A few years ago at Keystone Dam, I started something, dont know why I had to start it, looked like a simple solution to me. Down there at the outlet, they have a guard rail and usually the water was running swift, so you needed some kind of rod holder. I got some PVC and cut it into 2 foot sections, and used 100 mph tape to tape it to the posts, I also used those sections to stuff inbetween rocks at other places. Well, I am night fisherman for cats, so I went a little further, and added LEDs these were powered by a single 9 volt battery screwed into the side of the PVC pipe, and a spring on the inside that closed the circuit when you had a bite. They worked great, the only issue I had was that when they werent running alot of water you had to have a really good hit to light up the lights. I found some spring tensioners, that would work great, just never added them. I tried everything, bells, reflective tape, just didnt seem to work good, but I tell you those little LED's sure lit up the area..... I think my total investment was about 7-10 bucks, not counting the cheap flashlight I had on hand to get the spring and other parts I needed for the trigger mechanism. My question is, is there anyone out there with a good software, that could do up some plans for me? I can e-mail you a rough drawing..... I am not looking to make any money off this, just something I can post here for everyones use.... I sold those 2 rod holders for 20 bucks, when I was down there my last time.....a guy out of OKC bought them.
