Stethoscope is the 5th in a series of sudokus that use an adapted arrow sudoku ruleset, namely that digits on an arrow must sum to either double or half of the digit within that arrows circle cell.

It has made for some fun puzzles so far, but please join me on my quest to master this ruleset!

Rules:

1. Normal sudoku rules apply.

2. Digits on an arrow must sum to either double or half of the digit within that arrows circle cell. Once halved or doubled, the value of the arrows circle cell is the value of the cell itself. For example if the digit within the arrows circle is 6, then the value of that cell is either 3 or 12 (Halved or doubled)

3. Digits outside the grid show the sum of the values sandwiched between the 1 and the 9 in the column or row.

4. In cages, values must sum to the small clue in the top left corner. Digits cannot repeat within a cage.
