Power wattage

This refers to the amount of power that the finder expends to give forth the associated end results. So that you do not spend too much on power, go for one whose ratings are low.

Number of pixels

With or without Transducer

You have the dual options of working with or without the transducer. However, for the sake of enhanced performances, we suggest that the item you work with contains a transducer.

A. YES, it is! It lets you scan a huge area that ultimately leads to greater catches for any amount of time you invest in the trade.

Q2. Where do you mount a transducer on a boat?

A. Ideally, this should be as close to the central part of the boat as can be. This is to ensure the stability you need to ply the turbulent waters without capsizing.

A. At the exact tip of the bottom of the boat as can be. That is to let it have the maximum impacts and access to the surrounding waters.

Q4. What’s the difference between deeper Pro Plus and chirp?

A. These two differ with regards to the kinds of transducers employed, the frequency of use, and the kinds of ultra-sound sound pulses engaged for the job.

Q5. Is side imaging better than down imaging?

A. In shallower waters, yes. However, you may have to opt for the down imaging in the deeper waters. For the sake of your maximum convenience, you need both at the same time.
