I recently had an X125 installed with my boat. It seems to operate properly, but the water temp constantly displays 32.0 degrees and blinks. Does this mean that it's not wired correctly or the unit/transducer is faulty? I haven't had a chance to take it back to the dealer yet.<br /><br />Side Thought: Is it common for different brands of depth finders to measure 20' differences in water depth? This weekend, a buddy and I compared readings tied up to one another, and he was consistenly reading 20' deeper than me! I haved tested mine in low water and it seemed "accurate".
