(Compatible with the Fisher F-75 Metal Detector)  

Sun Ray Detector Electronics is proud to announce our new Invader™ series of aftermarket accessories for Fisher metal detectors! The new Sun Ray Invader FX-1 Target Probe has been developed to satisfy the pinpointing and retrieval needs of Fisher F-75 owners. We have received many requests for an in-line target probe for the F-75.  Now F-75 owners can enjoy the same benefits our quality Sun Ray in-line probes have offered users of previous Fisher models!  Here are some of the features of the FX-1:

Fully compatible with the Fisher F-75 model only.  The FX-1 is precision built to ensure peak performance.

Accurate "bulls eye" pinpointing on coin size targets up to 3" + deep depending on settings, operation modes,  ground and moisture conditions!

New compact, light weight, waterproof/submersible 6" X 1" diameter probe mounts nicely along arm rest for easy access. FX-1 probe and cable weigh approx. 5 oz. FX-1 switch box, connectors, cable and two probe clips, etc. weigh approx. 5oz. - approx. 10 oz total!

While the FX-1 probe is waterproof the switch box is water resistant and must not be submersed.

Installation requires no tools or modifications to the detector. Switch box and probe clips are attached by removable velcro lined clips.

The FX-1 incorporates all of the same functions as the stock coil including visual and audible target ID along with identical pinpoint functions! 

High quality custom made, durable probe and connector cable used for precision performance. Probe incorporates a 30" straight cable with strain relief for "tangle free" operation.

Quality high performance toggle switch used for peak performance! (Minimum 100,000 mechanical life operation-as described in manufacturer's specs) 

Toggle switch shuts off coil as it turns probe on and vise versa. Coil and probe are never on at the same time.

FX-1 switch box is conveniently mounted  on detector pole in a neutral position (for both right and left hand users) and to prevent toggle from being accidentally switched or bumped by user or damaged by tree limbs, brush, etc. if switch box is brushed or hit during detecting.

No external buzzers, vibrators or lights are needed as all target responses are heard clearly through your detector headphones!

No extra batteries required as the FX-1 utilizes the detectors power source.

Complete installation & operation instructions included. 


No more Empty holes! No more scratched or damaged targets!

Experience a Sun Ray in-line probe on your detector and you'll wonder how you ever got along without it!!
