ABOUT YOUR DETECTOR

Fisher Research Laboratory has been producing rugged, high

quality, high performance metal detectors since 1931, longer than

any other company in the world. Your IMPULSE is a product of

that proud heritage. Designed for deep-sea treasure hunting,

the IMPULSE will also do the job in surf, on the beach, in fresh

water or on land.

Pulse induction (PI) metal detectors have been around for years.

Their ability to detect metal in black sand and salt water make

pulse induction metal detectors particularly suited to underwater

treasure hunting, wreck diving, shallow-water treasure hunting

and beach combing.

However, pulse induction metal detectors have had their

drawbacks. Most have been heavy, expensive and unstable,

requiring the operator to retune frequently. Pulse induction metal

detectors also have had high battery drain, creating frustrating

power loss and added expense.

But worst of all, pulse induction metal detectors have been

plagued by slow response. Because the search coil is slow to

respond to a target, sensitivity and depth can be maximized only

at slow sweep speeds, forcing the operator to slow down,

thereby covering less ground. “Autotune” pulse induction

detectors do have a rapid response, but the search coil must

be in motion to detect a target.

In 1985, engineers at Fisher Research Laboratory began work

on a new pulse induction metal detector, one that would

combine extreme depth in salt water with high battery

performance, stability, low cost and fast target response.

Their answer is the IMPULSE—a no-motion detector that responds

instantly to targets and frees the operator to hunt fast, slow or

with no motion at all. In addition, battery life of the IMPULSE has

been greatly extended over previous pulse induction detectors.

In fact, battery life of the IMPULSE is better than most induction-

balance metal detectors. And stability is greatly improved. There’s

no need to retune the IMPULSE every few feet.
