Description
The EQUINOX 600 and 800 have been digging since 2018, and the lower shaft is the part that carries every one of those miles: the yoke ears fatigue, the camlock face scuffs, the tube takes the hit when the detector rides in a trunk. Minelab still makes the genuine lower, and it is also the cheapest way to make coil changes take seconds.
At a glance
Genuine Minelab EQUINOX 600/800 lower shaft, part 3011-0401, UPC 811493017129. Minelab's own listing: A replacement or backup for the lower shaft of your EQUINOX 600/800 metal detector. Sold by History Seekers Metal Detectors, an authorized Minelab dealer; same-brand fitment, Minelab's own description, nothing invented.
Why this part
Minelab describes this part as a replacement or backup for the EQUINOX 600/800 lower shaft, and both halves of that sentence are the argument. As a replacement, it restores the factory camlock fit a worn lower loses, the fit that keeps the coil from wobbling in wet sand. As a backup, it is the multi-coil trick every EQUINOX owner eventually adopts: one lower shaft per coil, each pre-mounted with its own bolt and washers, so swapping the EQX 06 for the EQX 11 or the EQX 15 is one camlock and no hardware. The coil bolt stays torqued instead of being worked loose every hunt, which is how coils stop rattling.
Which Minelab machine is this for?
| Machine or coil | Fits? | Note |
|---|---|---|
| Minelab EQUINOX 600 and EQUINOX 800 | Yes, listed by Minelab | The original 600/800 shaft system. |
| Minelab EQUINOX 700 and EQUINOX 900 | No | The 700/900 run a different shaft; their middle shaft assembly is listed separately. |
| Coils | EQX 06, 11 and 15 | EQX 06, EQX 11 and EQX 15 all mount to this lower with the standard coil bolt. |
Specs and what they mean in the field
| Spec | Value (Minelab) | What it does for you |
|---|---|---|
| Position | Lower shaft, coil end, with yoke | The section the coil bolts to and the camlock grips. |
| Fit | EQUINOX 600 and 800 (Minelab) | Not the 700/900 shaft system. |
| Why a second one | One lower per coil | Coil changes become a camlock swap; bolts stay torqued. |
| Part | 3011-0401, UPC 811493017129 | Genuine Minelab; the camlock diameter and yoke spacing match. |
Fitting it and keeping it working
Set the lower in the camlock at the length you actually hunt at and mark it with a wrap of tape, so every reassembly lands at the same length and the same balance. Rinse the camlock after salt water and let it dry open; sand inside the lock is what makes a good lower feel worn.
Frequently Asked Questions
Does this fit the Equinox 700 or 900?
No. Minelab lists this lower shaft for the EQUINOX 600 and 800. The 700 and 900 use a different shaft system; their middle shaft assembly is listed separately.
Will my coil hardware fit it?
Yes. The standard EQUINOX coil bolt and washers mount any EQX 06, EQX 11 or EQX 15 coil to this lower, so each coil can live pre-mounted on its own shaft.
When should a lower shaft be replaced?
When the camlock no longer holds with the lever fully closed, when the yoke ears are cracked or spread, or after travel damage. A loose lower shows up as a coil that wobbles in wet sand.
Why do people run more than one lower shaft?
So a coil change is a camlock swap instead of a hardware session. One lower per coil, pre-mounted, means the coil bolts stay torqued and the swap takes seconds in the field.
