I watched a $150 flashlight fall out of my pocket and into a rushing creek while hiking a couple days ago. I went in and searched for it, but the rushing water made visual searching impossible and I couldn't find it by touch.
Below is a photo, with the area I dropped it circled. I believe the light sank straight down, and didn't float downstream. In the circled area the water varies from 4-8 inches deep. I'd want to search an area about 3 feet in diameter.
My idea is to bring another bright light to light up underwater, and then use a plastic transparent jar/tub and half submerge it into the creek which will hopefully allow me to see the creek bottom through the jar/tub.
I've considered using a very strong magnet to comb over the creek bottom, but I don't have one strong enough that will attract the magnetic battery inside the non-magnetic aluminum flashlight body.
Are there any other ideas? Perhaps is there some sort of material I can use to temporarily block the flow of water streaming over that area?
