I run a Boundary Water Vexlar unit, but I dont think that is an available unit anymore...pretty sure that there are more cost effective and more modern units available...I am content with the unit; it aint broke so I dont fix it ;)There are many fishers here with sound wisdom and experience. I also am a suction cup guy, and vaseline helps it hold fast, and the gurgle is only a bother in absolute stealth mode...but I always am mindful when I head back to dry land with the transducer deployed...
