hey guys, would like a little help to sort through the good and bad. wanting to get a dual o2 wideband system on boat, been looking at the aitronics o2 red alert to the innovate lm-2 wideband meter and the one from fast. the more I look the more I don't know, there are so many brands out there I don't know which way to go? I am n/a 565 and adding nos . I do want a dual o2 system but can be a meter or permanent. I do like the red alert for its safety. any brands to stay away from or to stick to? thanks!
