I use a Whites Bullseye 2 pinpointer, they run about $100, check ebay & "classifieds" in this forum. A Pinpointer is a must have in my oppinion, I'd be lost without mine. My girlfreind just got one online for $40, I think it is a Tiny-tek. She seems to like it, it has adjustable sensitivity & works well. In fact, I think Jeff (site moderator) had the same one for sale with a nice holster not long ago, I highly recomend you get one soon, it will help immensely!
Heres something I found online about the pluses of using a pinpointer.................
You can find those small, unseen and evasive buried targets in less than a minute!!
Electronics won't let you waste extra time looking for a coin that is not there, when in fact, your detector actually beeped on tricky stuff like bits of foil, BB Shot, a hair pin, wire or nails!!
Savvy Detectorists use Electronic Probes to speed up retrieval of small metallic objects such as buried coins and jewelry, after locating with a full-size metal detector. An Electronic Probe can easily pay for itself with the extra coins you dig!
Avoid "Tree Root Frustration" - simply slip the probe between entangled roots to find those hidden coins faster.
Find targets that stopped giving a beep after you've opened a hole and disturbed the halo effect - metal targets can't hide from electronic probes!
A short detection distance in an Electronic Probe produces exceptionally accurate pinpointing on small targets. For example, a 2" detection radius (low accuracy) means the target lies anywhere within a 4" sphere when the target alert activates. In contrast, a much shorter 1/4" detection distance (high accuracy) means the target lies within a precise 1/2" of the probe. When an Electronic probe sounds off, you know EXACTLY where the target is - you've eliminated the guesswork !!
You rarely have to re-pinpoint with your main detector. Why re-scan for an elusive target with your 3-4 pound detector when you can use a 7 ounce probe?
Electronic probes, when properly used, avoid damaging collectibles by alerting you JUST BEFORE the probe actually touches a target! Non-electronic metal probing rods indicate the location of a buried target by actual contact. This presents a definite risk of nick damage.
Metal rod-type probes and screw drivers can fool you when they contact buried non-conducting objects like glass or stone. You won't get tricked with an electronic probe because it will not respond to those non-metallic objects.
An Electronic Probe can add to your enjoyment when hunting with a detector-less partner or child - use your main detector to mark the location of buried coins, then let your assistant retrieve them while you continue to "spot" more targets with your main detector. Kids absolutely LOVE this way of treasure hunting !!
