[QUOTE="Marked, post: 34933, member: 1246"] All that is required for these to work is to sit a couple of inches into the water (unless you are building the magnifying version) as the biggest barrier to being able to see into moving water is the varied reflection/refraction of the turbulent surface. If you aren't standing in the middle of rapids, you may even get away with using a scuba/snorkeling mask to do the job. Having said that, a long version may be of use in an overly bright and glare-y environment... [/QUOTE]
