The Max Stick XF16 and XF20 are carbon fiber retrievers that are fully repair/replaceable making it the last telescoping retriever you will have to buy. This is the 2nd GEN carbon fiber Retriever. The XF is made with a thick layer of carbon fiber (0.5 mm), as well as the traditional woven carbon fiber on the outer layer, greatly increasing the strength of the pole, making it THE most durable retriever on the market. The greatest feature of the XF is every part of this retriever is replaceable. If you manage to break any section of this retriever we offer replacement parts for a reasonable price, making this the last telescoping retriever you will ever have to buy.
