Treasure is where you find it! Go early in the morning.
The bigger the beach access parking lots the more people.
Beach fronted hotels with beach bars are VG.
Towel lines and beach pathways are good.
Most beaches are hit hard by locals, in the early morning you can get a good idea who's out there and where they detect. Sunday & Monday mornings have seen the bigger weekend crowds. If you see a lot of others detecting, don't waste time digging deep targets, you'll cover more ground and pocket more targets picking fresh drops before the crowds arrive.
