I've been searching for a way to build my own ROV, since for some reason I just can't take my mask off during the Open Water dive tests, in the pool no problem. Go figure

So the all mighty Google has lead me here.
The main reason I would like to build a ROV is that I would like to join my Uncle on his dives (no Nathan Fillion is not my uncle).
My uncle is an diver photographer, some of his photos have even been published in a few magazines https://www.flickr.com/people/roncasual/
Some things I would like to include is the ability to take readings with various sensors, including a geiger counter with the ability to recors and overlay the info on screen.
On a side note, anyone else in Vancouver British Columbia Canada doing this ?
