gidday folks, ive had the misfortune of having a large steel anchore part ways with the chain right at bow roller. shackle bolt snapped!! i watched her drop into about ten meters of murky water in bay of islands. dived on air three times to no avail as zero visability. i have about a 50 m circumferance area where it is. any ideas on how. im thinking grapple? sharks in area and no viz means diving out. soft mud bottom.
would a good fish finder pick it up?? thanks in advance
