Scoop handle attachment?

[Finderbum]

I just bought a T-rex scoop. I've been told a standard wooden handle from the hardware store will work just fine... I'm also looking at at carbon fiber one as I note Steve has developed this as a new product line.
My question is about the secondary/ attachment handles I've seen on YouTube videos, short and running at a right angle to the main shaft for a lateral grip. I don't see such an item on store sites so wondering what they are and where to procure.
Thanks

Raptor pull handle. Available on the big auction site and from a number of detector dealers. A T-Rex scoop full of wet sand is HEAVY.

George, thank you very much.

I'd go with a MOTUS handle. They work just great.

Plus 1 on the Motus handle.
