See full version: Selecting a Transducer
As the technology of sonar (an acronym for Sound Navigation and Ranging) has developed, prices have dropped dramatically at the same time that choices have widened. What once was a simple electronic device meant to determine the water's depth now has numerous capabilities to find fish, scan the bottom for obstructions, or create underwater maps.
Long-stemmed bronze transducers are still best when mounting through the hull on a boat with a very deep "V" or high deadrise angle where fairing blocks must be used to keep the transducer close to vertical. [links]
A narrow beam of 10-15°, on the other hand, concentrates its energy on a section right below the boat. When looking for individual fish or bottom structure in shallow water (say under 100-200'), a narrow-beamed transducer should be the first choice. Note that there is a certain amount of correlation between a transducer's frequency and its beam width. As a general rule, lower frequency and a wider beam angle tend to go together while higher frequency and narrower beam width are usually companions. This makes sense, as the latter makes a great depth sounder while the former is an obvious choice as a fishfinder. here
* Stainless Steel Back Plate: now available and highly recommended for hard to reach / tight to work in areas.
