These are new to us this year, the Gemini Series from Hotline are a new concept in electric fence energiser. They some as a complete unit with two input leads that give you the choice of running them from either the mains or from a 12v battery. They have a very sturdy jack plug socket in the side and can sit outdoors and be wired into a 12v leisure battery or a can be brought indoors and plugged into the maiins. The units come with both adapter cables as standard. we'll be puting them with some of our kits shortly but if you'd like a kit put together with these fencers, please get in touch and we'll put one together for you.
