Shoddy troubleshooting video, but might be interesting to those in the industry :)

Lithogen (my small business up in Canada - shameless plug) occasionally adds a cool tool to our rental fleet. We just added the RD510 acoustic pipe locator (great for plastic pipes!), which is a combination of a "water hammer" source and a single geophone. We're still getting acquainted with it (so we can properly support it).

Here's a short video I made showing off the water hammer. Officially Radiodetection Ltd says not to use it indoors, but I really wanted to see how it worked!

Credit to the actual OP. Hopefully their marks were good!

Here is the original post I stole this from.

I've found this to be useful for those who locate water but don't know what it looks like underground.

Stolen from Reddit (not OC).

I know, I know, it's a link to Reddit...
