I bought some cheep driveway reflector posts to put next to them, but that was to stop the snowmobiles from running them over.
My nephew lost a polar tip-up about 3 years ago so i went out and bought some small cones then put some of the reflective tape on them so at night you can see the cones and so does the snowmobilers.
You can bring a snow shovel with you and clear around your traps better, nothing is permanent in blowing snow but it will keep them visible a lot longer.And on bare ice for your "uprights" when you set them use your slush and cover the outside of the legs with small mounds and clear the tops, makes a nice cradle.
I lost two frabill thermals in a snowstorm. found one really quick after the flag suddenly went up, and the other was found doing a grid style search. Its crazy how fast the snow can cover things up.
You hadda love that flag!
I used flat polar tip ups for many years and got tired of looking for them! I picked up a set of heritage lakers for this season and have used them three times! Worth every cent. One of my trips with these was in a 40 mph wind at 10 degrees with blowing snow. Can't lose these and the snow that builds up does not bother the mechanism at all. The flag arms are so long when it trips it actally draws your attention to the trap. I do miss seeing the top spin with a running fish but I spooled the lakers with white dacron with blue and red threads woven in. I can't see a running fish when I aproach the hole, but when I get to the trap I can look into the hole and see the spool spinning.
