i just ordered KeyBak super 48 retractable keychain to use with my next edc-flashlight.
its for occasions i cannot be sure that clip will hold the light on my pocket. i will attach a lanyard to light and clip that lanyard onto keybak, that way i can put the light bottom of my pocket and pull it out by lanyard and point it everywhere my arm reaches (guess 48" of cord +4" lanyard is enough reach
and then let it just swing back to my waist if i drop it or something.
also i think if this is not viable solution id look for those keychains made of cork or plastic that float.
or those things designed to cellphones.. see thru and operational even when inside and they keep water out and float..
i used to make my own while going boating..depending what i had with me.
paracord and piece of wood or cork.
or duct tape and twobyfour..
also for keys i used big pain killer plastic containers with solid lids.. keys inside and lid closed.. and duct tape to ensure seal. white can is easy to see bobbing in waves.
i always found my carkeys etc even if they fell off the boat. hahah
yeah duct tape is macgyver must!
but retractable keychain is a new idea to me.. will start testing next week
with lummi raw or fenix tk11
