GSA 10.8 V-LI
It is replaced by the GSA 12V-14 recipro saw.
The GSA 10.8 V-LI is a cordless handheld circular saw manufactured by Bosch as part of the Bosch Professional product line.
This product is marked as discontinued because in 2017 it was renamed to GSA 12V-14 when the 10.8 volt battery system was rebranded to "12V max".
The page of the renamed product contains more information.
