Jeff at Vesper Marine
offers one of the best customer support groups that I have found in decades in the marine
business. You will get a response to your problem.
I have had both the 750 & 850 and found the 850 to be outstanding. I can't recommend it enough! Low power
drain, great filtering options and a fantastic anchor
watch system. Coming out of Panama
I could filter out all the vessels that were not a concern.
My suggestion is to stay with the 850 and put it thru its paces you will NOT be disappointed.
