Dayu Electronics: Which Frequencies to Choose for a Single-Beam Fish Finder

　　Which frequencies are best for a single-beam fish finder?

　　For general use, two frequencies are sufficient, such as a high frequency of 200 kHz and a low frequency of 83 kHz. The angler can then choose based on conditions: if the water is deep, use the low frequency for detection; if the water is shallow, use the high frequency. In water, the lower frequency of 83 kHz can detect farther than the higher frequency of 200 kHz, typically reaching depths more than twice that of 200 kHz.
