Ahoy all...Here's today's burning question(s).I need to replace the instruments on my P30...depth, knot/log,wind speed.My old Data Marine depth & knot/log have died and with their age, approx 25yrs old, it probably makes more sense to just replace them. My wind speed is only 3yrs old and never has worked right. Standard Horizon claims there's nothing wrong with it.So...now I'm looking to replace all of these with something I can depend on for more than a few days.Everything I have is bulkhead mounted, so I will have to 'adjust' the openings for the new gear.I don't want a 'fish finder'....as long as the fish are in the water, that's where they belong, and I really don't care where they are.I don't race, so 'big bucks' top of the line stuff isn't necessary.I'd be interested to know what instruments others have had good/bad luck with.
