The furthers we tested it has been to the limit of our fishing reals, close on a kilometer away. In theory it will go to the limit of the drone’s range it self. This is due to our design which eliminates any interference with the drone’s light-bridge communications system.Additionally keep in mind that the line itself also has resistance through the air and water and as such the further you fly bait out the lighter the load should be and the thinner your fishing line should be.We have successfully and repeatedly taken 500g loads out over 500m with 200m of 0.5mm mono followed by 0.21mm braid.
