I use these and rarely get a freeze up ezcept on brutally cold windy days and its still minimal... How they didnt catch on idk
ever had problems with the 3/8" thick not being enough? im pretty sure the ones I just made are 3/8" as well.. but theres a lot of different thickness options available to buy just wasn't sure if maybe I should consider getting them 3/4" or even 1" thick
In those types of cases I don't think even thicker material would matter anyway. .
I have a set ( 5 ) thermal tip ups. Not a fan of them at all. The telescoping ( antenna) flags laws bend and or break . They are not very visible from any distance so machines just run them over. They are awkward to wind up and transport. Haven't used them in years
For cold sunny days the best thing is a THIN black cover. the object is to let the sun's heat into the hole rather than retain what little there still is in the cold water. I use a cheap thin rubber floor mat. heavy enough nit to blow away, too.
Where'd ya get a cockamamie idea like that Sir? It's easy to overthink stuff. Thin is in! Truck tire innertube. 14" x 14". Done.
