Tiz a high ratio surf type Saltiga lik the ones we see on TV up at 6:1 I think Bennie - the Z40, SA30,40,50,30T, all between 4 and 5 to 1 and jigging reels. Z40 a JDM. None of which sold in SA outlets I beleive.
Since read you next post - the gear ratio issue exactly the same as riding up a hill on a bicycle - the lower the gear the easier it is and you can go for longer periods. Most accomplished jiggers on good jigging reels can jig all day for days on the trot with 300gram jigs on the right tackle. With 400-500 gram jigs you will have to be down at 4 to 4.5 to 1 else you gonna take serious flak I think.
Short rods, low ratio reels with long handles - Ocea Jigger 4000P,Saltiga Z40, Jigging Master PE4/5, Alutecnos Gorilla 12C for me are the business. Saltiga Z40 even with the drag upgrade not up with the others drag wise but very comfy to jig with. Gorilla 12C with the ergo handle is superb.
