FISH-FINDER. Bendix Aviation Corp. last week announced a 15-lb. electronic fish-finder. Similar to larger models used by commercial fishermen, Bendix's cigar-box-size sonar helps pleasure boats find fish by bouncing high-frequency sound signals off the ocean floor, recording objects denser than water. Price: $400.

SILVER LINING. J. W. Wolfenden Corp., Attleboro, Mass., offered a new silverware which is kept tarnish-proof by a coating baked on the silver. Price: 10% above regular sterlingware.
