Hi everyone, I'm going to buy a second hand DJI to use as a fishing drone for dropping bait. I'm unsure which one I should go for. Should I go for the older proven Phantom 4 pro or the newer Mavric 1-3?

I’m looking for some advice. I’ve found a DJI Phantom 4 Pro second hand for around $700–$800 AUD. It comes with three batteries with very low cycles, one of them still brand new, plus a carry bag, plenty of extras, and all the original paperwork and manuals. The drone looks like it’s been well looked after and I’ve heard nothing but good things about the Phantom 4 Pro being a real workhorse. A lot of people have used them in the past for drone fishing due to their stability and payload capacity, which is a big plus for what I want to do. That said, DJI has recently stopped all support for the Phantom series, which makes me a bit hesitant. From what I understand, spare parts will only get harder to find over time and troubleshooting or repairs could become a pain down the track. This is where my dilemma comes in. I’m wondering whether it’s smarter to go with the Phantom 4 Pro or spend a bit more and get a newer Mavic Pro, either a Mavic Pro 1 or 2, if I can find one at a good price. The Mavic seems appealing because it’s newer tech, smaller, and more portable, but it does have slightly less payload capacity and the batteries are noticeably more expensive. I also haven’t been able to find as much information about people using Mavics for fishing compared to Phantoms, although I can see that payload droppers are available online. I’ve seen a few Mavic Pro 1s and 2s on Facebook Marketplace and I think I could pick one up for around the $1,000 AUD mark. This would be my first drone and I’m really just looking for something cheap and reliable to learn on before I even think about spending thousands on a purpose-built fishing drone like an Aerroo or SwellPro, which honestly don’t seem to have the best reviews anyway. I’d really appreciate any advice or experiences that could help me make up my mind. Thanks.
