Well you've done one thing right! You bought a great weapon.
The first time you read the hand book it would of really made no sense at all. Normal
after using it for a day of frustration.... a bit of logic comes into play after reading it again.
This re reading after use will go on for a while.
A good tip is to photocopy/scan the instructional pages. And take out into the feild to make a quick references to.
The main menu select is one that should be written down in scroll order.
this can make it less stressful out the feild if you where the volume is in the order etc.
Practise going into the menu and open up the first choice. Look at the margin of variables, and where the default marker is for and average start guide.
Close it and then scroll down to the second option and open it up, do the same again.
I beleive so many people out there dont use their minelabs to their full potential in correct settings for where they are , coil set, swinging speed etc due to not fully understanding the variables.
And one of the biggest I beleive is simply the threshold.
I cant fathom how so many people just say leave it at 1'oclock!
One can just turn it on and run it default, and you will find targets no doubt at all.
But minelab offer you a detector that you can adjust and finetune in MANY ways to get the best possible outcome.
You could have a scenario of two exactly tuned machines, same model, coils etc, yet one person wants to swing faster and cover more ground, and the other wants to swing over the same area nice and steady, slow swing speed.
THIS WOULD BE WRONGLY TUNED.
As minelab even cater for your swinging speed. Set it very slow and use it it fast, you will probably find it noisy and erratic. A simple thing like not understanding this could lead to adjusting the wrong setting to counteract the noise.
Obviously do the course, meet some great people doing it as well. Some YouTube clips are to learn with, dont take all of them as gospel but.
Be patient, they can do your head in at first.
Most importantly.... you've made a great choice of detectors!
