has anyone tryed wireless insturments I've seen kits you can get and put on your engines that will send a signal to laptops or even a smart phone. looks like a good idea as opposed to replacing them all on both control statoins. and anyone have any suggestions for a nice depth finder

Here's one that is not only wireless but needs no electricity at all
