The short answer

The Minelab Excalibur II with the 10-inch hardwired coil is worth buying when your actual plan includes scuba, deep wading, surf or repeated saltwater work. Minelab rates it to 60 meters (200 feet), far beyond ordinary wading detectors.

It is the wrong buy for someone who mainly hunts parks, fields or dry beach. The current model weighs 5.1 pounds, has no screen or numeric target ID, and hardwires both the search coil and headphones. Those compromises make sense underwater; on land they are simply compromises.

What the Excalibur II actually is

The current U.S. model is SKU 3303-0124. It uses Minelab’s BBS multi-frequency system, a 10-inch Double-D coil, Koss waterproof headphones, rotary controls and a rechargeable NiMH battery pack. The standard shaft covers upright beach and surf use, while the included shorter dive shaft reduces the detector’s length underwater.

This is not a modern all-terrain detector placed in a waterproof shell. It is a purpose-built analogue-audio dive machine. The product decision therefore starts with depth and hunting environment, not with feature count.

Key specifications that change the decision

Specification Current Excalibur II Why it matters
Waterproof rating 60 m / 200 ft, IP68 Suitable for serious diving, not merely rain and wading
Operating system BBS simultaneous multi-frequency Designed to remain usable in conductive saltwater conditions
Standard coil 10-inch round Double-D, hardwired No quick coil swap; fewer underwater connection points
Headphones Hardwired waterproof Koss headphones Reliable for diving, but no casual headphone choice
Target information Continuous multi-tone audio; no display or numeric ID Buyers must interpret sound rather than read a target number
Search modes Discriminate and All Metal Focused control set rather than a menu of land programs
Weight 5.1 lb / 2.3 kg with 10-inch coil and battery Heavy for extended land swinging
Battery Rechargeable NiMH; 14–19 hours published runtime Adequate for long sessions, but an older battery format
Warranty 12 months on control box and coil Shorter than many current premium land detectors

Buy it for these three jobs

1. Scuba and deeper submerged hunting

The 200-foot rating is the reason to buy this detector. Many current waterproof machines stop at 10 or 16 feet. If the target site is below that range, comparing screens and wireless headphones misses the decision entirely.

The hardwired coil and headphones also make more sense here. A fixed connection removes the temptation to treat a deep-water machine like a modular land detector. The downside is repair and replacement complexity if a cable is damaged.

2. Surf and saltwater work where audio is acceptable

BBS transmits multiple frequencies simultaneously, and the Excalibur II is designed around difficult salt and mineral conditions. It offers Discriminate and All Metal modes, automatic ground rejection and continuous multi-tone target audio.

That last point is a hard gate. If you rely on a screen or numeric ID to make dig decisions, this is the wrong control language. The Excalibur rewards a buyer prepared to learn threshold and tone changes.

3. A dedicated second detector

The Excalibur II makes more sense as a specialist beside a lighter land detector than as the only machine in a mixed hunting kit. Its dive shaft, high-visibility body and sealed audio system solve a narrow job well. They do not make ordinary turf hunting more pleasant.

Skip it in these situations

  • Most hunts are on land. A 5.1-pound, audio-only dive detector is unnecessary when a lighter screen-equipped machine covers the site.
  • You want interchangeable coils and headphones. Both are hardwired on the Excalibur II.
  • You want a modern rechargeable ecosystem. The supplied battery is a 12-volt NiMH pack rather than the internal lithium system common on newer detectors.
  • You want numeric target confirmation. There is no target-ID display or depth meter.
  • You need a long premium warranty. Minelab publishes a 12-month warranty for the control box and coil.

For beaches, parks and fields with water no deeper than 5 meters, a lighter machine such as the Equinox 900 is easier to justify. Choose the Excalibur only when its much deeper rating changes where you can hunt.

New versus used: the condition gate

Waterproof gear can fail at the places a listing photo hides. A used price is not attractive until the seller proves that the sealed system has been cared for.

Inspection point Pass signal Walk-away signal
Coil and headphone cables Flexible, clean, no splits or sharp bends Cracks, stiffness, taped sections or stress at entry points
Battery pod and cap Clean threads and intact sealing surfaces Salt deposits, cross-threading, corrosion or improvised seals
Controls Smooth, intact knobs with clear response Loose shafts, damaged markings or erratic operation
Charger and battery Correct charger and a battery that holds a usable cycle Missing charger, heat damage or unknown substitute pack
Shaft and mounts Complete standard and dive hardware Missing clamps, stripped fasteners or nonstandard repairs

Ask for a dry functional demonstration and evidence that the unit was rinsed after saltwater use. Do not accept a seller’s claim that a machine is waterproof as proof that an aged seal or cable remains sound.

Ownership after saltwater use

Minelab warns that salt, sand and grit accumulate on the Excalibur II. Fresh-water rinsing, careful cable handling and clean sealing surfaces are part of ownership. Do not wrap hardwired cables into tight bends or use the coil cable as a carrying handle.

Battery planning matters too. Minelab publishes 14–19 hours from the rechargeable NiMH pack, but an older used pack may deliver less. Budget for the actual state of the battery, not the runtime it achieved when new.

The best alternative depends on depth

Your real use Better fit
Scuba or submerged hunting beyond 16 feet Excalibur II
Surf, wading, beaches, parks and fields Equinox 900 or another lighter 5-meter all-terrain detector
Very occasional shallow water A land-first detector with an appropriate waterproof rating
Audio-only specialist who wants fixed underwater hardware Excalibur II
Buyer who wants screens, presets and wireless land audio Newer all-terrain detector

The Excalibur’s value rises sharply when the 200-foot rating is required and falls sharply when it is not. That is a cleaner decision than treating it as a prestige upgrade.

Verdict

Buy the Minelab Excalibur II for dedicated diving, surf and saltwater hunting where 60-meter waterproofing and hardwired underwater audio solve a real problem. The current 10-inch model is a specialist tool with a clear job.

Skip it for general land use. Its weight, audio-only target information, fixed coil and headphones, NiMH power system and one-year warranty are difficult to justify when the hunt never approaches its depth advantage.

Frequently asked questions

How deep can the Minelab Excalibur II go underwater?

Minelab rates the current Excalibur II to 60 meters or 200 feet. Its 10-inch coil and Koss headphones are hardwired as part of that dedicated dive design.

Does the Excalibur II show a numeric target ID?

No. It has no display or numeric target ID. The detector uses continuous multi-tone audio, rotary controls and variable discrimination, so the buyer must be comfortable making dig decisions by sound.

Is the Excalibur II a good first detector?

Only for a buyer whose first priority is diving or sustained saltwater hunting. At 5.1 pounds with hardwired audio and no screen, it is a poor general-purpose first detector for parks and fields.

What should you inspect on a used Excalibur II?

Inspect the hardwired coil and headphone cables, cable entry points, battery pod, seals, charger, controls and shaft hardware. Salt residue, cracking, stiffness or improvised repairs are reasons to walk away.
