I currently have a functional Datamarine (old)
depth sounder which works fine, but the speed log is shot both at the through
hull (metal wheel) and display (an old Datamarine Corinthian). I am in the process of upgrading to an integrated
Raymarine E series system and have a through
hull for speed, temp, an
depth to connect to a DSM300 module (Seatalk). This through hull will replace the old speed log through hull which is next to the Datamarine sounder through hull. My question: Will having the old Datamarine sounder close to the new
Raymarine sounder confound the
depth data? I would like to have both systems operational as redundancy is not a bad thing, and I do not want to put another hole in the
boat. Thanks
