Sorry for the confusion gentlemen, I do have a Otter cabin now. I did as Dave said and I could see bottom fairly well with bright sun. 2 of the windows peak a little light but I think I can fix that. I just don't want to buy a spear and saw and then find out I can't see anything. I speared many years ago but from a permanent which some locals decided to drive through with there truck it cost me $800 bucks back then it was really nice. Now that the hurt has gone away I thought portable would be the way to go. Thanks for the help.
