Many of our production products have gone through design upgrades or are available
in versions that may be upgraded to levels of increased refinement . Hence the MKII
or MKIII designations. Upgrades are not limited to current models. Virtually any
Blue Circle product, no matter what its vintage, can be upgraded to reflect the current
state of the art - or beyond. We don’t believe in planned obsolescence.
These are some examples of upgrades offered for out-of-production models. If you own an older Blue Circle product and are interested in a possible upgradecontact us for details.
