In my opinion most of the BH models are starter detectors. If your intentions are to detect occasionally and enjoy the hobby, it will work. If the bug bites and you and you become obsessed like many of us, you'll be looking for a better detector in a month or 2.
Last year in May I started with a no-name el cheapo detector, it paid for itself in a month and a half. I then moved up to the Fisher F4 with a DD coil. It could go deeper and you could cover more ground with less overlapping since it had the DD coil. 3 month later it paid for itself. I then upgraded to the F75 LTD SE. Ran into a great deal. I still need to find $600 more to break even.
I now have 3 detectors.
F75LTD SE is the one I mainly use.
1280X Aquanaut for water hunting
White's classic ID is a loaner/back-up and I use this when I am detecting abandoned houses in seedier areas.
As you can see it's more than a hobby to me..
