Whites Surf PI schematic

[jladre]

Hello everyone,
Can you share lastest version Working TESTED surf pi (for underwater) ? i download 30files and almost everyone of them is different. i confused i want to make waterproof surf pi version for saltwater like scuba tector...

thanks.

I think you are looking like this https://youtu.be/HYuJVvO3Jn0 it has the same layout as homefire share to you.

[homefire]

Not Sure. Maybe way back in the start. Look in the Projects board under same.

any gerber or .LAY file of this ? thanks for help

Just use the Schematic Silverdog shows on his webstore. [ATTACH]39857[/ATTACH][ATTACH]39858[/ATTACH]

Do you use 9v battery???

I used 3 lithium ion 18650 battery in series.

Her is what you are looking my friend. Surf 1.2 but problem is if you use in saltwater you will be digging targets at depth of 1 foot or more..but stable even in black sand.

Jladre, so true! This is exactly what I'm aiming for.
It will be additional (the fun) detector as a companion to my infinium ls.
No problem about black sand, have none and places where I hunt are not so cute and sandy. Lot's of pebbles, rocks...
My concern is to build tank like coil to handle such terrain.
Do you have any recommendations - specs on coil?

300-380 inductance is advisabe, use 24-26 awg copper wire, just stay on 6-8 inches diameter coil for easy pinpointing. Ordinary mono coil is easy to made.

For salt water pi just nevermind shielding the coil.. your machine will work in max performance without the shield but fir inland use better shield it.

I'm using low capacity microphone cable(tasker c 129)
Is there any procedure to gb/tune surf 1.2 to the enviroment? All I can set is the delay, treshold, volume and adjust dumping resistor. Coil is mono.
I have neutral ground but my intention is to build a small detector for snorkeling. I'm not trying to build depht monster. I just need a stable machine with as little as posibile false signals.

You won't have the issues in Salt water. Wait and See. Garret did not even Shield the XL 200 because it was not needed.

"
But I'm still looking for the answer if it's normal to get a response while tilting coil?
I tested this out on two different locations."

With that detector Yes. Your causing a Variation in the Ground Signal.

Whoops somehow I thought I was answering in the IDX thread

Sorry

The only way I can get mine to work properly is to keep the two Tx and Rx cables along with the shield separated all the way to the PCB
