Thanks for all the input guys. In my initial inquiry, I intentionally did not expand beyond the electric as an option.
I do have a nice gas saw which I can use. I also have a nice 20 volt Dewalt drill which I use with my auger. I can buy a 20 volt bare tool saw for around $60-$70 and would be willing to go that route to go cordless.
It sounds like a 20 volt system is insufficient to do the job well.
Seeing as I already have a gas saw which I know will do the job, I’ll go that route. I was just hoping to stay cordless with my ice fishing/spearing equipment without a big investment in tools not compatible with my present gear.
The cordless (armstrong) saw I have now, needs a rest stop or two to get the job done. This has a tendency to influence my choice to move to a new location when the spearing is non productive at my current location.
Again, thanks for the input. Tight lines and stay safe.
