    The Nokta Middle Shaft (Carbon Fiber), part 17000650, is the standard-length carbon fiber middle section for the Nokta Simplex LITE, Simplex ULTRA, the original Legend, Score, Double Score, Triple Score, FINDX and FINDX Pro. It sits between the armrest and control box assembly and the lower shaft. Use it to replace a cracked or bent middle shaft, or to swap the stock middle shaft for carbon fiber on models that do not ship with one.

    Who the Nokta carbon fiber middle shaft is for

    • Owners replacing a damaged middle shaft: this is the genuine Nokta part for these detectors, so it goes in at the same length as the original section.
    • Simplex LITE, FINDX and FINDX Pro owners who want carbon fiber: Nokta lists the stock shaft on the Nokta Simplex LITE, Nokta FINDX and Nokta FINDX Pro as aluminum and plastic. Pair this middle shaft with Nokta's carbon fiber lower shaft, part 17000067, to run carbon fiber from the armrest to the coil.
    • Nokta Score owners: Nokta specifies carbon fiber on the lower shaft only for the Nokta Score, so this middle shaft gives the Score a full carbon fiber shaft.
    • Simplex ULTRA owners: the Nokta Simplex ULTRA already ships with a fully carbon fiber shaft, so for the ULTRA this is a like-for-like replacement, not a weight upgrade.

    Look elsewhere if: you are tall and the detector is too short at full extension. Nokta's Longer Middle Shaft (Carbon Fiber), part 17000653, fits the same detectors and adds length. Owners of the Nokta Legend 2 need that detector's own carbon fiber middle shaft, part 17000572.

    Key features

    • Carbon fiber tube: carbon fiber does not rust, which matters if you hunt beaches, wet sand or damp ground and do not want corrosion at the joints.
    • Standard length: it matches the original middle shaft, so your detector keeps the same adjustable length range Nokta specifies for it.
    • Same shaft lock connection: the lower shaft slides in and locks the same way it does on the original part, so your lower shaft and coil carry over.
    • Genuine Nokta part: made by Nokta for its own detectors, not an aftermarket adapter.

    What is in the box

    • One Nokta Middle Shaft (Carbon Fiber), part 17000650

    The lower shaft, armrest and search coil are not included. You move your existing ones over.

    Compatibility

    Fits, per Nokta:

    Not on Nokta's list: the discontinued Simplex BT. Nokta no longer lists the BT for this part, so contact us before ordering it for a BT.

    Does not fit: the Nokta Legend 2, which uses part 17000572, or the older Simplex+. The Nokta Gold Kruzer and Kruzer use their own aluminum middle shaft, part 17000637.

    Standard or longer middle shaft?

    Choose this standard 17000650 middle shaft if the stock length already suits you and you only need a replacement or a carbon fiber swap. Choose the Longer Middle Shaft (Carbon Fiber), part 17000653, if you run your detector at full extension and still stoop. For the most length, Nokta also makes a Longer Lower Shaft (Carbon Fiber), part 17000652, for the same detectors.

    Installing the carbon fiber middle shaft

    Open the shaft lock and slide out the lower shaft. Remove the original middle shaft from the armrest and control box assembly, fit the carbon fiber middle shaft in its place, and slide the lower shaft back in. Re-wrap the coil cable along the shaft, then set your length with the lower shaft lock.

    Other genuine parts for these detectors are in our Nokta collection and our metal detector parts and accessories collection.

    Should I get the standard or the longer Nokta carbon fiber middle shaft?

    Get the standard Nokta 17000650 carbon fiber middle shaft if your detector already fits you and you only need a replacement, and the longer 17000653 middle shaft if you still have to stoop with the detector at full extension. Both fit the same Simplex LITE, Simplex ULTRA, original Legend, Score series and FINDX detectors. Both shafts and the matching lower shafts are in our metal detector parts and accessories collection.

    Answered by Dan P. · October 2026

    Will the carbon fiber middle shaft make my Simplex LITE lighter?

    Yes, on the Nokta Simplex LITE this middle shaft replaces a stock shaft that Nokta lists as aluminum and plastic, so it is a carbon fiber upgrade. The same applies to the FINDX and FINDX Pro. On the Simplex ULTRA it is a like-for-like swap, because the ULTRA already ships with a fully carbon fiber shaft. Coils and other parts for the LITE are in our Nokta Simplex LITE collection.

    Answered by John W. · October 2026

    Does the Nokta carbon fiber middle shaft fit the Simplex BT or Simplex+?

    Nokta does not list the 17000650 carbon fiber middle shaft for the discontinued Simplex BT or the older Simplex+, so we can't confirm a fit for either. Nokta lists it for the Simplex LITE and Simplex ULTRA, which replaced those models. If you own a BT, contact us before ordering. Current Simplex detectors and parts are in our Nokta Simplex ULTRA collection.
