"There is water at the bottom of the ocean"
I have a Zircon water level that I haven't used since getting freaking 'laser beams'
It's actually really useful and more accurate than most lasers at longer distances. It goes around corners too.
It came with about 25' of hose and I added another 25'. Runs on a 9v battery. Two one quart water bottles and a bucket to keep it all in are included.

It's not a super precise level but good enough for fence posts.
Will randomly pick a winner on Saturday evening from those that respond. Would rather meet around Tacoma but am willing to ship on your dime. Minus the bucket it should fit in a large flat rate box.
