I had the same scoop you have. I thought it would work too. It failed miserably (on the third hunt with it). You don't need to get a Stealth 720i (I did though and don't have any regrets) but spend at least enough to get a good sturdy one.
You can see I used the bend-over scoop rather than the short handled one but, it wasn't the handle that failed, it was the basket that collapsed.
Here's about the LEAST scoop I would want. About $67 through Colonial Metal Detectors...
