Only if you're talking some bay-waters or lake-like conditions. Not if you're talking about regular ocean-facing oceans. The surge of water flowing back and forth around you all the time, and utter-blindness to see where you're swinging and trying to dig, would be nerve-wracking. The amount of strength needed to wade, swing, dig, etc.... , is going to rob precious time you have to swing, retrieve, etc.... You will find yourself perpetually wating for waves to recede, and trying to keep-yourself planted in one spot, etc...
My experience is that the super minus tide days, you can find JUST as much by simply walking out there on dry land, rather than trying to fight-the-ocean.
Now if you had some sort of placid bay-water's exception, or some sort of off-shore reefs or shallows that's just never accessible via low tides or storm erosion (like in Hawaii for instance, where the tides don't fluctuate more than a few feet), then maybe that's an exception. Maybe in some situations like that, you simply have no choice but to snorkel or wade out. But it would need to be a calm day w/o surges, IMHO. For where I'm at in CA, it can actually be dangerous to try to work out the ebbing/crashing surf. I've had to do it on occassion when that's where mother natures "target line" is. But the time spent struggling to hear and retrieve each target from the blindness of the white water and tangling seaweed, is very taxing.
