Hi all. I am brand new to drones. I am about to purchase a Dji Phantom 4 with a number of accessories which include flotation and the ability to drop items at long range. My requirements center on fishing. The main purpose for the drone will be at assist with the spotting of fish near the surface. I am based in Cape Town South Africa and we fish for Tuna off Cape Point (up to 100 miles). Sea conditions can be from quite calm and "glassy" to really bad. I clearly will only use the drone during acceptable wind speeds. I am curious about the return to home feature as being on a boat "home" is unlikely to be the place to return to unless it is a GPS location which is updated frequently - any thoughts and or suggestions please? Last but not least I wish to order in one package for delivery to Cape Town. Can anyone recommend a suitable competitive supplier who can offer this facility and I can communicate with to ensure the complete set of my requirements are gathered together and shipped as one package. (to reduce the shipping costs which are high to South Africa) Many thanks - I hope to contribute later with some of my exploits and learnings.
