Garret Ace 250 things you may wanna know if new
Only dig signals that consistently ring as one tone. If it jumps from low tone to high to low etc, keep walking. Once you get more experience then start digging the iffy signals.
-Sensitivty
keep sensitivity down.Try always with 4 bars
sensitivity.If the soil you are hunting allows it,rise sensitivity one or two
bars .If you see the ACE becomes unstable,down sensitivity again .
At full sensitivity the ACE250 will go crazy and you will get a thousand
"ghost signals"
-Pinpointing
Practice pinpointing, as it is a little different. The "hotspot" is the center, front tip of the inside oval on the coil. It almost pinpoints like a DD coil. Just scan side to side to center the target then drag the coil straight back until the instant the signal stops and your target will be right there. If you have trouble with a target turn ninety degrees to the target and scan it again and you'll hit it right on. On deep targets the hotspot will move back from the tip of the inside oval a bit. Garrett has an animated diagram on their site that gives a general idea onpinpointing.
-Pinpointing:
If the pinpointing area seems too large, go to the side of the target and press and immediately release the pinpoint button. Then press and hold it and go OVER the target, as normal. That is called ‘detuning’ and the target will shrink and be in the center of the coil. Here is the reason Garrett made the oval 6.5 x 9 coil
1. Tape the coil cable straight up the lower rod. That way you can run sensitivity much higher without falsing.
2. Hunt in the Relic or All Metal Mode. If you start notching out more you will easily loose 2 inches of depth.
3. If you get a weak signal try to swing the coil faster over the target. That improves target ID and depth.
4. If the target just jumps in the coin range, it is a deep coin most of the time. If it jumps all over the ID range it is trash.
