The higher the sonar frequency, the less it is able to penetrate deep or cluttered water. 83 or 50 kHz are essential for identifying large fish in water deeper than 100' for one of the small low powered ffs we use. You sacrifice resolution for range.

That's why you see guys cruising around w sonar that cost more than their kayak.
