I agree, dipsy divers are a really good option for those starting out with trolling. I have very fond memories of fishing with my Dad over 20 years ago and the first time we tinkered with the dipsy divers. Started slow with just two on each side of the boat and still remember the thrill we both had when the the walleyes first tripped those divers with "Fish On". The anticipation and then the strike, nothing better.

I've posted a video on how to use dipsy divers at www.walleye.com . Scroll down half way on the main page and you'll see the video.
