Lost Treasure Magazine has a nice review and field test of the Garrett Sea Hunter Mark II. They start off by reviewing the features of the metal detector then move onto the field test, which is some general reading and doesn't provide much in the way of tips on the Sea Hunter Mark II. They conclude with a recommendation of the metal detector saying "The Mark II comes complete with everything you need to configure the detector for beach hunting, wading or diving without the need to purchase any additional components" and offering a tip on the assembly.
