[PSUBS-MAILIST] 12V DC Sonar Implementation

[Private]

Hi Steve,

I find a laptop hard to imagine in a 250 just due to space constraints. I think the first thing I'd look at is whether one could interface the sonar to a tablet instead. Note that an iPad, for instance, has a 12 hour battery so you would save space, amps, and money by getting rid of the DC-AC converter.

Best,

Alec

As an off shoot to developing my K-250 electrical layout I am looking at what it would take to add (later) a sonar system based on a 12V DC system.  Thought I could get some feedback as well as provide an "example" for others considering a similar scenario.
