Go with a Vexilar. Have a FL-12, which I have been using for years. Ended up buying a MarCum Lx6S Lithium as part of Ranger boat purchase. Have used it four times in the past two winters and already broke a cheap $14 plastic cover holding the USB charger on it. Contacted the Mfr and they said to buy a new one, as its past the warranty period. Cheaply made product, and poor customer service. I went to their website to buy one and they are out of stock! What a surprise. I guess that I am not the only one who purchased this defective product. Unless I get it for free again as part of a promotion, I will never again by a MarCum product!
