We rolled into the hoard of boats in the 40-60 foot of water area and though the sonar showed promise I wasn't catching anything. I heard a few people talking here and there the same. Didn't stick around very long. Did way better in the deeper water. Been a looooong time since I last saw a boil...
455 is for down imaging and or side imaging purposes only. More than likely the only setting on yours. My front 798 SI/DI unit is 455 kHz only while my console 898 SI/DI is 455 or 800 kHz. 455 kHz is more or less all that I use. It covers 180 degrees (side imaging) and is less picky setting wise. 800 Khz is only 130 degree wide and can provide a more detailed picture. The newer 899 version of my console mounted 898 is 455 kHz only. I think they went to the single mode to cut costs and most don't use 800 kHz anyways.
The 200 and 83 kHz settings is your 2D sonar. I more or less live on 200 kHz since it is more detailed per se and I just like it more. 200 kHz is a tighter beam. 200 kHz is a 20 degree wide beam/cone heading down while the 83 kHz setting is a 60 degree wide beam/cone. Your depth reading on yours will always come off the 200 kHz freq and can not be turned off. The 83 kHz frequency can be turned on or off and can be set as your primary on the screen if one desires. When both are turning on that is what Humminbird calls "DualBeam PLUS". I have both on almost always and they overlay on the same screen or I can switch to a screen view that has 83 on the left half and 200 on the right half.
As far as "Switchfire" 99% of the time I run my sonar in "Max Mode". There is times for "Clear Mode" but not often. I run mine in Clear Mode when only fishing shallow water. Say less than 20 feet. Clear mode is filtered/computerized view and you don't see everything. Running in Max Mode you see everything. Nothing is filtered out. You really need to be in this mode if one wants to see there weight hanging under the boat or when one is jigging under the boat or using a drop shot, etc. If the water is extremely dirty there really isn't an option and one has to run clear mode otherwise the screen will get clobbered.
Off your manual.

[size 3][font "Calibri"]Your 500 Series™ Fishfinder uses a 200/83 kHz [/font][/size][size 3][font "Calibri"]DualBeam sonar system with a wide (60°) area of [/font][/size][size 3][font "Calibri"]coverage. DualBeam sonar is optimized to show [/font][/size][size 3][font "Calibri"]the greatest bottom definition using a narrow [/font][/size][size 3][font "Calibri"](20°) beam yet can still indicate fish found in the [/font][/size][size 3][font "Calibri"]wide (60°) beam when the Fish ID+™ feature is [/font][/size][size 3][font "Calibri"]turned on. DualBeam is ideal for a wide range of [/font][/size][size 3][font "Calibri"]conditions - from shallow to very deep water in [/font][/size][size 3][font "Calibri"]both fresh and salt water. Depth capability is [/font][/size][size 3][font "Calibri"]affected by such factors as boat speed, wave [/font][/size][size 3][font "Calibri"]action, bottom hardness, water conditions, and [/font][/size][size 3][font "Calibri"]transducer installation.[/font][/size]
