Re: I need ideas on how to measure prop rpm underwater

Interesting I can think of underwater motors this would be useful for...
Other things may be underwater turbines for electricity generation in which case the entire unit may be submerged ...
Hrmmm yes this would likely be best done in a water tight enclosure but there may be other reasons to want one that will function underwater I wonder if a plexiglass enclosure all sealed would allow it to get an accurate reading as I am sure they make water proof terminals that you could use for your wiring if need be if you mounted the case in the correct spot maybe you could get a reading.
Maybe they make an underwater tachometer ? might be a better route?
