Just made about 10 dozen myself with what I call texas rig style (weight does not slide, decoy is attached to swivel that slides up and down the line, so decoy slides up and down, self adjusting) with loops on both ends and am changing out all my shallow water dekes. So easy to put out and pick up.
Bought all my supplies on ebay
400 lb mono
cheap aluminum caribeners
cheap floats (to keep from dropping caribeners)
crimps (make sure will fit mono)
biggest swivels you can find
good pair of crimping pliers
just remember to allow for length of loops you make on ends of lines when measuring or your lines will be too short.
Add at least 4-6 inches to the length you want the lines to be for each loop end when cutting- if want 48 inch lines, cut the mono to 58 inches.
Also cut the mono with razor blade at angle instead of using cutters so it will slide through the weights easier.
I had fun making mine and would be glad to offer advice to anybody wanting to make their own.
