Selamat malam,
Sedikit koreksi dari keterangan BabyBarracuda, kerucut yang besar adalah frekwensi yang rendah (45-60kHz) dan kerucut yang kecil adalah frekwensi tinggi (+/-200kHz).

Anda benar:
"The dual-frequency transducers come with both a narrow (12°) 200 kHz and a wide (35°) 50 kHz cone angles. And the dual-search transducers come with both a narrow (12°) 200 kHz and a wide (35°) 83 kHz cone angles. Generally, use a wide cone angle (20° vs. 12°) for fishing shallow to medium depths.
The narrow cone (12°) penetrates to deeper depths, but shows less fish and structure due to its narrow beam. This only applies when comparing transducers of the same frequency. For example, although a 50 kHz transducer has a broader cone angle than the 200 kHz transducers, the 50 kHz transducer will travel much deeper due to its lower frequency transmission. "
