Looking for a technical explanation, not opinions based solely on empirical data. Maybe someone with knowledge of electronics/electrical theory can provide some insight. Not trying to argue with you, but the "language" of the machine is a little vague, wouldn't you agree?
I guess after almost 5 years with an F2, I don't know the language?
I guess I don't know what a depth bar does either?
Ever notice
no one else has ever said the depth bar on the Fisher F2 indicates a bad target? Not sonsors, not other F2 users, not Fisher in their manuals...
Opinions are fine Digger, but when you start preaching them to new members as FACTS that is where the issue arises.
The F2 is the simplest machine out there! Learning it's language is simple...simple...simple... it's nothing special since there is 4 tones to know, and maybe some nuances to those tones, but still a monkey could learn the F2 in about 100 hours!
Regardless if they have 10,000 hours, the DEPTH bar will always indicate DEPTH...other wise Fisher would include in their manuals that the DEPTH BAR is for TARGET ID...
Wonder why they didn't just make a depth bar instead of target IDs? Because the DEPTH bar has NOTHING to do with an object type or kind.
When you tell new members something that isn't even remotely true, you are then doing the exact opposite of what you are trying to accomplish... you are then doing them a DISservice!
Depth bar jumping has NO FACTUAL basis on a targets kind, nor can they then leave the target 99.999% of the time, OR 100% of the time, because you are telling them W R O N G no matter how many rolling smilies you post you are still WRONG.
Your F2 doesn't perform THAT much different than the other MILLIONS of F2 sold, and a depth bar indicates depth...regardless of pictures you post, regardless of what you say works for YOU, you are still spreading misinformation!
I've tested your theories, both jumpy numbers... You are WRONG...more than 5 times I have had numbers jump from 00, 68,72,78,99,00,77, etc...you say to leave it.. it's 100% of the time junk...WRONG.... that time it was a nice half dollar!
Another time, jumpy numbers all over the place with the F2, YOU say leave it because you KNOW it's junk, and we shiould leave it to according to what you spread as facts... well, it was a quarter spill of 5 quarters!
Seen it with other targets too... jumpy numbers do not mean its junk! No matter how many times you say it does, it does NOT!
Jumpy depth bar can be due to target orientation in the ground.
That is why we are taught to turn our bodies 90 degrees to see if the target clears up!
There could be multiple targets in the hole. One above the other therefore you are going to get a jumpy depth bar.
The curvature of the ground, can cause jumpy numbers because it takes longer for the signal to get back to the coil from the low spots!
The distace you hold your coil while swinging can also make a depth bar jump.
NONE of those examples mean that it is a junk target....so where you get your 99.999% - 100% of the time junk is beyond me!
If you are going to present yourself as an authority on something, you need to make sure you are right about what you teach...and I have shown 2 examples already about how you are wrong with your theories that you keep spreading as gospel!
You are not doing the new people any favors by starting them off with misinformation! I'm sure that isn't what you're trying to do, even if it is what you're doing.
When you can show some factual data on how a jumping depth bar indicates a junk target, we're all waiting to see that... although I am an old man, so I don't have long to wait....so don't give opinions, give some facts....
