The Mastervolt Mass battery charger is designed to deliver faultless performance in the toughest conditions, providing a stable power supply to every type of battery used in boating, even those that are flat. The unit it made from lightweight stainless steel, in an anodised aluminium casing. The internal components have been coated to prevent damage from damp or condensation, ensuring long life and less chance of failure. The Mass battery charger is also insensitive to electromagnetic effects of other devices you may have on board. They have been tested at full capacity without stopping and have a MTBF (Mean Time Between Failures) of 180,000 hours.
They have one main outlet to optimally charge a battery bank and guarantee a long lifespan for your batteries even with daily and intensive use. There is a second outlet which is used for maintenance charge of your starter battery. The 3-STEP+ charging memory ensures more power and a longer life for your batteries. Mass chargers feature a Current Control function which prevents the fuses being blown when the voltage drops. It is also MasterBus compatible, meaning they can be connected easily to a MasterBus system where you can operate and monitor all Mastervolt devices in one panel. The Mastervolt Mass series of battery chargers are designed to be GMDSS (Global Maritime Distress and Safety System) compatible so you can comply with SOLAS (Safety Of Life At Sea) guidelines.

Happy with product - good value and prompt delivery
Great customer service and competitive prices.
Beaver Easy Fin Spring Straps Quick Release Medium
Great company, fast email communication, and very quick delivery.
I was looking for a new wetsuit and found these guys online. They had the wetsuit I was after and there was a link to an interactive sizing guide to help me identify the right size. After ordering I received an email checking I had used the chart to make sure I was aware and avoid getting the wrong one. Wetsuit arrived a few days later. Cannot ask for more.
Small order, but never the less a very positive experience. My replacement fins straps were not delivered (Christmas time order) when I chased this with Russell, his email reply was instant and positive. A new order was dispatched and received a few days later. Highly recommended
