Electric reels were not popular for inshore fishing in th US until recently
But it can change soon. The traditional electric reel is very heavy and reguires a heavy battery and code. But new Japanese electric reels are as light as 25 - 27 oz and don't require heavy battery and battery code as it has built-in small battery. So you can jig with the electric reels for long hours, you can cast or you can even mug by moving around the boat freely.
I am not in favor of electric reels and I ask not to bring any electric reels on my charter. My ultimate goal is to land a swordfish on jigs daytime by jigging in 2000 ft deep manually.
However I feel the new trend is coming even for inshore jigging.
