The first winch anchor (aka ground anchor) we bought was dubbed “extreme”. It came from a UK supplier.
It was a bit of a monster to carry around but it did sort of work for a while.
It was always getting bent out of shape and needed constant straightening. It finally gave up the ghost when it met an underground rock. At this point we decided on getting a replacement.
Pull-Pal Winch Anchor
The replacement was a Pull-Pal. So far so good. 6 years of training work and still going strong.
It’s also far easier to carry around and store.
Great bit of kit.
