Actually there is....but this thread does not include the RACER, so i'll not harp on about its blended audio here and less amount of processing time needed in order to report. However im certainly up for anyone who wants to prove this to me out in the field with a Dues.??....and i get to pick the field....lolbefore you listen to anyone grab a deus and try it out once you try it there will be no turning back because there is no other machine on the market that you can swing like the flash and still pick up every target .when i swing i swing 1 second left 1 second right like really fast and i never miss a target .thats the one thing i love about the deus its not like normal metal detecting where you have to take your time and it takes you all day the deus is so lightening fast you can cover a tremendous amount of ground in little to no time .
Like it or not, the Dues is wireless..due to the laws of physics, there is lag...it maybe only small but there is lag. Lag is also present in the other above mentioned models due to slow and/or poor processing power combined with settings requiring a slower swing speed....and the v3i is testament to that. However i dont believe Lag is a major concern if your able to work the detector to it fullest.
No matter the brand, its you who leaves targets in the ground because of the amount of variables....the make/model you swing may well be the best there is....but you/me are mere mortal...and thats why there is always targets left behind.
If it was not for the battery issue that others have mentioned, id probably be all over the Dues due to wanting a new toy. Im not talking about the std by times, im talking going flat out in the field where swapping it out for a fresh set is not possible.
Q....Does the Dues have a built in speaker on the back of the c/box module.??
