Threshold : Silent Search ????

[grumpy]

Afternoon Friends;
I have been playing with the Sov GT for a few weeks now and have a per ti nent question??
Have been using the fac reccomend setup with the disc at 3 and notch at 1 and threshold on and at min hearing .
Now yesterday we tried the treshold set on the silent mode. The wife said she liked it much better she does not like babbling rambling sounds constantly (if she did she would just listen to me more). Personally I cant figure any big advantage for having it either way but the quite is good at times.
So is there a big plus one way or the other ?????? Is there a majority or strong opinion of most to use it one way or the other????

Also we are pretty trained on the coins 176 - 180 Dig It. 144 apx dig it. Any other numbers I should be adding in that are regularly good like gold rings or IH s or anything?????? I have several years on the Explorer series machines and found the numbers were mostly just confusing issues you had to learn the sounds more but on the GT it seems to be pretty much on the money its more like a GOOD WIFE than just a Wife ;; It rarely lies to you :)
Thanks for any help
Good luck to all

According to the manual if you hunt in silent mode there is the possibility of missing some deep targets or some small gold targets. Also I agree with you that the numbers are confusing on an Explorer. With the Explorer you can identify targets much easier using the Smartfind Screen and the Ferrous Mode Audio ID. Can't help you with Sov numbers as I prefer the old 550 meters calibrated to 600 on my GT. I am sure some fo teh others will be able to give you the 180 Meter Numbers for most gold rings. But if you are hunting the beach looking for gold you would be better served by digging everything except the iron signals! JMHO

One good thing about a threshold is that when you start getting into an area where there are iron targets, you can hear the threshold null and start to go slower and overlap your sweeps by 1/3. This way, you know you are in an area where there could be targets amongst the iron that are masked and that others may have missed.

In silent search mode, you cannot hear the threshold null out.

Also, the smaller, deeper targets can break the threshold sound very slightly, and when in silent search, they may not sound off.

The threshold searching is the key to finding small or deep targets. Searching silent is nice sometimes but you will pass right over a deep target and never hear a sound. In threshold when over a deep target you will hear a slight change in tone but no loud signal that you normally hear in silent search mode. If this slight change in tone is repeatable there is a good chance that something is there. Its good to practice on this with a test target to get the feel of it. Bury a coin slightly deeper than you normally find targets and mark its location. Set up the detector so you have a even low threshold tone with the sens low enough that open ground does not change the threshold tone. Move the coil over the target, you should hear the soft change in tone. If you get any of the normal loud signal bury the target a little deeper so only the threshold changes when you move the coil over the target. Check the target from different angles to get the feel of how the threshold tone behaves. This type of detecting takes a little more attention than just strolling along in silent search mode but it can pay off big....Also if the sensitivity is set to high ground mineralization can also give you a repeatable change in threshold tone which can lead to frustration from digging deep holes with nothing in them. High sensitivity is not always a good thing....

Thanks ; I had a feeling there was something to good to be true about that silent thing.
Guess it would be great if that silent worked as good in real life as theory. Only make noise at a target and catch all the targets
Good Luck to All

If your on the beach, disc 0, notch 0 and dig all to start with, i have had a few surprises with real low number gold, i use both the 180 and 550 meters but prefer the 550 aswell, just 2 days ago a definate 244 foil was a nice gold ring, i only dug it cos it gave an unusual double bling similar to the higher numbered ones, also had gold in the 490 - 500, i go more by the sound rather than the meter but it takes time

OOPs i forgot, if the disc control is set higher than the notch the notch don't work, eg if the discrimination is set to 3, all below 3 will be discriminates including anything in the notch up to 3 also. The notch is a small section discrimination and must be set above the main discrimination to take effect.

to me the threshold is a valuable tool, On certian deep coins there is no real audible signal, but just a slight rise or change in the threshold tone, these changes alret me to the possible presence of a deep coin. in silent search you lose the option of hearing these slight rises in the threshold tone, and therefore the possibility of missing a deepie goes way up ........

obviously the nubers are never perfect and can be shared by junk and good targets, but I have found several smaller rings the were in the 120/s like 123-6 , and some chunkier golds that came right at 163 ,so I like the 161-163 range if it sounds lower I find a lot of round tabs at 162 also, so in that range tone is the key. Good luck
