When I pull my TM out of the water to change locations I don't turn off my DF. I read somewhere on here that you would burn out your transducer if you ran it out of the water.
I don't profess to be a sonar expert, but I spent 32 years in the telecommunciations industry so electronics are not foreign to me. I ran this by a fishing buddy who was a coworker of mine and he agreed with me that it just did not ring true.
You can turn your DF on when the boat is on the trailer and if the transducer is pointed down you will get a depth reading. Because sound travels faster in water, the depth will not be correct, actually higher by a factor of 4.3 since that is the difference in speed in air vs water.
For the life of me I can not see how it would damage the transducer by running it out of the water. I can see how a trolling motor would overheat running in air, but a transducer??
Anyone else heard of this?
