Between different family members 3 boats I get to do a lot of fishing on them. Thing is I would like to step my game up and start using a fish finder to give me info like water depth, temperature and obviously show me where the fish are! GPS would be nice but not a necessity as I've got to keep the price low.
I am looking for a portable model, one I could easily pack up and carry from boat to boat. 15 years ago I had something similar, you could just drop the head over the side into the water and you were good to go. Do they still make ones like this?
I'm really on a budget here so I understand I can't get the largest screen size or the most vibrant display, just looking for something to get the job done. Any advice on what to look for or even better a specific model recommendation would be GREAT!
