Blue Sea 1732 Mini OLED Panel DC Ammeter

Have mine mounted down below in the saloon, as I don't need to see my power draw when on deck (I know the windlass is high draw). It's mounted in one of the 4-hole panels sold by Powerwerx, and it stands a little proud from the hole/fitting.

The depth of the unit is perhaps a little on the short side, compared to other fittings sold by Powerwerx; this may catch you out depending on the thickness of the panel you're mounting it in to.

Shunt appears to be of decent quality as well, though the take-off wires you'd fit to connect to the ammeter may end up in front of the mounting screw holes. I mounted mine with the take-off machine screws facing down, which has proved to be inconvenient when trying to re-arrange the wiring in the locker; easy to undo and flip though.

Talk about false advertising -
This display looks great in indoors room light - but, fades to barely legible in outdoors daylight.
I paid good money for ammeter & voltmeter, and would have been happy to do so if they had lived up to the hype.
Don't expect to be able to read without shading meter with your hand.

Blue Sea Systems makes nice products, and this is one of them. The OLED looks great, and I particularly like that it distinguishes between energy in versus out with a signed value.

My only concern is how well the display will hold up to abuse. I'm particularly concerned with the faceplate becoming detached in heat and/or humidity. I wish Blue Sea had avoided using a faceplate altogether. Just print the lettering right on the plastic chassis. Perhaps the faceplate makes it a bit more splash proof and protects the OLED. Whatever—I still wish glue/epoxy/adhesive wasn't involved.

Note also that this product uses a mountable external shunt block that is about as large as the display component itself. This makes the wiring more complicated than simply source in, load out. As space was a concern for me, I made the shunt block (which is mostly a hunk of metal) do double duty as both a shunt and a ground junction block. To accomplish this, I simply had to replace one of the short M6 bolts with a longer one to accommodate all my ring terminals.
