I love the Nox 800... took it out on my first beach trip it handles saltwater and sand no problem dug deep targets all day long, the little purse pendant thing I hit at 6 inches in ankle deep water at the shoreline. rang nice and clean. Machine was stable all the way to 25 near the water, near the parking lots i could use it at 22 stable...Sadly I took my Excalibur II all the way to Cali also and it never left my trunk :(
I did however notice there is an issue with at least my connection in the upper shaft area, it is developing a wiggle. hopefully something minelab can address, and yes the cam lock was tight. Not a huge issue but hoping it doesnt get worse. Another note the wireless headphone earcuffs are narrrow by design and they did tend to hurt after a bit, overall comfortable though and they kept my ears warm. Beyond that I have Zero complaints. It performed flawlessly.
