Gene,
I have a couple electric reels that I use for halibut. One is an electra-mate 612H. The other is homemade from a Lincoln Continental power seat motor. They are both mounted to 6/0 Penn Senators. Both work really well; the LC model is a little slower but has plenty of power.
These reels come in really handy on the Oregon coast where we fish at 100+ fathoms. I also fish some spots in BC that are considerably shallower but very short drifts so there is a lot of reeling. I love them and would not be without.
There are drawbacks. There is a learning curve with these reels. They are extremely powerful and you can actually staighten hooks or even rip good hooksets right out of the fish. This can be avoided if the operator is cognizant of all the factors. Number one being of coarse the drag tension. If you are reeling at the same time a fish decides to run and the boat begins to rise with a swell, you had better have the drag right or something is going to give. The reels are not instant off when you release the button. There is a transmission in motion and so there is a little lag time. This also becomes an issue for rod tips. My 612 is fast so you had better be paying close attention when your terminal tackel is close to the rod or you will snap the pole at the tip. On recovery I like to loosen the drag tension so it is just tight enough to retrieve the gear with out sliping that way there is a little room for error.
The reduced recovery time translates to more time
fishing which means a great deal to me but I have found some fisherman just don't grasp the instructions on use!

As for the Wisenhut; I've used them also and do not care for them. There design allows you to use the reel both electric or manual. Meaning the handle stays in place. This can be a problem with finger pinching and also I've seen long hair get tangled in it! :shocked:
My recomendation would be Electra-mates or Precision Auto Reels.
Hope this helps.
