Target ID response time ?

[mtntrekr2]

I have an Ace 250 and have noticed when I am out in the park or
schoolyard if I hit an iron target it seems to stay on the id mark for a while.
I understand that this could have a lot to do with the 250 not being "THE
BEST " machine but it a very good detector for the price.
My question is. Is this the same with all types or are there faster machines
as far as the response recovery time?

Thank you for your response

Yes, but if it hits another target right away doesn't it change? There's no reason for any detector not to show the last target for several seconds.

If I swing over iron first then a coin it misses the coin if it is the coin first it will ring coin for a split second then iron. I end up rechecking a lot of areas over and over because I know I missed a lot going east to west and when I come back north to south I will find more. ( directions are just examples) I was just wondering if this is the same with any detector. I understand that the way a coin may be laying in the ground has a lot to do with the way a detector may pick it up but it seems like I spend a lot of time rechecking areas.

I also have an ACE 250 and personally I think it is because most of the time when you come acrossed iron that object is bigger than the coin and that gives a stronger singnal . When I dig a piece of irn etc. I always recheck the hole and area around the hole . Good luck.

I always recheck the hole. Just sunday I had a target saying a half and found a quarter at 1". Rechecked and found another 2" beside it. Rechecked again and found a third 2" on the other side. Checked again and found a dime down another 1". I figured this hole had to be done but there was still a 1940 wheat down 6" just off to the side.
I got lucky because there was one of the boro employees standing there watching me. I was talking to him about getting permission to detect inside the pool fence. Til I got done the hole was about 6" around and almost as deep but when I covered it over there was just a little trace of some fine dirt mixed in the grass.

If it stays on until you expose the coil to more metal or to some other conductive material such as other minerals, or electrical interference, then it's working as it should. Who would want a detector that only registers for a few seconds and then shuts down to zero again? My old Compasses would stay where the needle locked on untill I disturbed the field of my coil again, or until it was agitated again. So would my old White's. The Ace 250 should behave the same. Mine did, that is before I gave it to my daughter.

If it doesn't stay there for (at least) a very long time without being subjected to other stimuli, then it has a problem. Every detector behaves a slight bit differently than it's twin. If it won't stay there it may have a capacitive problem somewhere in the output section of the circuitry, the one that sends voltage to the meter.. Capacitors store the electricity to be used at some later time, and that can be only a nano-second duration, or as long as forever, depending on the capacitive device.

If it stays there even after you shut it off then you have a sticking meter.

Thank you for the info. I am glad to find out it is not a defect or my doing something wrong. I just have to keep swinging both directions as I have been because this place is loaded with garbage but it has been treating me good. The average has been pretty good for the most part 1 coin for 1 pulltab or other piece of trash. Found some cheap children's jewelry and have learned that the dollar signal is usually one of those foil seal tabs off a juice bottle, but I dig everyone of them in the hope of a good find.

Thank you

Hi Joe:

If your Garrett machine has a "crossfire" coil you have poor recovery time. This coil was designed to add a little depth to your finds. When they designed this coil they didn't take into consideration that by seperating the transmit and recv. windings in the coil, it would effect the recovery time when you pass over a rejected metal. This is the reason you can find additional targets if you search at 90 degree angles to pervious patterns. I hope this helps.

I had a detector that was so slow in retuning when in trashy areas that it was very difficult to reswing or X the target in order to pinpoint. Very frustrating to say the least. When hunting under these conditions the display would bounce all over as trash was swung over so the original reading was gone nearly instantly, yet was very slow to retune when swinging back over. This was a machine with the crossfire coil BTW. I no longer have it. Have gone to another brand that holds the id long enough to make it easy to read and retunes from one target to another with effectively no delay at all. All this said, the use of a smaller coil in heavy trash improves the perfomance a lot as the machines don't have to try to identify so many targets at once.
Dig deep and often,
