Default 1kw for600w

I am able to swap my Standard Horizion DST526 600w for a DST528 1kw and some money.
1. I fish in 60' or less
2. I see on Airmar site that 50/200 50 gives more dia at 50' than 200 at 50'
3. I use 200 freq should I use 50 freq
4. What is the advantage of 50 over 200 or vis versa;
;?;?;?;?;?

Many fisherman use both...by using a split screen.
Best of both ranges and cones.

The 50 kHz cone on a B60 for example ..at 50' is 41' across.
The 200 kHz cone of the B60 at 50' is 11' across.

The narrow cone of the 200 kHz will give better detail for structure and the higher frequency is more sensitive to smaller targets in the water column.
The lower frequency 50 kHz not only has wider coverage but will have greater depth capabilty..but less senstive to smaller targets.


Small fish & bait showing more detail on the 200 kHz side.


For your depth of 50' or less then I would still use a split screen if possible.
Bu comparing both screens you can help determine target location.
If the target shows on both screens ..then the target is basically under your vessel..as it is showing in the narrow 200 degree cone area.
But if the target is showing only on the 50 kHz screen..then the target (fish) is outside the 200 kHz cone but still in the outer portion of the wider 50 kHz cone.



Strong and equal targets on both screens..theses fish are under or very close to the boat.



Here the targets are much stronger on the 50 kHz side..these are farther from the 200 kHz cone area...and farther from the boat ..and still in the wider 50 kHz cone area.

Semperfi thanks I see what you are saying I have a 12" screen so split is not a issue. Will I gain anything by going 1kw?

You are fishing very shallow....60' and less..I see no need for a 1 kw ducer as far as power is concerned....unless your aim is to give the fish blurred vision

Units to consider... a P66, B60, B45, P79 etc...then you have good cone coverage.

Ok I will keep the DST526 th. I want to try chirp I have a Elite7HDI 83/200 455/800 tm transducer. I was wonder if I can use my existing transducer and just buy a chirp display unit. I also was looking at B60 20deg t/h transducer ;?

Yes, you can buy Elite CHIRP and use your current 83/200/455/800 kHz HDI transducer.
