Hi everyone !
Both of the subject detectors are made by First Texas and except for a few cosmetic changes, look almost alike.
The difference in the msrp is $150.00, so I decided to compare specifications.
I copied specs. from the two websites and added a Legend with msrp prices at the bottom.
Bottom line, there are only two specifications that differ (Legend codes 1 and 2)
Hope this proves useful...........My gift to you.........Merry Christmas !

F75 Specifications copied from Fisher Website on 12-16-2010 by Todd Brock (aka: ToddB64).
F75 Specifications
S--Mechanical: S-rod with electronics housing mounted on handgrip, 3-piece breakdown,
batteries under elbow, 2-way armrest adjustment forward/backward & around forearm.
S--Searchcoil: 11 (28 cm) open-frame elliptical double-D, waterproof.
S--Batteries: 4 AA, alkaline (included).
S--Weight: 3.5 pounds (1.6 kg) with alkaline batteries installed.
S--Static Balance: force in vertical plane normal to elbow 0.47 pounds (0.22 kg).Varies with adjustment and users stance and arm/hand
physiology.
S--Dynamic Balance: axial moment, 0.29 foot-pounds (0.39 newton-meters). Varies with adjustment and users stance and arm/hand physiology.
S--Sweep Effort: lateral moment 5.2 foot-pounds (7.1 newton-meters).
S--Operating Principle: VLF induction balance
S--Operating Frequency: nominal 13 kHz, quartz crystal timing reference
1--Basic Sensitivity: 6 x 10 9 root Hertz (detectivity)
2--Lag Coefficient: 78 milliseconds
S--Reactive Overload: approximately 10,000 micro-cgs units (volume susceptibility)
40,000 micro-cgs units with sensitivity < 30.
S--Resistive Overload: approximately 1,200 micro-cgs units (volume susceptibility)
4,800 micro-cgs units with sensitivity < 30.
S--Ground Balancing Range: From ferrite to salt, inclusive
S--Discrimination Ground Suppression: combination of second and third order methods
S--ID Ground Suppression: third order
S--Battery Life: Typically 40 hours with high quality alkaline batteries
Estimated 80 hours with nickel oxyhydroxide batteries
Estimated 65 hours with lithium iron disulfide batteries
S--Operating Temp Range: 4 to +122 degrees F (-20 to +50 degrees C)
S--Operating Humidity Range: 0-90% non-condensing
Legend and Prices (Created and Added by Todd Brock (aka: ToddB64):
S = Same as Teknetics T2
1 = Teknetics T2 = ( 5 x 10 9 root Hertz ( detectivity ) = 5,000,000,000 = Five billion root hertz
2 = Teknetics T2 = ( 70 milliseconds )
Fisher F75......msrp = $1199.00 Teknetics T2......msrp = $1049.00
