made in 1 meter pvc pipe , alu/resin fins, 20 m cable (for river it's suffisant), it working good, no loose signal
i made it for archaeology and river survey
next project : a double duccer as rickard done for sea scannig, and the towfish who go with this ducer is on my ead too
the polished ducer is not making good picture, i'm going to cut it to see the distance between the elements and the hull of ducer
