Except for not having a gain control, the
Furuno First Watch is a great unit. I have had a few 30-40ft sportfishers sneak into the 1 mile ring undetected, while at the same time, picking up
dolphins breaking the surface of the
water.
Range to 24 miles is accurate. Display only in a dedicated iPad on our boat. If you use TimeZero for
navigation, you can overlay the radar. However, if you use
wifi to port your
NMEA data through a multiplexer, you will need to change
wifi sources to view the map data and will lose your
depth, speed,
wind, etc in TimeZero, until you switch back to your multiplexer. Not a big deal. I have no difficulty seeing where we are in relation to the radar screen and translate that mentally to the nav map.
We use iNavX and were using a Brookhouse imuxST until it crapped the
bed last month. It appears that Brookhouse is out of business, as their website is dark. Not surprising. The guy is an absolute jerk....but the product was good, when it worked.
I would recommend the DRS400 wholeheartedly.
