Beach recovery two rings

Received a text from John regarding three rings lost on a beach one hour south of me.  Definitely out of my area but another ringfinder who was unable to do the search recommended me .My first thoughts were of a storm off shore which were going to give the coast some big wave action and if these rings were above the wave line or not. I called John immediately and He said he was on the beach searching . I said I would be an hour .   The area was above the usual tide /wave area and John had recovered one ring before I arrived.  First sweep produced a great signal that proved to be the second ring.  Fifth swing was another that was the third.  Less than two minutes.  John was surprised I think and very thankful.  Here are pics of the rings .       Bill
