Re: clamp on manual downrigger
I have 2 Penn, 2 Scotty and 1 Lake System downrigger, I also had 2 of these Lure Jenson models.
The spool the wire wraps around splits in the middle, the crank handles are held on with small split pins, these pins fail and the handle isn't connected to spool when this happens, I carried a bunch of small nails for backup. There is no clutch, the stop just wedges into the spool, it sort of works, but can't be adjusted and when its needed it contributes to the spool splitting. The rods its made from are too small and start to bend, so after a while you need to switch sides of the boat so they start to bend back the other direction. The depth counters stop working after a short time. This all happened in about a year and a half, the Lake System D/R is about 20 years old, the Penns are about 15 and the Scottys are 5, I've had no problems with any of these.
In my part of the world almost every boat has downriggers and the L/J models are very rare, in fact you can go for years and never see them on a boat, the L/J units were even made here too.
