The PG01 (1984-2004) was replaced by the PG01B in March 2004. Those who have updated say “Better Glass Shop” “Easier to use”. All surfaces work with the PG01B (users must number their surface per instructions).
The 78 minute audio CD and the instruction manual will have you understanding and using the PG01B in no time. Cool new fixtures like the fast angles, reversible Squaring Fence for regular and thin art glass and a quality ruler with both metric and inch scales make the PG01B a must have for art glass enthusiasts.
