Hi there, I've recently built Baracuda PI, and it works very well with a mono coil I've built, 23 cm diameter with 0.5 mm insulated copper wire, 22 turns, about 392 uH, but I know this awesome circuit can give more. 😎
For now, I'm obtaining a sensitivity of about 10 ? 12 cm for...

What is most important when comparing the 2n5484 jfet to other jfets, especially in the Geo-Baracuda
I don't have a 2n5484 jfet and have been looking at datasheets for possible replacements.
George, I think you must have chosen the 2n5484 instead of an extra 2n5485 in this circuit for a specific reason.
What could this reason be?
I am wondering what part of the jfet... -
Baracuda Build (silverdog kit Rev2)
Intro:
I set out to build a few of the kits available to familiarise myself with pulse detectors with an aim to designing my own pulse detector...
During the process I aim to fully document the builds and provide documentation for those that follow (assume this is allowed)...

Is my Baracuda operating as expected?
Hello Forum,
I’ve assembled a Baracuda Kit from Silverdog and now I’m in the process of setting it up.
The coil I’m using has a diameter of 25cm. It’s made of 0.5mm enameled copper wire with 23 turns (iirc). Resistance is 1.6 Ohms. As I don’t have access... -
Baracuda problem, beeps once
Fellow metal detecting zealots,
I've recently assembled a Baracuda kit from silverdog but can't get it to work. I'm using a home made coil (25 cm diameter, 22 turn 0,45 mm copper wire) and a 12V battery pack. Whenever I turn the power on the Baracuda emits a clear short beep and then turns... -
New bara with no sound. Problem ahead.
I built baracuda from silverdog with original parts. I turned on and nothing happens, not a sound, not a beep. I noticed that the IC 7760 very warm. So I look all components and discovered that is IC LF412 is wrong inserted. After correction the heat of 7760 is gone. But still no sound.
I use... -
baracuda setup procedeure?
hi all,
Built a baracuda kit from silverdog, must say excellent board and kit. got it up and running first go!, detected gold bracelet at 50cms! but a lot of tone from the speaker to keep it sensitive, when i turn down threshold to less or no noise it detects 1/3 of the distance. is there...
