I fabricated my own scooper, and I'm using an ATpro with the stock coil and it seems difficult to detect. It also seems difficult scooop the target when I cant see where Im scooping. I was at shoulder depth of water for an hour straight.
HOw deeep do you go in the water? What might be an ideal depth. I was lake beach hunting and only found a 2008 penny, a soda tab, and a bottle cap. And they were tedious to retrieve.
