Fitting Coiltek Extreme Coils to the Minelab SDC 2300 detector + Warranty
The Minelab SDC 2300 detector was released in 2014, and it is still in production nearly a decade later in 2023. Minelab have only ever offered the 8” round monoloop coil on this pulse-induction detector. Minelab states that the SDC 2300 detector (including the Minelab 8" coil) is "Fully submersible to 10’ (3m) for detecting riverbeds and shorelines, allowing you to transition with ease from land to water."
In recent years, Minelab have offered an "upgraded" SDC 2300 which includes a Lithium-ion battery (it can also operate on 4 C-cell batteries too), and a coil joint ("knuckle") protector.
In 2020, Australian company COILTEK released a range of three larger/different sized monoloop coils – named the ‘Gold Extreme’ - for the SDC 2300 detector.
These three coils are the elliptical 14x9”, the elliptical 10x5”, and the 11’ round – priced from about $400.
It should be noted that the Coiltek Extreme coils are Water Resistant, NOT WATERPROOF !
In September 2020 Minelab issued an updated Product Notice & Warranty Statement regarding the fitment of Coiltek coils to the Minelab SDC 2300 detector. This advice from Minelab states:
“SDC’s with Coiltek aftermarket coils fitted by the user REMAIN WARRANTED by Minelab. That is, SDCs that may be experiencing issues can be repaired (under warranty if applicable) via the normal Minelab sales and support channels in your region.
If the issue is related to failure of the Coiltek Coil itself, then this is covered by Coiltek separately. Any damage which is assessed by Minelab or its Authorised Service Centres (ASC's) as having resulted from such modification will not be covered by the Minelab warranty. SDC’s should be reinstated to the original format (i.e. with original coil fitted) prior to returning to Minelab.
The aftermarket coils have been developed independently of Minelab therefore Minelab cannot provide any information or support regarding the use or performance of these coils. SDC’s with Coiltek coils experiencing issues related to the coil should contact Coiltek support.”
Fitment of a Coiltek coil also requires the use of a Coiltek Gold Extreme SDC Accessory Pack (costing approx. $90).
The Coiltek coils are simple to fit to the SDC 2300 – taking only several minutes to do so – as per this Coiltek instructional video.
The Coiltek Gold Extreme coils have a 2-Years Coiltek Warranty from the original date of purchase.
