I have a Dual Pro Sportsman Series SS3, Three 10-Amp Banks, 30 AMP 3 bank 12V – 36V charger that I took out of my 721 to upgrade to a 4 bank charger.
It's in excellent condition. Charges and maintains batteries like it should. It's very clean with no scratches or dents, etc.
MY 721 was put in service Nov. of 2013, so the charger has had about two years of use (the Pro XS had 67 hours on it when I bought her). I don't know if that was 24/7/365 of use because I've only owned the boat since the beginning of Dec. 2015.
I'm asking $225
(or make a reasonable offer)
In order to save shipping charges, local pick would be ideal but I will ship it at the buyers expense. SS3 4.75H x 8.00W x 11.25L 15.50 lbs.
(To give you and idea, UPS ground shipping from Schertz, TX to the Austin area from here, is about $25.)
