dc.description.abstract	Improvements in a split-beam transducer that is also used for surveying are sought through changes in array geometry. These are assessed through relative changes in the sum of source level and voltage response and the equivalent beam angle. A case is made for increasing the size of the present transducer array and for introducing two operating modes: (1) a central core of elements, with moderate power and relatively wide beam, and (2) the entire array of elements, both core and annulus, with correspondingly enhanced performance.	no_NO
