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...
