[CA] [CA11] C120 replacement with E125

[Chuck - Raymarine - Moderator]

Tom,

Q. If I installed a CP100 with a CPT 100 and ran it to the E125 would I gain anything over just running the E125 off the internal sounder of the A68 with a CPT100 transducer?
A. With respect to fishfinding features to be added, none with be added. However, the primary advantage of an external fishfinder sounder module is that its sole function is to process analog fishfinder transducer signals. As such external sounder modules do not have additional circuitry (ex. displays, WiFi, etc.) which can be a source of signal noise which can adversely affect fishfinder performance. Typically, external fishfinder sonar modules will provide the greatest level of fishfinding performance (depth and image quality) over a MFD's internal fishfinder circuitry. Accordingly, I generally recommend that an an external fishfinder sounder module be chosen over a MFDs internal fishfinder sonar for those seeking maximum fishfinder performance.
