Fisher F75 LTD Metal Detector with Boost and Cache Modes

The Fisher F75 LTD is a high-performance 13 kHz VLF metal detector built for relic hunting, coin shooting, and gold prospecting in mineralized and trashy ground. The LTD adds Boost Process for extra depth and Cache Locating Process for large deep targets to the proven F75 platform, and it ships with both an 11-inch DD and a 5-inch DD waterproof coil, so you are ready for open fields and tight, trashy sites without buying extra coils. FASTGRAB ground balance, a 0 to 99 numeric target ID, adjustable FeTone iron audio, and DST digital shielding keep it fast, deep, and stable where lesser machines chatter. It is one of the most capable relic and treasure detectors in its class.

What's included

• Fisher F75 LTD detector with control housing and S-rod shaft
• 11-inch DD waterproof search coil
• 5-inch DD waterproof search coil
• Four AA alkaline batteries
• Operating manual and two-year Fisher warranty

Why detectorists choose the F75 LTD

• Boost and Cache modes. Boost Process adds depth in most soils, and Cache Locating Process reaches large deep targets, so the LTD doubles as a deep relic and cache machine.
• DST digital shielding. Suppresses electromagnetic interference from power lines and cell towers, so you can hold sensitivity on urban sites where other detectors force you to turn it down.
• Fast target separation. Double-filter discrimination and a fast processing mode pull keepers from between nails in iron-choked ground.
• Dual DD coils in the box. The 11-inch DD covers open ground and the 5-inch DD works tight, trashy spots and small gold, no extra purchase.
• Fast, trigger-driven controls. Trigger-actuated FASTGRAB ground balance and pinpoint mean no menu diving mid-hunt. Light and well balanced for all-day swinging.

Where the F75 LTD performs best

Relic hunting in iron-infested sites

Double-filter discrimination and FeTone iron audio (Off, Low, Medium, High) give you granular iron control in trashy Civil War camps, colonial homesteads, and old fairgrounds. Fast separation lets you work between nails, and DST keeps the machine quiet near power lines. Many hunters identify wrought iron from brass by audio pitch alone before digging.

Coin shooting in parks and lawns

The 0 to 99 numeric target ID and adjustable audio pitch let you cherry-pick high conductors in trashy parks without digging every tab. The 11-inch DD covers ground fast, and trigger pinpoint narrows the target before you cut a plug. Compare it against other machines on our best metal detectors for coins page.

Gold prospecting in hot soil

The ground-balance range spans ferrite to salt, and manual ground cancellation fine-tunes black sand and ironstone. The included 5-inch DD coil is sized for working between rocks in dry washes and hitting small nuggets. The 13 kHz frequency is a proven gold frequency, and Boost mode holds a stable threshold in mineralization. See more gold prospecting detectors.
