If you're gonna be a miner, sooner or later you'll need to know what you're doin. A little geo-chemistry is very handy to test the waters you are in, as well as monitor those extractions of precious metals. Between the two, you can pretty much tell if that prospect is worthwhile or not. A lot of gold is overlooked cause it don't look like gold at first. A simple extraction on the spot can tell you in minutes if you are where you want to be. The instruments below are the best in the industry, rugged,  dependable and very cheap for what they do. You will want them in your box like a fisherman wants lures and tackle. Without them..you are just guessing.

This PH meter reads in any solution, 0-15PH, floats, and is acid-proof, etc. I have owned one for the past 12 years and have  replaced probe tips 3 times. It is a part of my prospecting kit, and very handy checking streams,rivers, mine waters and  of course, gold leach mixes. Without this I would add too much of this or that, and only be guessing. A "Must" for anyone in the gold business. The digital readout is accurate to ( .1), and will last through many seasons of prospecting and extraction work.

This is the "Deluxe" model ORP Meter, with more sensitivity, better readout, floats (a big item) and the reliability of all Oakton Electronics test equipment. These fit in the pocket for travel and handle easily, has all the  instructions, guarantees, batteries, ready to work for you.

TDS-Meter This is the final piece of the puzzle, as the TDS meter tells you how much "Total-Dissolved-solids" are actually in that solution you are trying to extract........or at the thermal well or gold seep.."Is there gold in that water?" This meter, the same as all we sell here, comes with 4-1.5v batteries, is rugged and dependable, company guaranteed, replaceable tips and reliable Oakton Name. Best of all, it is VERY reasonable for what it does. I carry all three types of meters on consulting trips and prospecting, and consider it mandatory as a gold pan.
