Kristal Programmable Electric D or SD Series Fishing Reels
All of these reels are programmable versions of the 600 Series, ie: D models, aka SD models. These reels may be programmed for Auto Stop, as well as for automatic jigging. Each reel features a programmable digital line counter that allows the angler to know how much line he or she has in the water. The D Series does NOT have the manual override handle. If you are looking for both programmable and manual override, look to the DM series reels.
All of the programmable D & DM models must have the variable speed control option.
