When dredging in deep water and you can't quite reach when re-filling your gas tank - DON'T allow the gas to come out of the breather hole in your gas can and run down into the arm of your wetsuit. You will notice the burning sensation right away as it continues to get worse - Get your wetsuit off and wash the gas off!
Run Away Dredge
I was dredging with my partner on the river once near some fast water and my mistake was having only one anchor on a small dredge. Can you guess the rest? That's right. I came up to do something and while I wasn't looking the hose of my 3" Proline caught the current and pulled the dredge into the fast water and rocks. It was kinda sinking for a minute or two. It was very difficult to say the least but I pulled the dredge back up river to where we were. I was standing there trying to catch my breath after all that when my partner came up from dredging. I was grateful that he missed the whole thing. Unfortunately it was the day when they were shooting a video about prospecting and they told me they got the whole thing on tape. Now I can't even lie about it! Always use two anchors when dredging near fast water.
We had been dredging in some fast water and I had 80 pounds of weight on and I stepped off of a ledge at a new spot and down I went 14' and my feet got entangled in in some tree limbs. I had the hose of my 3" Proline in my hand so I climbed up it to my dredge. I was a little panicked and was breathing heavy. I knew that if I dropped my weight belt that I might never get it back (at least that day) . I climbed up and as I reached up to grab on to the back of my dredge my weight lifted the front of the dredge out of the water. Well, I had a Honda 5.5 with the Low Oil safety feature on it. I must have been low on oil and when I tilted the engine it quit. So there I was struggling to hang on to the dredge, under water and quickly running out of air. I made it around to the front of the dredge. I was in a back water area and there I was going around in circles. I finally made it out. Quite a sight I am sure. The hole I stepped in was 18' deep at its lowest and I have since found good gold in that spot. I bought a 4" shortly after that. Always make sure you have full oil.
Put a thin layer of wetsuit repair glue on the areas that will get worn from dredging and you can make your gloves last for years instead of weeks.
