- The Surge protective devices(SPDs), suitable for residential,commercial and industrial appications, are designed to limit transient overvoltage and run-off lightning currents.

- It provides reliable protection from the destructive effects of lightning and switching



- are lightning current arrsters, they can handle and divert high energy from lightning.

-they are necessary when the installation is exposed to direct lightning(for example when the buiding is equipped with external lightning protection system or powered by aerial lines).

Goldfinder’s HOW TO DIY ONE OF THE BEST METAL DETECTOR CIRCUITS is a premium Interactive video Tutorial made after ELECTRONIC GOLD PROSPECTING SHORT MOVIE and is focused on the Goldfinder Metal detectors, and how anyone can make a decent power metal detector for themselves. My Goldfinder XTR Metal Detector has been very popular in the past, so I decided to create a series! As with Gold on the Beach 6 Platinum, and GOLD ON THE BEACH 10, we continue to provide helpful how-to videos and movies, with helpful hints and tips we have learned from our many Treasure Hunting Adventures. See our 10 live gold finds on camera and learn how and where to find Gold nuggets with our video, – how natural Gold occurs. Gold on the beach and finding large Gold nuggets is always exciting, so come watch this show with premium content.

Important: Read this description
Finding valuable items is all about finding the right spot to detect and not about buying an expensive detector except if you want to find gold nuggets, then you will need every advantage you can get, so you will need to spend quite a lot of money. If you want to build a metal detector with decent performance go to the on line shop and buy a kit or two at —-http://www.silverdog.co.uk/shop/index.php?route=product/category&path=36
They are tricky to put together, but if you are careful, you can make a very competitive metal detector for a fraction of the price. This video is accurate and specifically designed to make it work. It is not quite as good as the Goldfinder XTR, but it is none the less very good. You can however use my smaller Goldfinder mono search coil at http://youtu.be/EWwWE3YpEqA. With this circuit as it has a similar power output.
Important:-There is a problem with the circuit used in this video. The round silver transistor top left hand of picture in video (2n2222A) is twisted and so the tag should be facing down not up as in the picture.
The people who design these pulse induction circuits are the technical elite. Everything I know about the Barracuda legend metal detector is in this video so don’t ask me questions I can’t answer. It is a very good detector circuit for water, salt, and normal ground conditions, – even under water. Not good for Australian Goldfields because I believe the balance is far too slow at compensating for highly variable ground conditions. Yes it will find fishing hooks and such but if there is gold you can bet it will not miss that also, it as it responds to gold items with a very clear and loud signal. But above all enjoy the project.
