I only fish fresh water in the fall/winter, rest of the time I'm in the Indian River/Mosquito Lagoon (Inshore-salt water) and I generally put in before daylight.
My GPS is indispensible for telling me where all the unmarked poles, shoals, and snags are located, and there are literally dozens and dozens of them.
I just couldn't get anywhere safely without it. Everytime I go out I find more and more stuff to waypoint (like that pole that was just under the surface and put a nice $350 gouge down the side of my new fiberglass boat).
What I've been doing is going out in the day and making "trails" to my favorite spots that I "KNOW" are safe to run WOT, even at night. However, have to always be cautious for crab traps and suprise debris, but I know with certainty I'm not going to slam dead head into an umarked post.
GPS = Couldn't live without it !
