Tough to answer with such little information but will try anyway.

1)My experience chirp has better target separation in water depths of 18'-30' which I fish alot
2) With my Lowrance chirp unit being able to select 105 or 107 KHZ is of value to me. The 105 to 107 KHZ range seems to be a sweet spot.
3) Used chirp units are easy to sell, compared to non-chirp

These three reasons are enough for me.

If your fishing out of Long Beach Island I would say that it is absolutely worth it.

Even an entry level CHIRP ducer/system...will show better detail.

I love it TH150M on a HDS gen 3 12.
Jigging for white bass and stripers. Note spoon at about 18 feet.

The great part about having a chirp unit is the ability to run 200 kHz non chirp ducers as well on the same unit. I find chirp is very good for soft target separation while 200 kHz non for a superior job at bottom discrimination. Best of both worlds.

I put a very modest Lowrance chirp unit on the bow of our bay boat, with the transducer on the trolling motor. When fishing for sheepshead on the gas rigs in Mobile Bay, which are depths of interest to you, the target separation is markedly better than with the non-chirp unit it replaced.

CHIRP it is. 300 or 600 watts for water under 75'?

Not so much the wattage... but transducer selection.

Do you want side or down scan?

Just down scan, not side.

For years it was believed CHIRP had to be expensive and was just for very
deep water. NAVICO and others certainly proved that was wrong. HDS with
the low cost TM150M transducer gives me the images I want to see.



But then the very low cost "skimmer" transducer doesn't do a bad job either.
It all works and doesn't have to be so very expensive!!!!

I am getting the same images with my Evo3 and TotalScan chirp. Has any one compared the chirp TM150 and Total scan chirp ducers side by side in this depth ranges?

S5100 with B175H-W at 250 kHz fixed frequency is by far the best I've seen at 30'. Sorry I don't have any screen shots since I'm very seldom fishing this shallow.

I fish out of LBI. I’m interested to know why you think so.

The target separation will allow you to mark bottom/ flat fish very well. You will also be able to differentiate between bait and target species.
