The two biggest challenges right now are; A) - the absence of people on the beach providing new drops and, B) - the lack of significant sand movement.
Can't do anything about about the first issue, however, the beach is still loaded with targets if you can figure out how to access them. New sand typically arrives in a series of thin layers, slowly building and crawling its way up the slope of the beach. The closer you get to the waterline the more new sand you will encounter. With no new drops being provided in this zone and the absence of significant sand movement to expose existing targets this lower beach can quickly become a dead zone. On the other hand, the steeper the slope of the beach the better the odds of success on the upper portion of the beach because sand will build up more slowly here. On really flat slopes you're just screwed until those fresh drops start showing up again or these is enough sand movement to expose those deeper targets. On the lower beach you need this same significant sand movement in order to expose the deeper existing targets that exist there as well.
The only other way to battle this new sand buildup is by knowing what portions of the beach have the shallowest shell packs as targets here will stratify much sooner and they will likewise be easier be access then those in the soft deep sand. These are areas you can look for simply by taking a stroll on the beach and probing the beach, and/or by digging a few scoops every now and then to see how deep the fresh sand is. "Accessible Hardpack"....that's what you're looking for, areas of firmer strata on the beach that you can actually access. Every beach will have sections of this firmer, shallower strata. Swinging a coil over targets you can't access isn't very productive.
