I sold a ton of Raytheon stuff back in the day that was supposed to read down to between 600 and 1500 feet. Modern combination GPS/fishfinder units should easily see 600 feet and some can pass 10,000 feet. Fishermen use these depth ranges. For sailing strictly to keep off a sandbar, the first 100 feet are important. I use a Standard Horizon DS41 unit that fits in a 2” hole and can forward NMEA data. In theory it reads 2-600 feet, but given my old transducer I have no idea if I could actually see that far. Offshore at night we used to see thermoclines and other stuff that looked like it was 300-400 feet deep. Joe Coquina

I suspect there are “professional” units that will do it, but also suspect they are more expensive than the units we would buy for our recreational boats. Maybe Fred Street can weigh in on what would be needed for greater depth. But my question is” Why do you need depths over 200 ft.?” Rick Brass Washington, NC From: CnC-List [mailto:cnc-list-boun...@cnc-list.com] On Behalf Of Jeremy Ralph via CnC-List Sent: Wednesday, February 22, 2017 12:06 AM To: cnc-list@cnc-list.com<mailto:cnc-list@cnc-list.com> Cc: Jeremy Ralph <jeremy.ra...@gmail.com<mailto:jeremy.ra...@gmail.com>> Subject: Stus-List New sonar transducer Planning to install new thru hull transducer when I haul the boat in the coming weeks. Trying to decide on: i) a simple depth only display, or ii) a more elaborate chart plotter with depth. For chart and depth, I currently use my iPhone in a waterproof case on a RAM mount. Navionics for charts and for depth a SonarPhone TBox with an in-hull transducer. This works fine for my purposes but it would be good to have redundancy and something that works for deeper depths (>200ft). Any recommendations?
