One day my family was getting off the beach and when we got to the car we were still loaded with sand. I took the extra bidet I have stashed in every car (yes, every car, you've read the other descriptions, this should not surprise you), popped it on a water bottle, and rinsed off the sand.
 
We did not go in the water that day, but after our next outing using it to rinse off the salt from our bodies was the next logical use for it on beach days.
 
As a parent of two kids, there was just never a way to get the sand out of those cracks on the kids. I wish I was packing a Holey Hiker back when my kids were little.
 
"Need to rinse sand off your feet after the beach? Need to rinse a saltwater fishing reel? Need to blast the rear backup camera to get the mud off of it? I used to carry a garden sprayer when I car camped. Not anymore." D.R.
 
Personally, I think this is the most underrated bidet in the lineup. I realize that most people buying a bidet will not be going to the beach, but it's best to be prepared. The garage has a version for every human situation. This one is for the humans who end up sandy.
