If you are not trained in the proper use of an e-collar, please educate yourself before attempting to use correction with an e-collar. E-collars are great tools but are only training devices used to enforce known commands and give corrections. They can ruin a dog and take the drive and retrieve desire out of dog if not used correctly.
You may consider getting some DVD's and books on the subject. I will recommend "Retriever Basics with Danny Farmer and Judy Aycock" You can get this from Gun Dog Supply online for just a few bucks. There are many others. Read and watch as many as you can.

You cannot go wrong with Tri-Tronics collars, Dogtra are good also. The Tri-Tronics Sport is the cheap model and will do what you need once you have the experience if you don't allready...
Good luck! PM me any time if you need info.
