Jet Divers are a great tool for controlling the depth of your lure while trolling. I've never used them for small fish, mainly big trout and salmon, so I can't speak to how much drag there is when you've hooked something that is on the light side.

However, you can minimize the effect of the drag by rigging the diver off a slider. Rig it just like a free-sliding weight with a swivel or EZ Glider on your main line and a short dropper to the Jet Diver; in addition, the freedom the diver has makes it swim from side to side like a Hot N Tot. You won't feel nearly the resistance with this set-up unless you're using the really big divers. The 50 will drag your boat backward-- almost. Good luck, Keith
