I function a portrait studio in Honolulu, Hawaii, and for the beyond years i have been using the Sky Ports transmitter and receivers to hearth my flash units. i take advantage of them both inside the studio and on place.formerly I used the Pocket Wizards and became very glad with them until my gear bag became stolen along with my Pocket Wizards. That changed into whilst i bought the Sky Ports.Sky Ports are about half of the size and weight of the Pocket Wizards at 2 3/eight x 1 five/8 x ½”, and approximately a third less steeply-priced to buy. through assessment, the Sky Ports price is very appealing. And considering they each paintings on the equal major of radio transmission to fireplace flash units, I figured i might provide them a try.they’re very small, which I suppose is an asset specially on region. they arrive with their personal custom wearing cases. each case is a compact and nicely padded, semi hard-side case that holds both one transmitter and one receiver, or receivers.The transmitter attaches to the digicam via sliding onto the recent shoe, and the receivers attach to the flash gadgets by a short cord and plug.I commonly use or three flashes so i bought the one set of 1 transmitter and one receiver, and a further receivers. The transmitter makes use of a small nicad battery much like some watch batteries. This battery powers the transmitter for approximately and a half of months of everyday use. The receivers have a battery constructed in to them, which wishes to be charged approximately every 3 months.they have got four distinct channels on which you can perform them just in case there is something within the vicinity inflicting interference, or if you have some other photographer the usage of Sky Ports in the area.i have never tested the maximum distance for which they may be used, however in my revel in, they paintings very well and consistently. I generally best use a distance of underneath 20 feet among my transmitter and the receivers, but i’ve used them indoors and around corners with no troubles in any respect.The most effective criticism i have about the Sky Ports is that they have no battery indicator telling you that the battery is getting low and wishes to be recharged or changed inside the case of the transmitter.aside from the lack of battery degree indicator, i’ve determined the Sky Ports to be an awesome investment and approach to cord-loose flash firing. The deliver instances provide good enough safety, and their size and weight are an advantage in packing and wearing.
