I highly recommend the Flare Assist for your experimental amphibian aircraft. As a new to water flying pilot and Searey operator the FA is a very useful tool to have in your safety toolbox.
It’s audial function of altitude callouts allows the pilot to concentrate on the sight picture that landings on water require along with the all-important minimal descent rate.
The FA has been helpful to assist me in developing the eye hand, motor memory skill needed to make a smooth safe touchdown. especially when landing on glassy, mirror like water. Works as advertised!
