Tusa Talis IQ-1201 is very similar to one of previous model Tusa ZEN IQ-900, except some changes in data access and setup; also Talis has FO2 for both mixes for up to 100% and PO2 - 1.0-1.6 ATA (in Tusa ZEN IQ-900 these numbers are FO2 for 1st mix is up to 50% and PO2 - 1.2-1.6 ATA).

It is absolutely beautiful dive watch computer for recreational and novice divers who will find and appreciate its simplicity and pleasure of use. Nowadays many manufacturers of this dive gear incorporate features of standalone wrist watch with full functionality of scuba computers. And Tusa Talis is not an exception to this rule! You will wear it onshore with the same success and as a dive computer underwater!
As was mentioned above Tusa Talis IQ-1201 has 4 buttons: Mode, Select, Light, and Advance. Dive computer has two bar graphs to display nitrogen loading and ascent rate:
Display is devided into 3 areas: top, central, and bottom. All data is well structured and self-explanatory, so even novice divers will read it easily. Digits, symbols and text messages are sharp and well-visible at any angle.
Before diving I had to set desirable parameters, of course. As Tusa Talis IQ-1201 dive computer made with standalone digital watch functions, so the first parameters I set were digital watch parameters. It is really easy, I just followed easy to understand user manual - when and for how long press certain button and all the sequences! Digital watch parameters listed below:
All parameters of Tusa Talis IQ-1201 are divided into 3 Groups where you may set FO2, variety of alarms for Normal (Air/Nitrox) (for FREEdive you will set alarms separately and they are accessible from FREEdive Mode menu), and number of utilities. Here you will really need to practice with user manuals to get familiar with buttons combinations, because it may be confusing since the beginning! Below is a summary of what you may set for Normal (Air/Nitrox) mode:
Also at this stage I could plan my diving. Tusa Talis has standard function - Dive Planner with the range 9-57 meters. Dive Planner allows a diver to see for how long he/she may stay underwater safely and at what depth, according to current nitrogen or oxygen accumulation. Planning is calculated only according to FO2 set point for gas #1.
As a dive computer, Tusa Talis IQ-1201 operates in 3 modes:
Tusa Talis IQ-1201: Diving With Air & NitroxThat's a good practice to set Wet Activation to ON. It will activate dive mode when dive computer senses depth of 1.5 meters. When I set Talis for Nitrox, I had get following dive data on main and two alternative displays during No-Decompression mode.

Dive computer gives a choice to a diver to set ON/OFF to Safety and Deeps stops. Safety Stop factory preset for 3 min and depth 5 meters, and Deep Stop is factory preset as well for 1/2 max depth of the dive and for 2 mins. Tusa Talis IQ-1201 allows using 2 Nitrox gas mixes, we may swap mixes during a dive, of course, if we set 2nd gas mix. It is an easy procedure and works only from the Gas Switch Preview display. If you want to change to a gas mix with higher PO2 than allowed – dive computer will activate High PO2 alarm. It is still possible to switch to a tank with prohibitive gas mix only if in the tank in use is not enough gas to complete a dive. During ascent computer gives an Ascent alarm (audio, message ‘SLO’, and flashing ASC bar graph) if my ascent rates is higher than allowable at certain depth. This function is pretty sensitive, so diver needs ascending smoothly. As other scuba computers, Tusa Talis constantly monitors our O2 exposure and PO2 level. If you reach depth where PO2 level will increase to 0.2 ATA less than of the PO2 Set Point - dive computer will give you High PO2 alarm. Computer gives a High O2 warning when oxygen toxicity reaches to 80% (240 OTU) and alarm when O2 hits 100% (300 OTU) with all vital data displayed.
Tusa Talis IQ-1201 activates Decompression mode, if I exceeded No-Decompression Limits (NDLs). Upon entry into this mode you will hear a loud audio and applicable dive data will be displayed: UP arrow, Stop Bar icon and flashing NiBG with full 5 segments. From this moment all calculations will be made regarding to Decompression mode. Following information will be displayed at this moment on the MAIN DECO DISPLAY:
Decompression display has main and alternative screens. To move around displays – use A-button to see following information as a summary:
During decompression, diver may create, so called DECO Violations, which happen if he/she ascends shallower and stays for some time above the displayed decompression stop depth, or diver may descend deeper than Maximum Operational Depth (MOD), or decompression requires stop depth range between 18 m and 21 m deep. In this case scenario Tusa Talis activates appropriate Violation mode and manages it to help us safely perform decompression in those situations.
Tusa Talis IQ-1201: Diving In GAUGE ModeNext dive mode of Tusa Talis IQ–1201 is GAUGE. Dive computer doesn’t perform any calculations of nitrogen and oxygen loading and decompression. It can be used as a depth gauge and timer only. As with other dive computers, after diving with this one in GAUGE, diver needs to wait 24 hours before it may be used for diving with Air or Nitrox. Display shows dive data similar to listed below and it is a summary from main and alternative displays:
Tusa Talis IQ-1201: FREEdiveIn a FREEdive mode Tusa Talis works as a depth gauge and calculates nitrogen based on the default FO2 of Air and the amount that you may have after previous dives from the last 24 hours. For freediving dive computer has special set of alarms that you may access from Free Surf Main screen. Below you may find brief descriptions of them:
During freedive I had main and alternative displays like that:
After the Transition Period of 10 min I could access following modes:
Tusa Talis IQ-1201: What Divers Say
As you may see, Tusa Talis IQ-1201 may be recommended dive computer for the beginners, advanced recreational and free divers. It offers range of functions, which will easy satisfy demands of these categories of divers. Also should be mentioned improved and user-friendly interface with step back feature and it’s all in one small package of the size of wrist watch – and that is the main benefit for us! And it looks just "cool" on you wrist, as you may wear it as a watch – I got few nice compliments of people onshore about it!
I didn't find any difficulties learning this dive computer - user documentation was structured very well and thanx to that and user-friendly interface of Tusa Talis, I really liked setting this thing up and diving with it! During test dives I was very pleased with performance of this dive computer - very easy readable display, easy to change mix, perfect Safety & Deep Stops and DECO mode management. Price of this dive computer may be considered as a moderate and aligned with other similar scuba computers, like Sherwood Amphos, Oceanic GEO 2, and Tusa ZEN IQ-900.

Bought Tusa Talis for my Advanced Open Water certification and night diving. It is excellent dive computer; easy to read and see digits, even smallest, even at night. Computer gives all vital dive information - and nothing redundant.
I didn't have too big issues to learn it to set and understand during dives - everything is logical, just had to work out few button combinations.
Also I liked dual-gas function, freedive mode and Conservative factor function. Transfer dive data from Tusa Talis IQ-1201 to my PC was an easy process - all drivers and software worked well.
I recommend this dive computer to every novice diver and all recreational divers who don't need air integration.
