In these pic's I am fishing fresh to brackish water in the delta of Northern California for White Sturgeon.
DEPTH: 30 to 60 ft.
COLORLINE: 70%
SENSITIVITY: 80 to 90%,
CHART SPEED: 100%
PING: 100%
SCREEN SIZE: full
UP & LOWER RANGE: Top either 10 - 20ft. Bottom roughly 10 ft or less below the bottom.
Transducer: Stock transom 600
BOAT SPEED: 5 to 7 mph.
I was told that with this unit my target specie 4 to 6 to 10 foot fish who only feed on the bottom (hense why I decided to cut out all above screen) that a target this large would be hallow and may not have much of an arch and color wise would be full of yellow?
These pics are actual pics created after viewing my sonar video recorded trip of the night before last.
Just trying to get an idea on how to identify size of suspended objects either slightly above or on the bottom where they feed. I also want to be able to get an idea of size and be able to determine specie based on size?
In the above pic the marks are very arched and a little yellow but not a lot. Do they seem like they can be the return of a 4 plus foot fish? Also, if you look to the Right you can see my anchor drop below them.
In this pic above it appears to me to be a large group I picked up off of a ledge?
In this pic is another large mark most likely a little larger than the other 2 scenarios I anchored below and the largest of the night for that matter.
Thanks in advance. I am going from a little 7" (Lowrance 350-A) monochrome screen to this 10.4 color and I am just trying to get caught up to the new millennium. lol, ZACK!
