Your Personal Private Eye for U/W Metal Detecting

WHITE'S SURFMASTER P. I. DEEP DIVER

by Tamara Collins



Gold rings sometimes slip off wet, cold fingers. Necklaces can come unclasped when people lose their inhibitions and frolic in the waves. Clothes, discarded in heaps on the beach, contain coins that can easily spill into the sand. Some may view combing the beaches for this booty a predatory sport but, hey, someone needs to liberate it from its tomb of sand; and it might as well be you.
You will want the tool for your hunt to be highly effective and lightweight because, despite the pleasure detectorists get from their hobby, it can be gruelling work. Slow sweep speeds and heavy machinery can make it a tedious, backbreaking process. Fortunately, a Surfmaster P.I. Deep Diver may make sleuthing a little easier.

P.I. doesn't stand for private investigator (although it has a nice ring to it) but is actually an acronym for pulse induction; the operating system that allows the Surfmaster to detect metal in mineralized ground and salt water, which are conductive and can give a false reading to induction balance (VLF; very low frequency) metal detectors. VLF does have its advantages, though; a fast sweep speed, high sensitivity, stability and ease of use; and White's Electronics set out to include these in the design of its pulse induction metal detector.

When I took the Surfmaster from its box, my initial impression was of its well balanced, lightweight configuration. Constructed of aluminum Lexan, graphite and electronic components, it is only four pounds, eight ounces (virtually neutral in salt water) with the nine and a half inch weighted loop, making it one of the lightest metal detectors SKIN DIVER has featured in the past year. It is also available with a lightweight beach loop or Deep Diver set, each a few ounces lighter than the weighted loop. When I began to investigate further into the Surfmaster's features and benefits, I found much more to impress me.

More than 10 years' research and development resulted in the Surfmaster P.I. Its fast target response allows an optimum sweep speed of three to five feet per second and its fully automatic tuning (SAT; self-adjusting threshold) gives it a high degree of stability and sensitivity. And, with rare coins, medals and gold and silver jewelery being the lure of most detectorists, it was designed to be more sensitive to gold and copper-nickel alloys than to other metals. The user can also tune out some types of non-ferrous trash, such as aluminum foil, with the pulse delay control, which also turns the Surfmaster on and off. This knob is next to the tuner control on the top side of the control box. The tuner lets the operator adjust the speed of the background rhythm or threshold. The tuner is also used to test the condition of the battery pack.

The Deep Diver utilizes a unique vibrator rhythm that is easier to hear underwater. When the loop passes over a metal target, the rhythm speeds up. The center of the loop is the most sensitive area. If the loop is held still over a target, the SAT system will tune out its transmission and return the detector to threshold level. Therefore, the Surfmaster must be kept in constant motion.

The signal is heard through a pair of adjustable, waterproof headphones. The headphones are connected to the O-ring sealed control box, which is conveniently placed on the diver rod between the cushioned arm cup and handle. The control box is the brain and powerhouse of the Surfmaster. It contains eight AA penlight batteries. Alkaline batteries are recommended and should provide 25 to 35 hours of continuous operation.

Think of the booty scattered by people that have come in droves to oceans and lakes throughout the years. Or, imagine the shipwrecks awaiting exploration, with brass fittings and copper portholes buried under layers of sand. Whatever the focus of your search, you will need the assistance of a metal detector. Surfmaster P.I. Deep Diver will take you from dry land, to the water's edge and into the water to 100 feet. It requires a small investment of $00 and, if you're diligent, you could make that back in a short time.
