Find the bottom in the traditional style: no electronics or moving parts, the Nantucket Sounder is rarely known to malfunction or give false readings due to junk in the water.
This depth sounder is solid bronze with a number of sensible features. The 3-lb. bronze weight (safer and more durable than lead) has a hexagonal cross-section to prevent rolling. The cavity in base can be used for taking bottom samples (useful for piloting, diving, or anchoring considerations) and the the sounder comes complete with 60 feet of Dacron line knotted every fathom, a canvas sea bag, and booklet with directions and alternate uses, and lead line lore.
