whites prizm IV info please

[Nate in Ga]

I have a garret ace 250 and have used the crap out of it for 2 years and wanted something else, I couldnt afford much and the price was right to buy a prizm IV. Can anyone tell me about this machine and if its at least a small step up from the 250?

Only you can decide if it is a step up. Depends on if you want a modern detector or one designed back about eight years.
