Thanks to Phistomefel and his challenge which provided the inspiration for this puzzle. I made another nonconsecutive arrows sudoku a while back called Club Med, but it was completely different to this.

Rules:

Normal sudoku rules apply.
All orthogonally adjacent digits are nonconsecutive.
Digits on arrows must sum to the totals in the circles.

All comments, ratings and feedback are very welcome and appreciated.

Good luck :)
