Transducer frequency

[z3bass]

What is the best transducer frequency setting (83khz or 200khz) for for both the bow and console units. I am fishing primarily 20 - 60 feet deep.

Thanks!

When you fish 20 to 60 feet, your transducer frequency should be set to 200 khz. From 60 to 70 feet or so, you can change back and forth between 200 and 83 and see for yourself which frequency is showing the best detail. When you get into water deeper than 70 feet you will normally find that 83 khz will give you a better picture of the bottom.

The higher the frequency the better the detail but the easier the sound is absorbed by the water. This is why a lower frequency like 83 khz will show the bottom in deeper water but not in as much detail as you saw in shallower water with the 200 khz.
