I've done the same as Sparky with similar results. In fact, the lock mechanism is really my only complaint about this anchor. It's a bit tough to engage or release. That said, this anchor works better than anything else I have tried, and takes up less storage space as an added bonus.
When I pulled into our party spot last weekend, one of my friends saw the anchor for the first time and yelled over asking what I was doing tossing a bear trap into the lake.
