Come out from under your bed today...... DO SOMETHING!
Try to get as clear an idea as possible as to WHEN it was lost. Match that to the tide tables. Doesn't make sense to look 50 feet too far down the sand if that was all underwater when he lost it. If it was lost IN the water, you must HURRY! The ring will "dive" deep quickly and may already be too deep to get a signal. Use a sweep right above the sand for max depth. The odds of finding it, even just one day after losing it, are stacked against you. Good luck! TTC
