Review on Wire Threader Fish Tape with Steel Rope 20FT(6M) for Pulling Wires Through Walls and Cable Fastening by Zach Clements

I had to build a 15ft fish on my boat, engine bay to engine bay (catamaran). I could see all the way. The problem is that the fish is reeled in to be sent to you and the reel/spin doesn't really go anywhere. won't go! It cannot be made straight, it is always curved. So you can't move it straight, it will bend and go the wrong way or get stuck on something. maybe with dozens of counter-curves at extreme angles to make it straighter, but it's never straight enough to go where you want it to. So good luck on the wall! Or wherever you are. blind. I couldn't get it to work when I saw the end! Bad tool.
