Military & Presentation Compasses

Pyser-SGI offers a full service and alignment facility for all models we produce. They are serviced and repaired by our technicians to a very high standard, using only in-house manufactured parts.

Once completed these are then put through our environmental test chamber and a full calibration is carried out in our sighting room. Our compasses are calibrated to the three hemispheres, North, South and Equatorial. All compasses produced are calibrated to Admiralty traceable standards.

Military stabilising Binoculars & Spotting Scopes

Our technicians have many years’ experience, with servicing binoculars and spotting scopes. We offer a full repair, refurbishment and optical realignment to all our models sold. After each repair these are thoroughly tested to meet our exacting standards. They are then purged with dry Nitrogen for water proofing and sealing.

We also service and repair the Fujinon Gyro-stabilised day and day/night binocular as well as the Techno Stabi TS1440. Again we offer full refurbishment and optical realignment. Where necessary, we can set up the gyro assemblies electronically and we hold spare parts for all models.
