I am looking for advice. I need a drone that is water proof and has enough power to drag a small rope up to 500' to 600' across rivers, lakes and ponds. I build aerial fiber optic lines and we often have to pull cables across water which requires us to pull a rope first. I have been using a beginner drone i bought on Amazon which has worked ok but its time to upgrade to something with more power. I am not familiar with which brands are good quality. Any suggestions would be greatly appreciated.
