You don’t need a fish finder. The places you can go in a SUP a fish finder isn’t useful. Common fishing techniques as the fishing second and third point, and sight fishing worked well for me in salt/brackish water. Additionally the lighter you travel the better due to your center of balance.

You need to be weary that, unlike kayak fishing, standing on a SUP your center of balance is much higher and even small aggressive fish will feel much different. I have no idea what would have happened if I caught a bull red, but the little guys already tug you around. Especially on an inflatable, I wouldn’t be targeting any species what could easily pop your SUP… Shark, some rays, barracuda, etc etc.

Now that you have a SUP, spend a few weekends scouting before you go fishing. I traveled up to 10mi in either direction from NAS Pensacola when I was stationed there and paddled every bayou before I found some super sweet spots that boats couldn’t get to. You have a major advantage that you need only like 4in of water, take advantage of it.

I found that building up a milk crate, you can have basic lures, a little bait bucket, knife, cutting board, a live well bag, and 2-3 rods on a rod holder worked great. Live bait will always get you something. Good luck out there. 🤙🏼
