The 250 has pinpoint and 5 programs-the custom program you can set and once you turn it off, it keeps the program exactly as you set it.....I have played around with mine and got mine set pretty good.....I like it so far....it is killer on nickels and is alot lighter and easier than some machines.....I wish I had gotten one sooner....I dont know if it will help you find more or not but it makes it a little better machine.....my buddy has the 150 and he likes it but he wishes he had the 250......he won his as the grand prize at a local club hunt.....
We have both and I definitely like the detailed info on the 250 more. It helps me to know about how deep the target is and I like knowing more than if it is just a coin. I think that it is worth the increased price.
