The only way of finding the limits of the possible is by going beyond them into the impossible - Arthur C. Clarke
Vexilar is a well known company for making fish/depth finders for both your boat and your ice fishing gear. You can buy the Vexilar FL-18 Ice pack for ice fishing and when spring rolls around, the right accessories will turn it into one you can put on the dash of your boat. Different accessories turn it into a portable one so you can take it out of your boat every night and easily put it back the next morning.
You wonder why you see so many people selling their Vexilar equipment when you read the great reviews it is getting. A lot of fishermen would rather have two different depth finders so they can have one set up permanently in their boat and the other with their ice fishing equipment than change them back and forth. Another reason is that they keep coming out with newer and better 
equipment, so the fisherman wants the newest technology. If you read the whole used Vexilar for sale ad, a lot of times they will tell you they have two others, or they do not ice fish any more.
There are a lot of places you can find used, refurbished or reconditioned Vexilars. Just type “used Vexilars for sale” and there are ads. Vexilar sells reconditioned products and gives a brand new warranty on it. EBay has used ones for sale and there are a lot of private ads online. Calibex sells some refurbished ones.
You will need to carefully check it out before buying a used one from an individual, making sure all the parts are there and it works. The good news is you can get some really good deals if you check around. Look online for used Vexilars as sometimes companies take them in for trade, so if you do not find what you want today, try back again tomorrow.
