−	Window sample and windowless sample boreholes can be a quick and economical method for obtaining soil samples, which are recovered by inserting tubes of varying lengths into the ground. They are generally restricted to shallow depths but are suited to sites with limited access, sloping sites, and where minimal disturbance is required. This is a particular advantage with window sampling which uses tubes with longitudinal openings cut into them and are inserted using either hand-held pneumatic samplers or tracked percussive samplers.	+	Window sample and windowless sample boreholes can be a quick and economical method for obtaining soil samples, which are recovered by inserting tubes of varying lengths into the ground.
