I have had one since they came out. The only issue I had was a broken wire on my transducer this winter. That was my fault tho. I really like the 30. It has the same sensitivity as the 28, but with more adjustability.
Would recommend the 30 for sure – the new transducer is the real deal. To me the gap between 28 and 30 is similar to the gap between 12 and 28. If you need a new flasher I’d either go cheap and get the 12 or go all in and get the 30.
