Question about FishHawk 840 probe.

[Meals-On-Reels]

I know with my old 800 series FishHawk I had to swap out the battery connector (flimsy type 9v connector) to a higher quality rigid 9v connector. I think it had something to do with increasing battery life. It really seemed to make a difference.

Is there a need for this with an older 840 too? It still look like a cheaper type connector. The one on my Depth Raider looks better than it too.

Thanks.
