The following review was written by the editorial department of Chesapeake Bay Magazine.

Airmar designed its new P48W transom-mount transducer ($150) so inshore tournament anglers could see more fish on their fishfinder screens. The extremely wide (38-by-12-degree) beam can be manually shifted between port-starboard and bow-stern orientations. Compatible with most popular 200 kilohertz fishfinders, the P48W has a depth capability of 400 feet. Airmar Technology Corp.; 603-673-9570;
