GPZ 8000 vs GPX 5000 (and a warning to those with sperm on board).

[Jennifer-007]

Dave Stewart posted a great video comparing the 8000 and 5000, Woody commented on it and all of you YouTube UN-Influencers running around with your “nanner nanner nanner we got our free ones first” 8000’s who want to have little Youtube Un-Influencers need to watch….

Good luck carrying your pin pointer and pick, holeeee hell, makes you wonder if any of you will be able to have kids after a few years of using the 8000, seems the RF beam width is as powerful horizontally as it is vertically, wear lead pants sperm carriers. 😳

Minelab, where coils aren’t the only thing we contribute to the lack of delivery of! Bloody epic, they should hire me to do their marketing. 🤣

That all said, with the lack of Clint Eastwoods and John Waynes as role models, being replaced by men who need help at the auto parts store to change a wiper blade and are in touch with their feminine side, we probably won’t notice a difference.

Forgive if already posted…

PS, can an admin create a GPZ 8000 sub group please.

When I viewed Woodys' post, I was not amused. Get them lead shorts before they run out! Oops lead and all other heavy metals are hazmat in more places everyday!

Pretty soon, people are jumping off bridges afraid of their own shadows.

We are surrounded by ionizing and non-ionizing radiation. Always have been, always will be. For the uninitiated, "ionizing" radiation can remove electrons from atoms, including human cell tissue. The fact is we are bombarded every day with ionizing radiation from earth and outer space. X-rays are most common and the most regulated in terms of exposure to man-made x-rays. Dosimeters are worn by those working in potentially high radiation environments. How many rems/Sieverts have you been exposed to?

Non-ionizing radiation (RF) does not alter atoms and cell tissue is unaffected. How much power (measured in Watts) is considered a "potential" hazard to human health? Microwaves were found to cook meat! Bell labs engineers noted being warmed up in the path of microwave transmitter energy! That's one of the reasons safety provisions are in place in the manufacture of microwave ovens. Find out the facts.

FCC RF Safety FAQ:

https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-division/radio-frequency-safety/faq/rf-safety#Q9.

From the document:
"Many countries in Europe and elsewhere use exposure guidelines developed by the International Commission on Non-Ionizing Radiation Protection (ICNIRP). The ICNIRP safety limits are generally similar to those of the NCRP and IEEE, with a few exceptions. For example, ICNIRP recommends somewhat different exposure levels in the lower and upper frequency ranges and for localized exposure due to such devices as hand-held cellular telephones. One of the goals of the WHO EMF Project (see above) is to provide a framework for international harmonization of RF safety standards. The NCRP, IEEE and ICNIRP exposure guidelines identify the same threshold level at which harmful biological effects may occur, and the values for Maximum Permissible Exposure (MPE) recommended for electric and magnetic field strength and power density in both documents are based on this level. The threshold level is a Specific Absorption Rate (SAR) value for the whole body of 4 watts per kilogram (4 W/kg). "

One kg equals 2.2 pounds. A reasonable estimation of the power density in a GPZ 8000 is 5 watts. Power out = power in. Published power consumed as input from the battery is 47 watt-hours. That's 4.7 watts for 10 hours.

A 150 pound (68 kg) person can safely absorb 272 watts. That's almost 58 GPZ 8000's.

Is there a debate?

In a debate class, we learn to take any issue and debate the case on one side then turn the tables and debate the other side! Selecting the most effective wording makes the case in either case!

Sensationalism of the unknown drives the public to make irrational decisions related in support of more regulation. The net result is over-regulation. Look to California for leadership in this arena.

MegaTEM:

MEGATEM is a high-powered, fixed-wing airborne electromagnetic (AEM) survey system introduced in 1998 for deep mineral exploration. It uses a large transmitter loop to generate a dipole moment exceeding 1 million Am ^2, improved to over 2 million Am ^2 (MEGATEM II), allowing it to detect deeply buried conductive ore bodies.

Spoiler alert: It uses 40,000 watts, 2,000,000 Amp-meters squared. Coil Amps x square meters area within the coil (squared). The crew sits in the middle of the Transmitter coil.

The MEGATEM fixed-wing transient EM system applied to mineral exploration: a discovery case history - Canadian Society of Exploration Geophysicists

In the mid-1980s, Geoterrex (later Fugro Airborne Surveys) introduced the GEOTEM system, a fully digital airborne electromagnetic (AEM) receiver, using the same transmitter that had previously been used, very successfully, on the INPUT system (Annan, 1990). The GEOTEM system is mounted on a twin...
