I've been gone for too long, you guys forgot about me! lol
Here are my old plastic tubes, I still make the 12oz version on the left and the copper tube is a new one that I made last year and it uses a 24oz bottle.
The copper version does extend half way down into the bottle, making it requires soldering and simple tools (An offset wrench or long socket.)
Both are still sold locally if you ever find yourself in Redding.
My opinion on Bottles VS Bulb VS Hand Dredge - I prefer the bottle.
I have used all 3 and own a Hand dredge as well, I just like the bottle a lot better.
I do use the hand dredge though when I have to process more material or get down into a deep crack.
Honestly, eventually you should have both, a Sniping bottle and a hand dredge.
My plastic versions dont clog because the inside gets larger as it goes through, if a clog does happen it stays at the tip.
You also dont have a problem with gold falling out like the bulb type because there is more volume in the 12oz bottle when you squeeze it than in the bulb style. It can happen, it just depends on your squeeze, how full it is and if it is at the end of the suction.
The copper 24oz version can be cut to your desired length and if you can solder you can easily reverse engineer it to make many different length versions.
I found on this design that a 12" tube is about as long as you want to go, sometimes gold doesnt go all the way through so you tilt it up.
When reduced to 10" overall length that does not happen nearly as often.
I used the copper version in the picture all last year without a single problem.
The tip of the tube is slightly bowled over to prevent clog ups.
I am not a contributor right now so please don't ask me how much they are or if I will ship one out, I want to be respectful of the site.
I will register again here next month to start selling again, I just don't have enough materials on hand to fill orders at the moment.
