  1. Paulito, The atmospheric conditions you described are exactly why The UCLA atmospheric research facility I worked at in Alaska was located where it was. Alaska has extremely clear conditions and intense darkness in winter with no city light sources. I was an atmospheric research technician, running experiments there for many years. I forget what year it was that we had an intense Leonids meteor shower. But in that year we tracked hundreds of Leonids per hour. Of course our experiments did not depend on visual sightings, although we did have some of those. With this equipment we see every meteor that enters the atmosphere. Each one is recorded digitally. Our experimental equipment included a liquid Mercury telescope, laser excitation, photometers and computer diagnostics. This is one of the lasers inside of the building. Look closely for the yellow laser line. It comes out of the laser horizontally on the left, then hits a turning mirror and shoots straight up. This is the laser exiting the building. It excites the Sodium layer at 90 Km in altitude. This is the liquid Mercury parabolic dish telescope. It holds 450 lbs. of Mercury.

  2. Cool Tvan! Thanks Jim! Fortunately? My old man is an astronomy nerd :)! We have gotten up many a time at 2:30am to see meteor showers. This year's Perseid is supposed to be a "outburst" shower, so like up to 150-200/hour vs the 80/hour normally. To see anywhere close to that many per/hour, it needs to be DARK, and clear of clouds/smoke etc. I was out smoking last night, sitting near my bright porch light, so I could only see the brightest meteors. I only saw 5 in 2 hours, but they were blazin', long and bright! Also I was out there 10:30pm-12:30am, so the moon was still out, and the Perseid constellation (the general direction from which they enter our atmosphere) was still low on the NE horizon. 2:30-4:30am the moon will be down, and the "origin" of the meteors higher to the NNE. I've seen hundreds of meteors in my years, all 5 last night were pretty decent! So last night was the "peak", but they'll continue for a couple more days. Problem is the waxing moon is getting brighter and staying up later. Get out there tomorrow morning to watch earth's force field protect us from speeding space rocks! Of course, it's cool when a few get through on occasion, they make trippy collectibles for earthlings ??!

  3. Came across this article. Keep a watchful eye out and keep yourself safe my prospecting and detecting friends. http://www.abc10.com/mb/news/local/california/drug-cartels-take-to-the-hills/295393899

  4. That's too weird, never heard of such a thing. Hard to believe the coil cover could put enough pressure on the coil to deform it, changing the coil null enough to overload. Also hard to believe they accidentally used a plastic coloring agent that has conductive properties. That's the only two things I can think of that would explain what you are observing.

  5. Thanks guys glad to see that you enjoy our videos! That is what I got for the last 12 days just under 10oz. To get that I had to bush bash for 13 hrs one way and got 2 flat tyres that only needed plugging one torn wreaked tyre and a burnt out clutch. Tremain got stuck twice in steep crossings which required recovery to get through. On one section where we have to avoid the extremely rough top of the hill and drive around on the sleep side the upper wheels lift off the ground! Dangerous and exciting stuff..... love it! It would be one of the most rugged and geographically isolated areas in Australia even the station owner has only been in that area very rarely in a chopper! Will make an interesting future video.

  6. I noted this on another forum but want to do so here too so here goes. How many of you have experience with pocket gold? I've pocket hunted a few places hopping around with a little luck, mostly CA Mother lode country and AZ. Here are some good reads for ya if'n you're not familiar with it. Anyone from the east do this, like Georgia or Virginia? I'l be visiting Virginia for a few weeks this year, would love to hear some local voices.

  9. I actually saw my first ever Perseid meteor last night on the way home from work at 12: 30 am. For 14 years, it has always been too cloudy to see anything. I only saw one, but it was a fireball. Caught a glimpse of a bright object at the top edge of my windshield, looked closer and saw a bright white ball of fire with a white tail arc over my car. I had the car window down this time, but heard no sonic booms.....5th one I have seen in last 5 years now..Wonder if a dashboard camera would catch these events? The first one I ever saw was on the Interstate coming home from an Indiana Gold prospecting trip. I thought it was a low flying airplane until I looked closer, again at the top edge of my windshield, and saw it was a Green ball of light with a short green tail, like the size of the sun. It freaked me out so bad I had to sit in a gas station for 1/2 hour to calm down. Dunno why the first fireball was green in color and the other 4 were white ?

  10. Wow, That's an amazing setup with the liquid Mercury Mirror. Who dreams up these things? That seems like real world Star Trek stuff.

  11. Wow, cool Jim! Me, my wife and daughter, drove out to the lake last night, and layed in my truck bed. Saw a dozen or so, biggest hinderance was the moonlight. Relaxing though!

  12. well first you have to tell us where you found that, then I'll run right out there and see if I can do it while toting a camera,(and a shovel).

  13. I can see one major problem....... How are they going to find a camera man that is fit enough and has the balls to follow me to where I found this?

  14. The color of the tail is determined by the different gasses it passes through as it enters the atmosphere. Generally gasses are stratified in layers at different altitudes.

  15. I use the SDC 2300 to scan quartz that has been pulled out of mines...as well as the ATX. Hard to beat the gold bug 2 for this doing though, prob the best to use for this...
