the air filled dome is seperate filled with air and sealed. There is a gap from 3mm between the strobe and diffuser that is filled with water. installing the diffuser is very easy and stable ... fixation with 4 screws in pvc.
I am planning a batch off the little strobe below. But i need to know if there is anyone interested in such a device before i order all the parts that i need. It is not my intension to make a commercial product! Please send me a mail if so. (email@example.com) I will keep you informed then about the progress off the first batch. (also designed the triggerfish). Price would be prox. 70 euro. So if i get a enough response i will make a batch. 3 WP-members are testing the strobe as we speak.
