Glissade came with a very adequate Raymarine depth finder but my search for a decent gps speedometer, at a reasonable cost, had just about pushed me over the edge. I could go on a long rant about what happens to costs as soon as you put the word "sailboat" with it, but I'll resist the urge. I found the (round) unit shown in photo one for under $60.00 and it actually works quite well, as far as accuracy, with resolution to one decimal point. the only problem is it's impossible to see in direct sunlight. I even tried several methods of shading the face but to no avail. I like things simple and cheep, but they do have to also function in the real world! In the end I ripped everything out of the "dash", filled in the holes, and started over again from scratch with this flush mounted Garmin Striker Vivid 7cv. it does everything I need it to do and more, plus it only cost part of one arm and a tiny piece of one leg. a bargain actually, when you realize it's for a boat.
