phenom880

you have no idea how long this has been bothering me lol so glad we "got to the bottom" of this.....see what i did there? lol

ahahaha so true.....But it seems distance to side is not measured horizontally like i thought...so if i move my cursor over to a brush pile and it says 34 feet its not 34 feet across the top of the water when im sitting in my boat. if i was in 22.1 FOW it would be 25.8 feet horizontally .....i think ahahahahaha

k...here is a post from another site on the same question i asked.. Correct ... Targets directly under the boat will show in both left SI and right SI ... Distance to targets in SI (out to the side) is calculated as "slant range" to targets ... (that geometry Pythagorean thing) ...

thats a good point with the shadow ...i need an actual screen shot of something tall coming off the bottom that only shows on one side

what if said fish was 18 feet deep and 5 foot from transducer...i think it would show in the same spot

So in red i circled what looks to be smaller rocks the boat went right over because they show up split on both sides......the blue marker is supposed to be a 10 foot telephone pole ...you can tell depth because its roughly half way up the water column....how far away from the boat to the left is it? If it is 22 feet away like the cursor would tell you then where is all the information from 22 ft to right under the boat where the rocks are?

jfrancho let me ask you this then....if i sank a 10 foot telephone pole vertical in lake bed and the actual location was 10 feet to your left in this picture how would it show up?

then would you agree edge of the school to the right is roughly 24 ft away at its furthest point ?

so i understand that the tree in the center of picture is in about 20 fow and should be right under the boat since it spit the image..How ever if i was to move that curse, to the left to the base of the tree it would say 20 feet to the left of the boat...now if i was to move the cursor 5 feet further to the left it would say 25 feet to the left but wouldn't it really just be 5 feet from the tree that is right under my boat? This is something i have never understood with side image...someone help?
