When I got the new replacement recorder last week, I was shocked on how nice it was. The recorder has a nice color screen. The unit has a built in rechargeable battery that last 30 hours. My old marantz pmd620 batteries only lasted 3 hours. In addition is a tiny bit smaller which is nice. The shell is stainless steel and beautiful. Recording is simple just slide the switch up to record and then you can hold it down and it rewinds like a tape recorder. That is awesome if you want to do a instant read back. Once you are in record you will see a bar on the screen bouncing up and down in red showing the voices are being recorded. It has unlimited tracks like the marantz pmd620. There is a new button that allows you to start a new job and keep the depositions or court docs separate. They added a time date information on each recording so you look and know instantly the date the recording was made. Above all the units recording sound better than the marinate pmd620. I tried both without microphones and the new one pick up voices better. One more thing when you plug the foot pedal into the recorder, you can now slow the voices and speed up the voices on the recorder. Amazing. My old marantz pmd620 could not do that. Overall Martel made the new unit superior in every way over the older marantz unit.
