Excalibur II nulling question?

[TheDualFieldBandit]

I'm new to the excalibur II 1000 had it for a few weeks now and I'm wondering if it's operating OK? I know it's suppose to null out going over iron but my excal seems to null out for a long time? I was using it in a park going some what slow with the coil sweep speed went over iron it nulled out kept it going at the same speed right over a pull tab laying right on top of the ground about six inches from the iron. It didn't pick up the pull tab? When the excal nulls am I suppose to stop the coil and wait for the threshold to return? Or should it be picking up nonferrous items mixed or in close to the iron? When I got home I ran a couple of air test with a gold ring and some bi metal coins containing iron. The unit seems to era on the nulling side of things. It would pick up the gold ring if it was in the right position and if they both (ring and steel coin ) were further away from the coil and the closer I got to the coil it would null out quicker. I'm wondering if I'm missing some targets by this. I've been using it in the water also sometimes I'd get quick tone right into a null or sometimes from a null to an adbrupt tone back to the threshold. Any advise???

What are your settings at? Size coil? Seems a bit strange. Lots of question at once. The null will return as a errrrr! sweep across the scoop to return to your low smooth threshold. This is important as most of the gold that gets dug isn't the loud discriminating tones you'll hear. There always will be some loud gold but most is just a barely break in threshold!

Thanks good questions! The excal set up was in Disc1 (off) Sens at 1 (all the way down) vol maxed out and the threshold was slightly louder than a mosquito hum.

My sovereign did that yesterday and i have had sovereigns since 1992............. had the first one and every one since..........it would not quit nulling i would pass the scoop across the coil it would still null ........Turn it off turn it back on change spots throw a coin on the ground it would not pick it up..............Then what seemed like forever it would start working again ............ Then start that nulling again........... Like i said i have been useing sovereigns for 20 years so i know how they work and how to set them up................ So back to Minelab in the morning............

Ok all the way down may be all the way up? Try the 6 o'clock position and get away from electrical noise florescent light for sure! Go and try that and see what you get. Remember these are highly powerful machines and more isn't always better. If the sensitivity is too high it will null at any movement. I run mine at salt water beach at 5/6 some times 4 and dig targets so deep I was surprised.Too much and the BBS bounces off the ground and doesn't penetrate well. Nothing will tell you this when hunting. Except maybe no targets found!

The next time your out hunting and the null seems to long try switching to all metal and see if there are more targets that are keeping it nulled out. The Sov/Excal nulls over any target that is disced out, not just iron.
Also you should be able to tell if your sens is to high by either too much falsing (detector sounding off as if there is a target but there isnt) and also your threshold will choke or blank briefly. Slow sweeps help the Sov alot.
You can hit targets in the null but personally I dont like the performance of the sov/excal in alot of iron/trash as its recovery is to slow(in disc).

Thanks for the advise will try tomorrow. HH

I hunt in All Metal, switching over to Disc when hitting a good target. I have been ignoring the nulls, especially the shallow ones. Just to be clear so I understand. Are you saying that some gold will null out like iron? .

I found the problem with my sovereign ......... Could be the same with your Excalibur....It was not the battery's it was the connectors were the batterys connect............ So check your batterys again and how you have it connected........ Could be your charger is not giveing you a full charge........... I always have a battery pack with my detectors .......Get a battery pack for your Excalibur.......... I really don't like rechargeable battery's.......

 

[keppy]

I would say it is a battery problem ...You are not getting a full charge ..Bad charger.... Could even be a bad battery.......

 

[TheDualFieldBandit]

Thanks for the battery tips! I do not like the stock charger it has no lights to tell when it's fully charged or not!
