"I don't like the advisory systems, they give a false sens of security."
Your privilege, of course.
We had a community of about two hundred owners/operators of our amphibians and we used to lose two or three every year to wheels down on water. They were not confined to the less experienced pilots! Luckily very few were fatal. Several of us spent a good deal of time working on warning systems.
These days the community is probably up in the six or seven hundreds, many of them Light Sport and we are averaging about one a year. Draw your own conclusions.
After saying I would be disciplined I got distracted (by my prostate!) and landed wheels up on our local runway. I wouldn't land on water after that till I had a system. It cost about $30.00 and while no system is foolproof it worked for me by requiring a positive action choice to set the wheel selector up or down (from neutral) to cancel the buzzer.
