I have a Prizm IV and the recovery speed on my machine is not slow at all as to compared to many other
machines that I've used... I can lay a dime, pulltab, and a nickel (for example) around 4 inches apart and get 3 distinct
beeps with a smooth sweep across all 3 using the 8" stock coil... I also have the 4x6 shooter coil and the objects
can be moved to around 1 inch apart (1 inch between each object) and with a slow smooth sweep, all 3 beeps are heard and ID'd correctly...
I can also use, pulltab, dime, pulltab in that order, and disc out the pulltab and pick up the dime between the pulltabs.. Great separation
and good recovery with both coils, especially with the DD coil... Approximately 4" separation between targets with the 8" concentric
coil and approximately 1" - 1.5" with the DD coil...
Great separation and recovery with the 4x6 shooter and it's what I use the most on this machine, but the 8" is
not bad either... I have many detectors, including Tesoros, Whites, Fisher CZ's, and Minelabs.... Probably the fastest
recovery detector that I have, with any sweep speed, is the Minelab Advantage with the 7.25" DD coil... But the slowest is definately not the Prizm IV....
I will say that with the Tone ID on, the higher pitch on the coins seems to hit a little quicker than the standard mode... Just an observation...
But I can honestly say, if anyone has a Prizm, regardless of the model... The 4x6 Shooter coil is a great addition.... Basically the same
depth on my Prizm IV with the stock coil and deadly in trash.....
