"Dancer": Don't know about your area Monte but when it's hot and dry around here, the guys go wading for jewelry and coins. Only way to go.
In my younger and more mobile days I would do some beach hunting and some wading to about knee deep. Oregon coast ocean now and then, but mainly rivers and a couple of lake or reservoir areas. I lived in the greater Portland Oregon metro area most of my life, unfortunately, and while we had some hot days, it was generally moderate temperatures, cloudy, and too many rainy days for me to enjoy. I had ample shad from the many very tree-filled parks and other locations when it was hot, and sine I didn't come will gills and never learned to swim, I didn't get in the water all that often nor very deep. Mainly hunted the dry to wetted areas.
Getting around with a cane since March of '93 also kept me off most beached with sand and very loose material because canes and sand don't get along well. Nor do I know with very impaired mobility, especially the last couple of years. Any beach work I do now is where I can park close, and the freshwater sites have hard-packed ground and no sand. And while I used to routinely get out to high desert ghost towns during the summer with temps ranging from 95° to 106° and handle a full-day hunt, I haven't been able to do that for the past twenty years, and in the last five-to-ten years I am finding this old phart just can't handle higher heat like I use to. Time is pent in my house, AC at 70° or so, and I hold out for very early mornings when it's cooler. Really looking ahead to the next week when we start to shift to milder late-summer temps and fall weather coming in a few short weeks.
Even with that it's still been a struggle the last year or so with more hampered mobility and I know my detecting days are numbered. But by Sunday to Tuesday we drop to the 72° to 84° range after we finish off this week in the mid-to-upper 90's, and I have two detectors arriving Monday, one being the Apex, and I'll be ready to assemble and head to a couple of sites to put it to work. I live in Vale, Oregon which is on the far eastern side of the state, in high desert farmland, ranchland, rangeland type environment, so no saltwater hunting until mid-September. I sure hope the Garrett team has done well on this one.
