Different size coils have different detection ranges. Large coils have very wide and deep detection envelopes for finding larger objects at deeper depths. Small coils have small, but very concentrated, detection envelopes which more easily locate smaller targets.

In order to install any of the optional coils on you Pulse 6X or 8X detector, it is necessary to have the optional "underwater connector on coil wire". This option allows the standard search coil to be detached form the electronics housing and optional coils to be attached. This option can be installed on any new detector or older Pulse 6X and Pulse 8X models. Call for more information.

Underwater Connector:
 The "underwater connector on coil wire" option allows the standard 7.5" coil to be detached from the detector's electronics housing so any of the optional coils can be attached. The optional coils greatly increase the 

versatility and enhance the capabilities of these detectors. For instance, there are two coils designed for boat deployment. Sit in the boat with the detector's electronics unit, put the coil with its 100 foot cable over the side, and you can search for anchors, cannons, outboard motors, etc. Attach the 16" coil with its short diver handle and you can cover an area quickly when searching for those larger targets.

One detector with a few different coils can do the work of two or three different detectors. The Pulse 6X and 8X can be used on land, dive to 200 foot depths, or deployed from a boat.

8" x 48" Oval coil with skids and 100' cable:
The 8 by 48 inch coil has the largest detection area of all the optional coils. For a large target, such as several cannons or a ship's boiler, the detection envelope extends four feet to either side of the coil (12 foot total width) and 8 feet below the coil. The coil is mounted on four small skis for dragging along the beach or in shallow water. This coil is ideally suited for locating buried targets because it travels just inches away from the bottom. The unique oval design gives this coil both good sensitivity to small targets (rings, coins, etc.) and deep detection of larger targets. The 8 by 48 coil has been used by treasure hunters worldwide for locating coins and jewelry along beaches as well as gold and silver bars at wreck sites. The P6/8X must be ordered with the optional u/w connector to use this coil.

Price: $995.00

16" Coil:
The 16 inch coil is the largest coil that can be attached to a handle. The 16" coil has a detection envelope that extends more than three feet to either side of the coil and seven feet below the coil. This coil has excellent sensitivity to larger targets and is ideal for locating cannons, gold bars, anchors, pipelines and outboard motors. The 16 inch coil is in use by commercial diving companies worldwide for locating and track pipelines. The P6/8X must be ordered with the optional u/w connector to use this coil.

Price: $295.00

18" Coil with 100' cable:
The 18 inch coil with 100 foot cable is designed for boat deployment. The coil is lowered to the bottom, raised a few feet above the bottom, and trolled along at slow speed. The detection envelope extends 5 feet to either side of the coil and seven feet below it. This coil is ideally suited for covering small search areas when looking for outboard motors, anchors, cannons and other large targets laying on the river, lake or ocean floor. The 18" coil its 100 foot cable is in use by numerous law enforcement agencies for weapons recovery operations and to locate vehicles dumped into rivers and quarries. The P6/8X must be ordered with the optional u/w connector to use this coil.

5" Coil:

Price: $165.00

10" Coil:
The 10 inch coil has a detection envelope that extends to almost three feet on either side of the coil and six feet below the coil. This coil's detection envelope is slightly larger than the standard 7.5 inch coil which comes on all Pulse 6X and 8X detectors. The larger detection pattern allows an area to be searched more quickly with fewer sweeps of the coil. The 10 inch coil will detect larger targets at slightly deeper depths than the 7.5 inch coil but, is not quite as sensitive to the smaller targets such as rings and other jewelry items. The P6/8X must be ordered with the optional u/w connector to use this coil.

22" Hand probe with 1" coil:
 The 22 inch hand probe has a 1 inch coil molded into the end of the probe. This coil has a small but very concentrated detection envelope that extends several inches around the probe tip. The probe is ideally suited for detecting targets lodged between rocks or crevices in reefs. The probe also works well for detecting pockets of coins on wreck sites where larger coils may react to the many large metal objects surrounding the coins. The probe can also be inserted into soft muddy bottoms to pinpoint targets. The P6/8X must be ordered with the optional u/w connector to use this coil.

Carry Bag:
This rugged cordura nylon bag is specially designed to hold your Fisher Pulse 6X or 8X detector and all its accessories. The bag is included with the purchase of every Pulse 8X and is an option for the 6X

Price: $50.00

Extra Battery:
An extra 9 volt NiCad battery pack can be field installed in your 6X or 8X detector at any time. Unlike many other underwater detectors on the market today, Fishers detectors can be disassembled without damage to the detector or voiding the warranty. An extra battery pack will allow you to operate the detector virtually around the clock if necessary. With a spare battery pack your detector will always be ready to go.

Price: $75.00

220 Vac Charger (Europe):
 If you are in a country where 220 is the standard voltage, you can charge the 6X and 8X detectors with this 220 volt charger. The 220 volt charger attaches to the standard 120 volt charger included with each detector to allow charging from a 220 volt outlet.

Price: $35.00

Dual Underwater Headset:
A single underwater earphone is included with every Pulse 6X and 8X detector. The single underwater earphone slips under the mask strap or into the diver's hood. If you prefer, this dual headset is available for underwater use that provides a separate earphone for each ear with a connecting headband. The dual underwater headset is much louder than the single earphone.
