Ok thank you. And thank you for the info.
I am finally getting back into fishing after about a 15-year hiatus. Starting to fish the areas south of the JFK causeway (between JFK and Baffin Bay) in Corpus Christi. I was looking for some good maps of the bays that provide depth/bathymetry info, mostly to keep me from running aground. I was hopeful that by now (2021) that "there would be an App for that" to get that type of info on my phone, but I haven't found any solid info online. I have a GPS on my "new" used boat and I am starting to learn that unit as well. Looking for any input from the group on good Apps for maps. We're mostly fishing for trouts and reds FYI, but with young kids we'll be happy to catch most anything on some days...
