[TG] [TG11] e127/ B744 can't see fish

[Captain Starbucks]

Hi,

I've had this unit installed on my boat for about 4 years. I've never been able to see fish unless they're big and right under the boat (albacore). I can see the bottom just fine, even at speed but after watching countless hours of video's and countless hours of trying to adjust everything, I never seem to have any luck. I've also just left everything on Auto and still no luck. I know there are fish there because my catch rate has been good. Once I adjust the sensitivity up high enough to see the downrigger [censored] (12 lbs at 55 feet) the screen is so cluttered up I wouldn't know a fish if I saw it. I'm expecting to see 5-30 lb salmon.

I operate in saltwater in the Pacific Northwest.

Can you provide any clues as to what is wrong?

Boat is a Shamrock Mackinaw 270 straight shaft. Transducer is mounted upstream of the shaft and has a high speed fairing block.
