If you have up to a 5" Garmin Stiker 4xx or 5xx (any model), Echo series (any model), Echomap 4x, 5x (any model) this mount will support your fish finder and transducer mounting and powering it on your favorite float tube or inflatable pontoon/watercraft all day long - so again, literally everything you need to mount and power your Garmin fish finder all fishing day long!  And in fact, if you put something like the Garmin Striker 4 on this kit, you will have enough juice to run that finder for a couple of good days of fishing.
 
If you need a battery charger for the 5ah SLA rechargeable battery that can be selected with this mount, we sell a good one separately on our website here: https://www.fishfindermounts.com/product-page/800ma-charger
