  Air consumption 2cfm Approx. Max air pressure 90psi.  


The SL2 Pen is typically the pen of choice for working on more fragile or softer rocks such as chalk, oolites and fine laminates, smaller delicate fossils such as trilobites and for work under magnification where the power of the TT can become largely unused. The SL2 has a more refined power delivery for close fine work While still remaining a decepetively powerful pen for roughing out and general 'spade work'.

The TT pen is the more powerful of my two pens. It is typically the first choice of pen for those bigger pieces such as large ammonites and large nodules and mass assemblages when the user might benefit from faster matrix removal. It is noiser than the SL2 at full power but still remains capable of fine finishing work when turned down.

The SL2 Fossil Preparation Pen was designed and is manufactured solely by us specifically for Fossil Preparation

It has important and unique fossil preparing features developed on an extensive range of fossils over many years that we know benefit users, particularly those doing a lot of high end important work, who can take full advantage of the refinements

The SL2 pen has a complex alloy twin bearing design mounted within a high grade aluminium alloy body with stainless steel internals to support the very long stylus at critical points. Virtually erradicating any deflection at the tip , significantly increasing smoothness and drastically cutting down operating noise.

Extremely flexible and surprisingly robust, this pen has a top level combination of characteristics such as lightness smoothness and flexibility that is hard to match.

Proven reliability comprehensively supported by our total spares availibility and service backup

Features include

  • An essential focused Airstream over the tip to keep the point clear
  • Can operate over a wide pressure range. Just as happy at 45 psi as 90psi
  • Quiet and smooth running
  • Well balanced for fossil preparation
  • Instant lever switch adjustment through a wide range.
  • Simple to maintain, only three basic moving parts.
  • Inline filter, lubrication, sheath, spare seals included.
  • Simple variable hose length adjustment
