Summary: Humminbird PiranhaMax 220
Comment: I have to give it a five because it is exactly as advertised. It functions as advertised. I use it in 5' to 30' and it when set up (using the menu) as suggested it shows the stumps, brush, and stickups. I think that some would say it doesn't do this or it doesn't do that but COME ON, it only cost 100 bucks. My bottom line on a product is it a good value for the money. Yes this is.
Customer Rating: Summary: Reliability in question
Comment: Received this device last year; it was easy to install and operate (except that the printing on the on/off button was upside-down). It did everything I expected of it for a while.
Unfortunately, one year and 14-days after purchase (just after the warranty elapsed, of course), it stopped working. Nothing happens when I push the on/off button. Got power to the plug... just doesn't come on.
One very unhappy customer.
Customer Rating: Summary: Fish finder / depth guage
Comment: Easy to install and operate, used mostly for a depth gauge in shallow water great unit for the $'s if you don't need color or a GPS, couldn't ask for more; it does what it is supposed to do, finds the fish and lets me know how deep the water is. Very portable if you dock the boat just unplug it and take it with you. Did a lot of research before choosing one, online and at the local stores. Own a few other Garmin units (GPS's) they are the best IMO.

Summary: VERY PLEASED
Comment: I have only had a couple of trips out with this unit but what experience I have with it is all good. Accurate and easy to read.
Customer Rating: Summary: Great Finder that works for any boat!!
Comment: I purchased this Fish Finder to use it on my X-Factor Kayak. I wired it up with a 12vdc 8ah battery and it runs for days on end with out a recharge. This finder is great if you just want the basics, but I think for about $50 more you could get a little nicer unit like the Matrix series. If your looking for something small and cheap this is the way to go. If you want GPS and other features look else where.
