[PSUBS-MAILIST] Digital Depth gauge with secondary display to passengers

[Lasse Schmidt Westrén via Personal_Submersibles]

Hey Guys,

http://www.ebay.com/itm/G3-8-Digital-display-pressure-transmitter-4-20mADC-sensor-stainless-0-40bar-/331562111499?tfrom=231569857640&tpos=top&ttype=price&talgo=undefined

I found this cool type of gauge that shows pressure in a simple way, and
has the ability to send the data to a secondary display.
I can´t figure out what kind of secondary displays to use, I´d like to put
a display or two in the passenger compartment for my passengers to see the
depth, and maybe a display all the way in the front of the sub.  Anyone up
with a solution?

Cheers, Lasse
