I bought my 40V before the 24V was around. After 5-6 seasons with the original batteries, I probably get 40-50 holes per battery when you’re cutting through 20-24″ regularly. So 80-100 holes is plenty for me when I’m trying to chase schools of crappies around. If I need a new auger today I would probably go with the 24V just for the weight difference, probably just buy 2-3 extra batteries. Never held or used a 24V, so not sure if the lower unit is less durable.
For those who have the 40V strikemaster, Why the 40V over the 24V. Looks like retail price is 169.00 less on the 24V in 8″ 599.00 VS 430.00 ) Weight is 10 Lbs less in 8″ ( 24 Vs 14 ) I would think the 169.00 savings would buy you a extra battery. The 40V says 100 holes per charge. The 24 says 50. So 2 batteries would + 100 homes, The same as the 40V. This is with the standard auger – Not the lite flight. I just think the lighter 24V with a extra batter would be the better choice
