I found a fish finder watch, can I do anything with it?
Ok so I use to have this old fish finder gadget I was given that was a green bobber (sorry if thats misspelled) and a watch which would show you where the fish were. Now I found the watch after many years and it still turns on but I am sure I don't have the bobber anymore. So is there anything I can do with the watch? It is from hummingbird.com says rf 30 smartcast on the watch, I tried simple google searches for hacking fish finders but mostly I just get hacking fish games. So if anyone knows a better website that I could look at for modding/hacking/changing this watch to do something productive let me know. I hate to throw away a piece of tech that may be able to be turned into something cool. Anyone have any ideas?
