I am in the market for a float tube that is safe for my eight year old girl. I need one that will sit her high enough to cast or that has low back rest and arm rest. Can someone give me a recommendation? I am trying to keep it cheep because if she doesn't like using it or if she gets good really quick we will need to upgrade or get rid of her starter tube. I do know that they did at one time make a youth float tube (can't remember what company) but I haven't seen one in over a year and the only ones i have seen were on ebay. I use a Utube but what would you recommend for young kids?
