I have a 998 and 958 that are nine years old now and both function nearly flawlessly . I plan to get a new boat in the near future and would like to upgrade to new technology for depth finders . Unfortunatly all I read here every day is how every ones new product has some kind of glitch in it . It would seriously piss me off to spend 4k or more to replace what I already have with something that only works on sunny calm 72* days with low relative humidity maybe . Initially I would be keeping the old units as they are shared between two different boats . If I had a problem I could just fall back on the old tried and true . How many of you that have newer units are overall happy with your purchase ? How many that have newer units with problems would still purchase the same ones again ? I don't want to buy 4k worth of paper weights . Please help me decide .
