The Lowrance 3500 depth sounder and the LST-3800 are from different generations and may not be directly compatible due to differences in their connectors and communication protocols. It is advisable to check the specific wiring diagrams and compatibility information from Lowrance or consult with a marine electronics specialist for accurate guidance. Using an adapter may be possible, but it is essential to ensure proper functionality and avoid damage to either unit.
