Seems a lot of people like Gorilla Gloves. They look like gloves with good grip and sensitivity and a nice price. But how are they for protection from the sharp objects you can sometimes run into while digging?
I use the GG's from Amazon, think they were 5 dollars a pair. They give a little protection but if your hard core and not careful. They will not protect...Nice grip though.....
I use the cheaper ones also. Not just metal detecting, but other uses. Thinner, more flexible than leather. You have some feeling through them. Hot in summer. Adequate protection from most hazards. You can machine wash, also.
I buy PIP MaxiFlex ANSI-rated cut-resistant work gloves from eBay.
They are super-thin, snug, and have a rubber coating over the working half. Very little loss of dexterity. Eight bucks a pair and available in five sizes. I tried a pair, loved them, and immediately ordered three more pair.
