Black and white fishfinder

[BjarneK]

I am looking for a new fishfinder with the following requirements:

1. Black and white screen (for better visibility without backlight).

2. In-dash mounting of display.

3. Simple GPS integration showing speed and maybe distance and bearing to a waypoint.

4. Shows depth in meters and speed in knots.

I thought that I had finally found a suitable product in the Humminbird 718. It has NMEA input of GPS position and even NMEA output of depth.

Unfortunately it fails on the fourth point: You can get a US version that shows speed in knots, but not depth in meters. You can also get an international version that shows depth in meters but only speed in kilometers per hour, which I have never heard anyone us at sea. In Denmark where I live, we use meters for depth and knots for speed.

Do you have any suggestions?

Thanks,

Bjarne
