I am swingng at anchor. Of course for emergency navigating as well.

Gps, at rest, will not show you an accurate heading.  At slow speeds, the heading will sway quite a bit unless you have a higher-end gps with external antenna/fluxgate compass.

Nice setup.  Way to avoid goop or silicone to hold the ducer down is to flip the mounting bracket & mound to the lid of the box you built.  Bam!  Nice work.

Thanks guys  for the great ideas, and so do I fill this box with water when I'm done?

Yes

It is sealed for saltwater.

This  will make it so much easier for lake inspections. Not having to worry about opening a hatch and the inspector finding some water residue.

Think he's talking about the drive unit

It's done on boats quite often however boats generally use a larger compass with better dampening, etc. Shouldn't have a big issue but test it out before mounting.  Watch the dial as you place it closer to its mounting position & see if there's a deviation

BF deals on TVs generally aren't worth it.  They are usually stripped versions that are only available for BF.  I've found far better deals as Open Box @ Best Buy usually after Super Bowl time.

You do not put the files on the navionics card.  There is a high chance you will corrupt the navionics card files.  The Genesis files must be on their own, blank card.
