Not everybody has the money or wants to spend their money on a quality pinpointer right away.
I know all about them, how helpful they are, how fast you can recover things with them...I am a big fan.I
If she has the money for sure get a good one, sounds like she is on a budget so maybe not right away.
When I started I had nothing but I bought the HF one pretty quickly because I couldn't easily find the dirty coins and targets mixed in the dirt or in the hole.
Yes it was low quality, the switch broke within a couple of hours and it didn't go real far but it was still a godsend.
I had absolutely no regrets buying it and using it for three months until I bought a Propointer and then I retired it with honor.
