Semi-Budget tether advice
Im designing and building an ROV for myself, this is my first venture into the ROV world. Im trying to build a vessel capable of depths of 500 meters. i live close to Lake Chelan in Washington state, which has a max depth of 453 meters, so thats my goal.
Budget wise im trying to stay around $1000 for the vessel itself, Fortunately for me, i have access to machining and tooling to build much of the mechanical components myself. Really the only things i wont be able to build myself are the electronics, but ive got most of that sourced already. The only thing that im having a difficult time with is finding a suitable tether for not an egregious price.
My question is: Are there any suitable off-the-shelf options for making a tether capable of withstanding 500 meters for a reasonable price?
If i can make the tether for under $600, ill be happy. I know traditional copper cored wire has data loss issues at length, so im leaning towards fiber optic as it is.
