An Explorer from the factory in a chestmout configuration..Jimmy Sierra mad a fine one for the heavy Eagle Spectrum and even for the XLT which didn't sell well as the XLT already had been weight trimmed with excellent weighting...We all know in its present configuration just hard to hip or chest mount. Certainly a thought as many complain of the weight and ergonomics...Minelab are you listening..Personally at 68 can handle an Explorer for several hours which is an average hunt but surely could benefit the fellows that hunt all day...
