I have a 250. Very good starter. No need for a pointer. As you learn the ropes, you will find that ( I believe) you will not need the ponter. This is how I "pin point" using a detector. Sweep left and right. "Visualize" the ground where the beep (BONG) occurs. STEP AROUND 90 DEGREES. Don't just sweep , but actually step around the target. Then, again, sweep left and right. You have made an "X" on the ground. The target is at the X. Shorten the sweep, step around, again, if needed, to make the X smaller. You will soon be digging within an INCH of the target..... without a pointer. I have been hunting 40+ years. This TRICK will save you time and digging when you learn how. I WILL admit I use a pointer. A Vibra-probe 570, but only to push it through the dug dirt if my signal disappears from the hole. TTC
