Trial Run: TZ iBoat v. 2

My iPad is a veritable archeological dig of marine navigation apps. At some point over the years, I have installed just about every major release: C-Map Plan2Nav, Navionics Boating, NV Charts, iNavX, AquaMap, Garmin Bluechart Mobile (that became Active Captain), and some others lost to memory.

So having recently suffered through the battery selection process, I’d like to share in depth what I know about the multitude of deep cycle high-performance battery choices…

Bob Metcalf doesn’t deserve this entry’s title, but he’s a good sport and I wanted to get your attention. Plus, I did indeed spend a morning helping the Ethernet’s inventor get more comfortable with his extensive new Garmin system, and got reminded of several marine electronics truths in the process: Current systems can be dauntingly complex no matter who you are (or who designed them), Smart guys like this one are usually adept at…
