You might as well buy electrics now cuz you will eventually want them. I had manuals, but one day salmon fishing we must have reeled them up a good 50 times after landing 38+ salmon in 4 hours. The next morning my arm was immoble. LOL. Think of how nice they will be when you get your limits of Sockeye next year on Washington
One thing you must think of is the speed in which you can get your downrigger cables out of the way of the fish you are fighting. If you hook a fat fish and can't get the downriggers reeled in before the fish darts under or around your boat, you'll probably not even get to see the fish, and you'll kick your own azz for not getting the eletrics. It's hard to fight a big fish with one hand on the crank and one on your pole. I know this first hand
. With the electrics you just hook the fish and turn the dial and forget it.
Scotty brand reels in 3ft per second with the lowest amperage drain of any model on the market. All models have the same motor, from the base model to the highest priced PRO version. So my advice is to go with the 24" model(lowest priced). 24" is the boom or arm length, you can always extend the boom in the future if you need to. It lists for $269 at Sportco in Fife. I bought 2 and run them off one battery and they have worked nicely with no problems. And they have got me more fatties than i ever thought i would catch.
