Out of these eight instruments, Bhaskara was fond of Phalak yantra, which he made with skill and efforts.

He argued that „ this yantra will be extremely useful to astronomers to calculate accurate time and understand many astronomical phenomena‟.

Interestingly, Bhaskara ii also talks about astronomical information by using an ordinary stick. One can use the stick and its shadow to find the time to fix geographical north, south, east, and west. One can find the latitude of a place by measuring the minimum length of the shadow on the equinoctial days or pointing the stick towards the North Pole
