Posted this for those without a flasher but have a fishfinder with flasher.
I have used my Vexilar for the last 15+ yrs, this yr I bought a Garmin Plus 4cv and it has a flasher so gona try it on the ice.
Didn't want to carry it all loose so I found a bag at Walmart for $6. The bag has a compartment on top and the front if needed.
Here's some photos of how the unit +battery is packed in the bag it all fits. The ducer is hanging level so it should work. I'll used part of a pool noodle for a float and clothspin to adjust the ducer depth.
Edited: photos that show the setup I'll use. With the units base attached to the wood base I can't fit the finder inside so it sets on top the wood.
