True but a little unwieldy to carry around on the boat.

Actually I've not had a reason to use mine on a boat but I have an old
tektronix 305 portable that has rechargable batteries plus terminals to
accept dc external power anywhere from 9v to 32v. And it's fairly small for
a crt scope. All solid state except for the crt and fairly resistant to
bumps and bangs. Tektronix always was my preference for scopes.

Nothing is better for testing the input and output of transistors and
the cpu of an engine... I used to be able to take a quick look at a
spark plug patterns and tell you rich, lean, open, dead, etc. in a
matter of seconds. Some of the guys would have me poke my leads around
under the hood before they started working on certain runability
problems... Saved them a lot of time.. The other thing I could really
read well was the tail pipe gas tester.. Between those two inputs, I
could really point someone in the right direction...
