The first one is done with a little help from mother nature"wind" and is simple and consists of a spare spool of line, a clip on swivel and a paper plate.
Simply puncture a small hole on the paper plates edge as far in as possible then clip on the swivel and tie to a spare spool.
Next you place the plate in the water with your choice of bait or lure on it and let the wind take your bait-lure across the lake as far as you want it to go by removing line with your hand from your pole-reel and from the spare spool giving slack for the plate to be carried away by the wind.
Then simply pull your lure off the plate then retrieve the plate and fish away..
The second one is really easy and only requires that it be done at a lakes bend and that there is open shoreline around you.
Find a spot on the shoreline that is clear of brush and place your bait or lure on the ground with the line going into the water then simply walk the lakes bend while free spooling line into the water along the shore as you walk untill you are on the opposite side of the lake then raise your rod and with a few good swings the slack of line along the shoreline will straighten out and bait or lure will be pulled into the water with your retrieve going across parts of the lake you could not cast to and that then also puts your bait or lure in deeper unfished water.
GOODLUCK......FISHBONES
