it's been while since I replied to a thread on sdfish.org.
During summer months, I prefer to do my fishing sessions in the afternoon. When I see a series of peak high tides around 5pm' to 7pm on the tide charts, I'll hit up anywhere between the stretch of south mission to pb. I'm always equipped with three things to carry, my rod&reel, my backpack with only necessary terminal tackle for SCs as bait plus a few plastic baits as backup and my homemade SC rake that I had for over 20+ years. so far, I really never had any problems locating SCs. My experience over many summer sessions collecting SCs, has been only when the incoming tide is at least 4+ feet and when the swash begins reaching the high tide shoreline. I'll walk a long the shoreline and search for SC beds with multiple black sand V patterns in the sand, where I can see SC two antennaes sticking out at the point of each of the v patterns. When the next uprush rolls in, I'll simply drag my SC rake on the SC bed against the shore uprush or just wait and drag my SC rake on the SC bed against the shore back rush. I'll pick out the keepers and dump the rest back.
You don't really need a SC rake. For me it's just easier, but the downside is lugging it around. Using a small colander to collect SCs will do just find. I keep this colander in my car just in case.

During my last afternoon shesh, I collected a lot of dime size SCs with eggs. Caught eight BSP two were nearly nine inches and the rest were six to sub six inches in a few holes a long the stretch of PB and north mission.
So far, this summer season, I caught only couple of beans, one SNGF, and multiple BSP. I'm still waiting to land a SFC or YFC.
Tight lines!
