Obscured Catapults
Rules:
Normal Sudoku rules apply.
The grid is covered in fog.
Placing correct digits will reveal surrounding cells.
Guessing is not allowed.
A catapult comprises of a circular bucket attached to a T-shaped fulcrum.
A bucketed digit X gets flung over the fulcrum and lands Y distance away from the bucket, where Y is the digit on the fulcrum.
No other instance of X appears between the landing cell and the bucket.
E.g. if R8C7 = 3 and R9C6 = 1, then R6C9 = 1 and R7C8 =/= 1.
Clarification: Digits cannot be catapulted out of the grid.
Try it on Sudokupad.

Nice idea and great puzzle. I found the middle quite tricky. Thanks!

The ruleset also reminded me of slingshot, just with the orientation of the clues being diagonal instead.
However this turned out to be a slight disadvantage as while slingshot rules count from the end of their arrow, here the catapult starts from the catapult itself, so I had to keep myself from being off by one a few times :)

The new index rules reminded me of slingshot. Tricky puzzle! Thank you very much for creating and sharing.
