The Dipsy Diver is a trolling sinker that allows multidirectional trolling. Like all planers, Dipsy Diver is held in planning position by a lead weight. The weight isDipsy Diver Diagram molded into an adjustable base plate. By rotating this plate to the right or left, it tilts the planning surface, causing the diver to move to either the port or starboard (left or right) side when trolled. Leaving the weight at center, the diver will then track straight behind your boat. Unlike lead weights attached to your fishing line, a diver loses its resistance in the water when tripped, allowing easy retrieval of your gear. This loss of pressure or drag also provides extra sport and enjoyment when fighting a fish as there will be almost no terminal gear resistance. Perhaps even more important, because the diver loses pressure against the water when tripped, fish are prevented from gaining leverage and throwing your hook. Another big advantage ofDipsy Diver Depth Chart divers over lead weights to easily get a lure down to a predetermined and repeatable depth, is that they act as fish attractors because of their color and shape. Dipsys Divers have a removable "O-Ring" which, when in position, creates extra planning surface and can deliver up to 20% more depth. The depth your diver attains will depend on trolling speed, diameter of line, length of line out and weight of your lure and or added attractor such as a dodger. Light lines and small lures will produce more depth while heavy lines and large lures and or dodgers will give less. It also is important to note that the angle of your line from boat to water DOES NOT indicate the position underwater of the Dipsy Diver. The table should be used to estimate the true side angleDipsy Diver Snubbers and location of the diver underwater. Snubbers can be used with Dipsy Divers. Snubbers are made of flexible material and are designed to stretch and flex when put under tension. This ability gives a cushion to the shock when a fish hits your lure behind the dipsy diver. There are a variety of styles and colors. There is also a debate whether they are needed at all. Most fishermen use snubbers. The rational is simple; they might not be needed when catching 3 to 5 pound fish, but are worth their weight in gold when a 15 to 30 pound fish slams your lure. Dipsy Divers used trolling with peanut flies for spring salmon and trout are usually set to run in the top 30 feet of water. Many times the most effective dipsy diver is only 10 to15 feet down off the side of the boat and can be seen looking over the side of the boat.
