The Fisher F75 and Garrett’s AT Pro are multi-purpose VLF metal detectors from two of the main names in the business. They are both excellent machines but which is best for you? Fisher with its rock solid reputation or Garrett’s totally submersible machine?

What's Better? Fisher F75 vs Garrett AT Pro

A Detailed Comparison of The Fisher F75 vs The Garrett AT Pro


The Garrett AT Pro runs on 15kHz and the Fisher 75 runs on 13 kHz. There’s not much in it, but the higher frequency is more likely to pick up smaller targets and gold.


The AT Pro’s display is clear with Garrett’s excellent target ID, battery level, sensitivity, depth indicators, iron audio, notch discrimination and pinpoint.

The F75 has a larger digital screen with an easy-to-see numerical target ID. It has only three buttons which are power, a settings knob, and a menu button. It’s easy to use but is more time consuming than the AT Pro that has everything on the display.

There’s backlighting on the F75 but not the AT Pro.

Ground Balance

Both machines have both manual and automatic ground balancing. Fisher’s model provides current mineralization stats which is a nice touch.

Target Identification and Discrimination

Digital Target ID is provided on both the AT Pro and the F75 between 0-99. The Pro has coins, custom or zero discrimination modes whereas the F75 has two all-metal modes and a discrimination mode.

Reviewers tend to say that the F75 has better discrimination capabilities than the AT Pro.

Iron Audio

Both the AT Pro and the F75 have iron audio so you can detect without referencing the screen.


The AT Pro is submersible up to ten feet making it perfect for deep, shallow and water’s edge detecting. Fisher’s F75 does not have a waterproof control box. This is one of the main differences between the two models.


The AT Pro has three-tone audio with Pro Audio modes and the F75 has five-tone audio.


The AT Pro has Garrrett’s 8.5 x 11 inch DD PROformance coil whereas the F75 has Fisher’s 11″ elliptical DD coil.

Fisher’s will cover slightly more ground in a single swing, but there’s not much to choose between them.

Length and Weight

The AT Pro starts at 43 inches and stretches up to 56 inches. It comes apart into three sections to make transporting it easier and weighs 3.03lbs

The F75 measures from 43.5” to 52.5” and weighs approximately 3lbs.


The cost is comparable, but you might pay a little more for the AT Pro.

The Best Choice

The main difference between these two great VLF machines is that the AT Pro is submersible and the F75 is not. However, the Fisher F75 gives current ground mineralization readouts and has a scroll through display.

There’s not much to choose between the two here – but if you plan to detect around water I’d recommend the waterproof Garrett AT Pro to be on the safe side.
