MIKE,
Hi, I finally made it out today [sunday] and we went to a old house that use to be a school,church, and now is a home of someone we know. The building was built in the 1920's. Oh well back to the comparison of the garretts 250 and the whites prizm ll . Today we didn't find any coins [that was surprizing] so at that time we couldn't compare each others detector on coins. But he found a old chevy relic that he found out to be pretty valuable [found it around 5 or 6 inches down]. As for the rest of the morning not much but alot of trash.
My opinion of the garrett and of my brothers opinion the detector looks and feels good, the easy to use buttons were nice. Plus you get alot for the money like deph screen, the selection of modes you can use, over all I was pretty empressed with it.
Now for the negatives and I am comparing it to the prizms. The screen I.D. was smaller than the prizms, which my brother said made it a little hard for him to see[ he had to take a longer look at the screen to see the identifing symbols. The tone i.d. was more like a door bell sound [more or a high pitch than the prizms].
Then later on in the evening we headed out to our moms house to find some coins and we detected for about 2 hours. He found a few coins [few pennies.and a dime] and some other interesting objects. I found my first silver looking ring not sure of how much its worth. So what we did was to see how each other detectors would detect on things we put in the ground. First we put a gold necklace about 6 or 7 inches in the ground my prizm picked it up in the all metal mode but the garrett didn't pick it up with a repeatable beep. Then we put in the siver ring it did fine as with the quarter.
So wrapping it up,the garretts 250 seemed like you get alot of bells and whistles for the money, but the bigger I.D. of the prizm ll and the fact that it pick up a necklace that the garrett couldn't .
SO IN MY OPINION I THINK THE PRIZM DOLLAR FOR DOLLAR COULD BE A SLIGHTLY BETTER MACHINE.
But whichever machine you buy you can't go wrong with either of them.... GOOD LUCK AND HAPPY HUNTING.....
WODD....
