I bought this and began to install it but then changed the way I was going to monitor my battery system and no longer have a use for it.  I mounted the shunt to the wall and then removed it.  I have not connected any wires to it nor wired up the display.  Essentially it is brand new. Never powered up, never connected to anything.  It generally goes for about $170 online.
Specs are found here:  
DC Digital Ammeter - PN 8236 - Blue Sea Systems
I don't have the clear plastic packaging but have everything else.  The display, the shunt and the instructions.  The plastic screen film has never been removed.
It is a digital amp meter that can read +/- 500 amps DC.  
It is model 8236 
I probably will not have a need for this and it will just become part of my ever growing, unused boating pile of crap.  I would rather see someone put it to use.  It is a useful item for the boater.
The photo is the the actual item.
$85 via paypal and it is yours. I will ship it to you USPS .
