Just behind you!! :D
Ok, we've got a transom mounted transducer, I'm driving the boat and the Lowrance is just starting to show a stump, drop, brushtop, etc. Where is the dang thing? Under me, just in front of me or just behind me? I mean, it's like cone signal - isn't it? Or is it like hand grenades - close counts!!!!!??????

I would have to say just behind you, as you see it appearing on the screen you have just past over it. Just like the TM, standing on the front you are standing on top of it as you past. Yes it's a cone but depending on how deep the water is depends on the width of the cone.
Thanks. If you think education is expensive, think about how much ignorance costs!!!!!!!!!!!!!!!!!!!
Not necessarily behind you. It depends on how deep the water is at that moment. If you were in a 10 foot boat with a 20 degree transom mount xducer and you were in 30 foot of water , it could be in front of you.

It also could depend on how fast the boat is moving, and how fast the chart scroll speed is set to.....I think..
It could even be in another lake, in another state.
(especially if you never turned the simulator off like me)

Play with it. See it on your screen, drop a bupy. Turn around come back across it, see it on your screen, drop a buoy. Turn around cross it at right angle, see it drop a buoy. Keep doing this and you should have it surrounded by buoy. just like baseball. Practice practice practice.
Lowrance has a great tutorial on their site: http://www.lowrance.com/en/Support/T...onar-Tutorial/
A simple explanation is to imagine that your transducer is a flashlight. Close to the transducer, the beam is small. Further from the transducer, the beam is wide. In deep water, the beam is much wider, and may extend in front of the boat. Here's a good image from Lowrance's tutorial
This shows two things: First the beam spreading with depth. The second thing is that as the fish gets further from the center of the beam, the distance from the fish to the transducer increases, while the strength of the signal it reflects decreases due to the characteristics of the transducer. That's why the fish shows up as an arch. When the fish is at the edge of the beam, the return is weak and further away. As the fish goes toward the center of the beam, the signal shows as closer and stronger, then the signal weakens and shows further away as the fish moves back out of the beam.
