The 83 KHz has better fish discrimination but the 50KHz will give you a better look at the bottom as you go deeper when the 83 starts to fade out
It is a 26.087% difference between 50 and 65
1.95 MHz 1,950 KHz 1,950,000 Hz
It is: 50-37 = 13
it would be -50-100 =-150
The difference between 50 meters and 5 meters is 50 meters - 5 meters, which equals 45 meters.
50 - 11 = 39 The difference between the two is therefore 39 centimetres.
The difference between the two is 20 percent.
50
30
Majority > 50%, Minority < 50%
the difference is 50 degrees
Roughly the range of frequencies between 50 KHz and 100 GHz, give or take an octave.
