can you tell me what the difference is between these 2 transducers are ? im running the 83/200 on my hds7 and on my 28hd im using the 50/200. will the 50/200 work with a hds 7 ? im thinking about selling the 28hd and upgrading to another hds7, just wanted to know about the ducers, and will the same power cord work for the new hds7 ? thank you guys !!

The 200 khz has a narrow cone angle, the 83 khz is a little wider and the 50 khz is wider yet. The wider the cone angle the better penetration in dense, deep water. If you are fishing salt water and 100 feet or deeper then choose the 50 khz. In fresh water the 200 khz is the best all round choice but in a situation like I had at Shasta a couple years ago I found fish in 60 to 70 feet of water. They didn't show up too well in 200 khz and I couldn't see my drop shot beyond 40 feet or so. When I switched to 83 khz not only did the fish show up better but I could track my drop shot and the worm all the way down, stop it right in front of the fish and watch them bite.

The power cords and all connections are the same with all HDS units. Cables, cords and all connections on Gen 1 and Gen 2 HDS are both the same.

thank you ken !!, will the power cord and ducer for a 28hd work on a hds7 ? i plan on changing the 28 to another hds7, so i will have both units hds7's. i have the 50/200 ducer on the 28 right now. thank you again for the help !!

The transducer is the same from an LCX to an HDS unit.

As for the power cord, I would remove the three wire power cord that came with the LCX and replace it with the two wire power cord that comes with the HDS. To power the NMEA 2000 network you will need a power node with the HDS system.
