Re: Islander 36 projects in paradise!!!!!

Some pure speculation, but it may be that the electrical characteristics (impedance versus capacitance) that are used to encode the information and the scale used (e.g., some may say that every 10 ohms of impedance means 1 foot of depth to the obstruction, while others may say 20 ohms per foot) could be different based on the manufacturer of the transducer and/or what the head unit manufacturer specified. The transducers may also have different power requirements, and not all head units may be designed to source that much power. That being said, manufacturers may have realized that standardization of some of these characteristics is good, because it will reduce their costs across the industry. If that happened, whether your transducer is one that used the "winning" combination or not is going to be tough to tell without a lot of research.

Hope this helps.
