Max. pressure
The maximum operating pressure of the sprayer.
High pressure allows to achieve good spraying performance and range, however, actual performance can vary with units with the same pressure. Therefore, in general, the indicator is for reference (the lion's share of models has a
pressure of 3 bar and
4 bar, and it is only possible to compare different models by it approximately. When choosing, it makes sense to focus on more practical characteristics — performance, range, etc.
Hose length
The length of the hose supplied with the sprayer.
The longer the hose, the farther the spray tube can be reached without moving the sprayer itself. However, this is true mainly for wheeled and universal sprayers (see "Carrying type"). In shoulder-mounted units, the hose is usually selected in such a way that it is enough to comfortably hold the tube in your hand, and this parameter in such models most often does not exceed 150 cm.
It is also worth considering that long hoses can be quite bulky; however, this disadvantage is often eliminated by the use of spiral hoses, which are stretched to their full length only when necessary.
Telescopic wand
Availability of a folding
telescopic tube in a set of delivery of a sprayer.
The length of such a tube can be adjusted within certain limits, adjusting it to the specifics of the situation. For example, in cramped conditions, a large length is not needed, but when processing tall trees, on the contrary, it is very convenient. Specific adjustment options may be different: in some models, you can choose only one of the two extreme positions (fully folded or fully unfolded), while others allow you to fix the handset in intermediate positions.
Spray lock
A device that allows you to fix the trigger (switch) of the sprayer in the pressed position. This is especially convenient for large volumes of work: holding the trigger manually for a long time is rather tiring, and
the continuous watering lock allows you to avoid unnecessary stress on your hands.
Note that this feature can be found in all types of sprayers (see above), including lever ones — many models with this type of action are equipped with both a pumping lever and a separate trigger that must be kept pressed during operation.
Wand holder
The presence
of a tube clamp in the design of the sprayer.
Such a latch is a set of special clips, usually installed directly on the tank. It greatly simplifies the storage and transportation of the device: the handset, usually, is placed as compactly as possible and at the same time securely. Yes, and during breaks in work, this feature can come in handy — fixing the tube in the retainer is more convenient and safer than putting it on the ground, holding it in your hands, etc.
