ProSport Generation 3 On-Board Marine Battery Chargers incorporate all-digital microprocessor control. Like no other, the new ProSport Series provides automatic installation feedback with its exclusive "System Check OK" and individual "Battery Bank Trouble" LED indicators, and also has the most advanced energy saving mode. After fully charging and conditioning batteries, ProSport's Energy Saver Mode will monitor and Auto Maintain batteries only when needed to maintain a full state of charge, resulting in maximum reserve power performance and lower AC power consumption and operating costs.

ProSport incorporates Distributed-On-Demand Charging technology, taking 100% of the available charging amps and distributing them to any one or combination of all batteries as needed for faster charging.

ProSport is 100% waterproof and shockproof, weighing 40% lighter than older technology epoxy filled chargers providing cooler operation and greater reliability. Each ProSport model has 4 digitally selectable charge profiles including a once-a-month storage reconditioning mode for extending battery life.

Features:

  • Microprocessor and software controlled pulse charging technology delivering a 40% lighter design than the previous generation of epoxy filled chargers, cooler charger operation and faster charging.
  • Advanced technology eliminates time consuming troubleshooting by clearly indicating system and battery connections are OK or if a fault is present on a specific battery bank.
  • Fully charge and extend the life of your batteries. Automatically charges, conditions and safely maintains all batteries on board for maximum time on the water.
  • After fully charging and conditioning batteries, ProSport's Energy Saver Mode will monitor and Auto Maintain batteries only when needed, maintaining a full state of charge. This significantly reduces AC power consumption, lowers operating costs and maximizes reserve power performance.
  • During short or long-term storage, ProSport automatically reconditions all batteries on board once a month for maximum battery life and performance.
  • Automatically charges and maintains your engine crank battery while distributing all remaining charging amps to trolling motor or house battery(s).
  • LED indicators for Charging, Conditioning and Auto Maintain modes in addition to AC power and selected battery type (2 charge profiles to choose from with a 3rd high performance AGM HP profile on the ProSport20 Dual only).

Comfort and style!
Size: 9.5, Color: Brown
Very light weight and also fashionable, they fit well right out of the box. I wear size 9.5 and have a slim foot and put them on and wore them hem for about an hour to “break” them in, and they felt very comfortable and have remained so without any blistering or discomfort. I appreciate the small ‘nubs’ built into the sole and the extra padding in the heel. Even our 6 year old grandson was impressed: the white sole has “air holes” for extra cushioning and he said, “They look like Nike AirMax 270’s!” Not bad for a quarter of the price. Well made, and I am hoping that they will endure frequent use.

My “go to” work shoes
Size: 9, Color: Brown
I think these look great, sporty and office appropriate for men as well outside of a really formal setting (wouldn’t pair with my suit but for chinos and a polo, it’s perfect!). The main thing I want to talk about though, is COMFORT. Man these are great! I’ve always had flat feet with discomfort after a few minutes of standing. With these on, I find myself using my standing desk for over an hour when I first get in and taking walks around the building during break time with ease. No tired feet when I get home and I think they look pretty cool to top it off. Great value.

Pleasantly surprised!
Size: 10, Color: Black
They look kinda of cheap and like old man shoes in the box. I was not expecting much as they were very inexpensive. They were boxed really cool with each shoe having its own sleeve and are true to size (Size 10). Comfortable and sturdier than they appear. They are very cushiony and look more stylish when you're wearing them. I thought they would wrinkle immediately upon wearing them but not so far. Was caught in a rainstorm and when they dried they were still like new. For the price (Just over $30 because I did not clip the coupon, grrrrrr!) they are well worth it. I am pleasantly surprised.
