[QUOTE="WTM, post: 5175114, member: 6230"] its connected to the nmea 2k net. really simple to install and the steadycast sensor is mounted upside down in the storage bin. point 1 or 24 dx is connected the same and you can pick and choose on which data that a particular mfd will use. its all pretty simple to me, lol, i have a BSEE an AAS in industrial electronics but the last 23 years ive been working in telecomm. i just used what i know about RF and microwave and apply it to sonar. kind of similar in a way. when i pop a waypoint i have to adjust for the gps at the console by marking it behind the cover or structure about 10 feet. that usually puts me right on it and then after i get thru fishing ill check with 200khz 2d to very and re-mark. if not youll be off 9ft from one direction and 18ft when heading from the opposite direction when trying to find a waypoint. si is a little different because to the slant range that is the actual distance to the target. the closer to the xducer the target is then the less accurate the waypoint. targets marked at a farther distance are more accurate. here is a drawing from one of humminbirds engineers that explains it in detail. [ATTACH type="full"]112202[/ATTACH] anyhoo, dont know jon graves but worked with joan graves with bellsouth years ago. maybe they are related, lol. [/QUOTE]
