I'm not sure kosmo...I guess we will learn more as customers start using the units and reporting in...

Shellback is trying out his Garmin 70dv this week at Kerr Res in Virginia. He will probably post some pix when he returns home Monday.

i have the Garmin 70DV, with 2D sonar and down imaging, no chirp transducer. The chirp SI transducer comes with their black box add on that gives side imaging. Not sure if I will be going that way or not. here's a few screen shots I took last week. The fish were biting in water 5-7 feet deep, so I didn't spend much time fooling around with the new unit. The old bridge shots were taken in some choppy water, so I think the clarity was effected. I think I am going to be very happy with it!Attachment 159862Attachment 159863Attachment 159864Attachment 159865

I do not see much difference in showing similar steel structures by Garmin 70dv and Humminbird 385ci DI:

They are very similar. My first picture has much crisper lines than the bridge shots. I was on a mission for fish'n, and ran out onto the open lake to get the bridge shot. The water was choppy from the wind, and also me circling to find the bridge. Not sure if that effected the sharpness of the picture or not. They were the first screen shots I took with the unit and the setting are what are default to the unit.

I think the default is the "ultra" or something like that. I'll have to get on the boat and power it up.

I was having some blurring with my Airmar P66 2D. Fishton told me to slow the chart speed and it really helped.

Just a thought.
