Treasure Hunting

A recent review of the Fisher F-75 metal detector on metaldetectorreviews.net says it’s one of the best, and the sites’ readers give it a rating of 3.5 stars (out of 5).

Specs:

• Mechanical: S-rod with electronics housing mounted on handgrip, 3-piece breakdown, batteries under elbow, 2-way armrest adjustment forward/backward & around forearm.
• Searchcoil:11” (28 cm) open-frame elliptical double-D, waterproof.
• Batteries: 4 AA, alkaline (included).
• Weight:3.5 pounds (1.6 kg) with alkaline batteries installed.
• Static Balance:Force in vertical plane normal to elbow 0.47 pounds (0.22 kg).Varies with adjustment and user’s stance and arm/hand physiology.
• Dynamic Balance:Axial moment, 0.29 foot-pounds (0.39 newton-meters). Varies with adjustment and user’s stance and arm/hand physiology.
• Sweep Effort:Lateral moment 5.2 foot-pounds (7.1 newton-meters).
• Operating Principle:VLF induction balance
• Operating Frequency:Nominal 13 kHz, quartz crystal timing reference
• Basic Sensitivity:6 x 109 root Hertz (detectivity)
• Lag Coefficient:78 milliseconds
• Reactive Overload:Approximately 10,000 micro-cgs units (volume susceptibility) 40,000 micro-cgs units with sensitivity
• Resistive Overload:Approximately 1,200 micro-cgs units (volume susceptibility) 4,800 micro-cgs units with sensitivity
• Ground Balancing Range::From ferrite to salt, inclusive
• Discrimination Ground Suppression:Combination of second and third order methods allowing the F75 to opperate smoothly on different types of soil.
• ID Ground Suppression:Third order
• Battery Life:Typically 30 hours with high quality alkalines, somewhat less with rechargeables.
• Operating Temp Range:4 to +122 degrees F (-20 to +50 degrees C)
• Operating Humidity Range:0-90% non-condensing

We haven’t had a chance to play with this detector yet, so we can’t give an opinion, but with reviewers saying things like, “This machine has it all,” “F75, not your father’s detector,” and, “Deepest Detector out There,” we’re guessing it’s pretty good.

You can buy the Fisher F-75 at Kellyco Metal Detector Super Store for $934.15. If you do buy one, or already have one, let us know how you like it in the comments section.
