I have an etrac, and have used minelabs for about 12yrs, yes they are a weighty machine, but with a harness, that is not a problem. I would not be surprised to see minelab launch a very light machine in the next few years, similar in weight to the deus, and with the same degree of fine adjustment provided by the deus. XP have set the benchmark, now others will be chomping at the bit for a slice of the market!
