structure

This might seem silly but I just wanted to check to me this is structure but the wy the sonar picks underneath it kinda makes it look like a mushroom this is from a raymarine A70. its not just a big dam piece of weed right ? :)

 I am no expert but the left is showing a rise around 6m from the bottom and the right it is not connected to the bottom.

My very limited knowledge would say it is fish is it always there what have you caught.

rise and weed

Tue, 2011-01-04 20:45

i would guess from what i can make out on the picture   LHS is theres a 6mt pinacle with bait fish /fish on either side of the lump , the RHS appears to be on bottom lock ?? as that wont show any rises but still should show the variance between the bottom and the fish schools, you apear to be on Auto as well i would take it off and drive the unit on manual,   also please pass on the co-ordinates and i will have a look with my sounder on the wekend and let you what i find   LOL
